Best of Swarfcast – Ep. 73 – Tracking Your Machine’s Productivity with Eric Fogg

By Noah Graff

Today, we’re going to do a quick Throwback Thursday to March of this year, to a discussion about going digital with machine data.

This week’s podcast is an interview we did with Eric Fogg, co-founder and head of machine connectivity at MachineMetrics. MachineMetrics produces an IOT device that connects directly with machine tool PLCs and controls to track realtime and historical data on equipment. Operators use the data to assess how machines are truly performing, which is often quite different from what they perceive.

Main Points

Eric explains that MachineMetrics is a machine data connectivity data platform. The company makes a device (he calls an “edge device”) that connects directly to machine controls and sensors of production equipment. The device gathers valuable data on how the machines are performing and sends it to operators to analyze. (3:10)

Eric talks about taking machine shop classes in high school. During high school he worked at a lot of different machine shops on nights and weekends and taught himself programming. (4:10)

Eric says that MachineMetrics can gather data from all vintages of machine tools, not just CNC machines, though CNC machines provide the most data. He says right now MachineMetrics has a client using its edge device to gather data from a punch press that was manufactured in 1925. He says, “As long as it moves and has electrons flowing through it we can probably get some useful data out of it.”(7:00)

Eric says that in college he majored in theology because he wanted to work in the field of corporate ethics. Eventually he started his own machine shop in his mid 20s that specialized in green technology products. (10:00)

Eric Fogg of MachineMetrics

Eric says that when the 2008 recession hit he started doing more job shop type work with low margins. He eventually closed his company started doing Six Sigma consulting for job shops in Vermont. The experience of analyzing the processes of different shops inspired the idea for MachineMetrics. He says he observed that shops were often making decisions based on a gut feeling rather than based on data. He came up with the idea to pull the data that already was on the machines’ controls to create reports, dashboards and analytics to help machining companies make decisions. (14:00)

Eric says the most basic data MachineMetrics tracks is machine utilization—how much machines are running versus how much people think they are running. He says the average perceived utilization of equipment by MachineMetrics’ customers is just under 80%. The actual average is in the high 20 percents to low 30 percents (the numbers are based on active shifts). He says that the numbers can be surprising as various markets differ. For instance, he says for some types of very low volume work (1 or 2 part runs) 15% utilization might be considered world class. He says for high volume shops utilization is often much higher. For instance, he says shops making millions of parts with much thinner margins sometimes have utilization in the 90 percents. He says that no matter what type of shop, clients are usually surprised at their utilization rates. (20:25)

Eric gives some examples of how MachineMetrics data uncovered problems that led to low machine utilization. He gives an example of a client who was using cheap 1/4” drill bits on a drill and tapping center. The company calculated it took only 5 minutes to change a drill bit out, so they used cheaper ones with short tool life. The problem was that while operators left to get a new drill bit from the tool crib they got sidetracked and the average time to change the drill bit was actually over 40 minutes. After learning this the owner of the company decided to go out and buy the most expensive drill bit that lasted 10 times longer than those he was using. It was a solution that was much faster and easier to implement then changing the procedure in the shop which could have tons of variables to consider. (24:10)

Eric says that MachineMetrics generally does not advise customers how to use the data they collect. He has found that customers usually take the initiative to solve their problems. He says his company is often surprised at the interesting ways that clients utilize the data. (27:40)

Eric discusses a phenomenon he sees in CNC shops he calls “cyclecreep.” What happens is that over time people gradually alter they way they run jobs by making tweaks such as changing tools or feed rates which often increases cycle time. The problem is that the manufacturer continues to bill its customer for the original cycle time. Operators see green lights on machines which makes them think everything is running fine but problems are occurring behind the scenes. (30:15)

Eric gives an example of a company running the same parts on 20 vertical machining centers that were bought over 10 years. MachineMetrics found that no two machines had the same original cycle time of 40 minutes. He says that some cycle times only differed a few seconds but the delta between fastest machine and the slowest machine was 15 minutes. After seeing this data, in just a week the company was able to adjust the machines to all have a cycle time within a few seconds of each other. (35:30)

Eric says it can be difficult for his clients because often MachineMetrics is delivering them bad news. He says that the consistent trend he sees is that the most successful shops have a culture around change. (37:25)

Ep. 96 – Precision Machining in Spain with Patrick Bosch

By Noah Graff

On today’s episode we are discussing the machining industry in Spain.

Our guest is Patrick Bosch, Managing Director of Nagamohr, a 150 employee Tier 2 automotive company headquartered in Madrid, Spain. According to Patrick, despite Spain’s reputation as having a relaxed culture, its people are quite serious about manufacturing.

Scroll down to listen to the podcast. Or listen on your phone with Google Podcasts, Apple Podcasts or your favorite app.


Main Points

Patrick talks about his family’s German origin and about a subsidiary his company started recently, Nagamex, in Mexico. (2:55)

Patrick talks about Nagamohr’s business, producing turned parts for Tier 2 automotive. The company has over 80 machines in its shop in Spain, including a large number of Hydromats, as well as CNC multi-spindles and other CNC machines. It has a turnover of around 15,000,000 euros per year. (4:05)

Patrick says Nagamohr was originally a joint venture between a Spanish firm and a German firm, Nagares and Mohr, but the two could not get along, even while the company just existed on paper. Nagares, the Spanish division, wanted out of the partnership, so Patrick’s family took its place. Only a few years after the company was founded, the Bosch family assumed full ownership of Nagamohr. (5:25)

Patrick talks about his background. He studied business administration and engineering at university. For a few years he worked in the finance field, but when the opportunity arose he decided to join his family’s company in 2011. He assumed a leadership role in 2013. (6:40)

Patrick’s talks about why his family moved to Spain. He is the first generation of his family born in the country. In 1962 Patrick’s father originally visited Spain to study Spanish, but decided he preferred to stay in Spain than return to Germany. Patrick’s mother is also German. (8:00)

Patrick says that the automotive industry represents over 10% of Spain’s GDP. He says Spain’s manufacturing is most significant in the country’s Basque region (in the north) as well as Catalonia, while his location in Madrid ranks third. 

Patrick discusses the division between the regions of the Spain. He says half of the people in country identify themselves as Spanish, while the other half of people identify themselves by their region. (11:45)

Patrick talks about the skills gap in Spain. He says it’s hard to find skilled workers in the machining field, so usually its necessary to train employees in house. (13:10)

Patrick talks about the industries commonly found in Spain besides automotive, including the energy industry and engineering. (14:40)

Patrick says unemployment in Spain fluctuates quickly and can be very high because of the country’s reliance on the seasonal tourism industry. He says before the COVID-19 crisis the country’s unemployment rate was around 11%, but right now it is around 18%. (15:22)

Patrick dispels the myth that Spanish people are lazy workers. He says the Spanish work day is similar to that of other countries but the custom of the Spain is to operate one hour later than the rest of the world, as though it were in another time zone. For instance, someone working in a shop in Spain might start at 7:00AM rather than 6:00AM, but then work an hour later in the day. Rather than eating lunch at noon,  Spanish people often eat lunch around 2:00PM. Then they typically start eating dinner around 8:30PM and as late as 10:00PM. (17:10)

Patrick discusses salaries in Spain and Spain’s government-run programs such as health care. He says salaries range widely, with entry level in a shop around 20,000 euros a year, with an additional 33% going to the government for social security and health care. He says that Spain’s public health care is very good. He says inexpensive private insurance is also available but generally everyone uses the public health care providers for serious medical concerns even if they have the private insurance. He jokes that he always asks himself why he pays for private insurance. (18:50).

Patrick says people in Spain work much harder than other nations realize.  (21:20)

Patrick explains the origins of Nagamex, Nagamohr’s Mexican subsidiary, which was originally conceived in 2015 (See video below). Two major customers suggested the company should build an additional facility to be a local supplier to North America. It started the company there two years ago. Patrick says the biggest challenge of working in Mexico is the paperwork. He says there is significant employee turnover there but also many good workers. He also says he hasn’t encountered any corruption there so far. He says the Spanish language and Western culture was one of the driving factors behind building a plant in Mexico rather than in Asia. (21:55)

Patrick says business slowed for just a few months due to coronavirus. He says demand for automotive parts is at its peak during September and October, after which it will be easier to see where the company will be in the future. (25:50)

Patrick says that 99% Nagamohr’s work is automotive. The company was hit hard by COVID-19, with a reduction of more than 70% for two months. Business has picked up somewhat in the last few month. (27:00)

Patrick talks about something new he learned recently. He says two weeks ago at the beach he saw someone riding a special bicycle on water. (27:45)

Best of Swarfcast – Ep. 35 – Graeme Sinclair on Precision Machining in Australia

By Lloyd and Noah Graff

Our podcast team is taking a short break to enjoy Labor Day weekend with our families. In the meantime, in keeping with the international theme of Season 4, we hope you will listen again to the podcast we did with Graeme Sinclair, owner of Parish Engineering, a machine shop in Melbourne, Australia.

Scroll down to listen to the podcast.

On today’s podcast we interviewed Graeme Sinclair, owner of Parish Engineering, a prominent precision machining shop in Australia. Graeme has been in the machining business for 60 years, since he served his apprenticeship at age 14.

In the interview, Graeme discussed the challenges faced by machine shops in Australia verses the rest of the world, his eclectic taste in CNC machines, and his passion for the game of squash. Sinclair explains that one reason he has many different types of equipment is that automotive companies have shut down their operations in Australia, meaning a lot of high volume work has disappeared.

Main Points

Graeme talks about being a long-time fan of Today’s Machining World. He used to receive the printed copy of the magazine before it went digital and enjoyed sharing the printed articles around the shop. He talks about Lloyd offering him screw machines in the past. (2:40)

Graeme speaks about Parish Engineering, which was created by Mr. Parish in 1932. Parish ran turret lathes and single spindle cam screw machines such as INDEX B60s. In 1968, with no one to take over the company, Parish sold the company but remained to train others. Graeme joined the company in 1972 but was laid off in 1975. In 1980, Graeme returned and bought the company with his brother-in-law. His business partner retired in 2010, leaving Graeme and his daughter as the current owners. (4:30)

Graeme describes the company as a screw machine job shop with 28 CNC lathes and several vertical machining centers. The company owns Citizen, Star, Mori Seiki, Tsugami, Nakamura Tome, and INDEX machines. Graeme says he prefers Citizens for Swiss work. (6:00)

Graeme says the company made parts primarily for the automotive industry when he assumed leadership in the 1980s. It still does some automotive parts, specifically for the Ford Ranger, because the gear shift is made in Australia. Forty percent of the company’s current business is making pneumatic couplings and air fittings for track braking systems. The remainder of the company’s business comes from contract jobs. He says he is pretty sure the Ford Ranger is assembled in South America, South Africa and Thailand. (7:00)

Graeme talks about growing up in Melbourne, Australia, and how he got into the machining business. At 14, he left school because his parents were very poor and began an apprenticeship in fitting and turning. For 10 years, he went to night school three nights a week to get a degree in engineering. Both of his daughters are also mechanical engineers; one is the CEO of Parish Engineering and the other works in New York. Graeme is 74 and has been in the business for 60 years. He says he is finally down to working just five and a half days a week. He says he starts work at 8AM or earlier. (9:00)

Graeme says he didn’t plan to get into the machining business, but got into fitting and turning because it seemed like a good opportunity for someone with little formal schooling. He also worked in the machining business in England for a short time. (10:40)

Graeme talks about the differences between screw machine shops in the US and Australia. He has visited shops in the US and England, and says it seems like they all are facing the same challenges. The main difference he says is the US not using the Metric system. (12:20)

Graeme says about 20% of the parts produced by Parish Engineering is exported. (13:10)

Graeme says he still has use for multi-spindle screw machines. Three years ago, he acquired a second machining business, which he has been growing. He is thinking about adding another multi-spindle to handle high volumes. CNC work is diminishing slightly because of Australia’s declining auto industry. He says Australia doesn’t support manufacturing as well as other countries. He says manufacturing is strong but not as strong as it used to be.(13:40)

Graeme talks about the skills gap and how there are fewer jobs in the machining industry, as well as fewer skilled workers to fill them. He says many of his employees are immigrants because Australians are not as interested in working in manufacturing. He says Australians believe strongly in getting a college education, but many graduates struggle to find jobs in their fields of study. (14:10)

Graeme explains that immigration to Australia is not difficult for skilled workers from more developed countries. He says Australia is very culturally diverse and that the number of nationalities in Melbourne is close to 200. (17:20)

Graeme describes the differences between Sydney and Melbourne. He says Sydney is larger and closer to the mining industry, but Melbourne is the metal working manufacturing hub of the nation. Graeme says Sydney is similar to New York while Melbourne is Australia’s fashion capital and sports mecca. (18:40)

Graeme talks about playing squash, a sport that he has enjoyed for 57 years. He is the captain of his team and says he can still beat players 26 years younger than he is. He says the difference between racquetball and squash is the size of the ball and rackets. Both sports are played on the same court, but he says squash is faster and more challenging. He says when he was growing up, everyone played tennis. (21:20)

Graeme discusses the relationship between Australia and China. He says China is one of Australia’s closest large countries and its biggest trading partner. It buys a lot of Australia’s wine and agricultural products. Graeme says doesn’t buy much tooling from China and sells only one part to a Chinese company on an infrequent basis. (25:00)

Graeme says many Southern Australians where he lives are not fans of President Trump. He says many people including him regard Trump as “unprofessional.” Graeme says his business has not felt much impact from American foreign policy. (26:20)

Graeme says his businesses are going well and they consistently make profit. He says Parish Engineering is the oldest machine shop of its kind in the Australia. He says it has about six competitors of the same caliber. He says his philosophy is not to relax when things are good, and not to worry when they are bad. (28:35)

Graeme describes himself as hands-on. He spends a lot of time problem solving and trouble shooting on the shop floor. While he doesn’t mind time in the office, he says being on the floor is the best way to utilize his 59 years of practical shop experience. (30:20)

Graeme says having his daughter as CEO gives the company more purpose, knowing that the business will continue into the future. (31:25)

Graeme discusses the additional Lico CNC machine that he is looking to purchase for his company. He likes that it is quick and flexible. (31:50)

Ep. 95 – The Machining Business in Canada with Sander Boelen

By Noah Graff

This week we head to Canada, as we continue our season exploring the diverse world of machining around the globe. Our guest is Sander Boelen, founder of Allegiant 3D in Montreal, Canada. Allegiant 3D engineers and produces prototypes for OEMs in the photonics industry around the world; companies making products like lasers, medical instruments and dental scanners. 

As a used machinery dealer I’ve sold a lot of machines into Canada over the last few years. From my vantage point, the machining business generally seems to be doing quite well north of the border, and I wanted to find out why that is.

Main Points

Noah talks about meeting Sander Boelen when Sander inquired on Graff-Pinkert’s Trumpf TruLaser Station 5005 Laser Welder it has for sale. (2:40)

Sander talks about the origins of his company, Allegiant 3D, which began in the mid-2000s as an engineering firm. The company designs products and manufactures prototypes for the photonics industry, including lasers, receivers, and various types of medical equipment. (4:00)

Sander gives an example of the types of businesses he works with, including a local producer of intraoral scanners used in dental work. ( SEE VIDEO BELOW – 6:30)


Sander talks about the machine tools that Allegiant 3D has in house to make prototypes for customers. (8:00)

Sander talks about his personal experience growing up in the southern region of the Netherlands, which he calls a great breeding ground for technology. In his college years, Sander moved to Canada to take an apprenticeship in the Physics department at McGill University, located in Montreal, Quebec. (9:00)

Sander talks about higher education in Canada. He says public education there is free and universities are inexpensive, with tuition costing around $2,500 CAD per year. He says many Americans study in Canada because of the low cost. He also says Canada has good trade schools, including one close to his shop. (11:30) 

Sander talks about Montreal, located approximately five hours from Toronto. He says in Quebec French is spoken in the street and signs are in French, but everyone knows English. (13:00)

Sander says that Montreal’s machining industry is mainly in the aerospace sector, while machine shops in Toronto, which aren’t far from Detroit, primarily work in the automotive industry. He talks about some of the aerospace suppliers in his area which range greatly in size.

Sander says Canada is a good place to start a machining company but at the same time it’s complicated to start a business anywhere in the world. (16:30)

Sander talks about the Canadian government. He says Canada has good programs that encourage business. He talks about R&D tax credits that encourage companies to be innovative and work together. (17:50)

Sander says he believes that running a machining company in Canada is not that different from running one in the United States. In fact, currently he is looking for potential opportunities to start a company in the US. He also says that Canada’s economy is very socialist, particularly Quebec. He says not needing to provide health care for employees was one reason it was easier for him to start a company in Canada, which has a public health care system. He says that successful companies in Canada often offer supplemental insurance as an extra benefit to employees. (19:00)

Sander talks about the higher tax rates in Canada. He says at a certain income bracket tax rates can be 50-55% but there are ways to decrease taxes such as investing in pensions plans. (21:40)

Sander says that the machining industry in Canada will be prosperous for the next few years and that he sees work coming back to North America. He says that though the value of the Canadian dollar is much lower than the American dollar the lower value is beneficial for exporting. He says currently the aerospace industry is taking a hit, but his business is busy right now. (23:00)

Sander talks about the advantages of having a niche, making parts for the photonics industry. (24:50)

Sander says a big challenge he is facing is having to say no to the demands of smaller customers as his company continues to grow. He also says it is a challenge to produce the right parts consistently all of the time. He says making one part well is easy, but making a lot of different parts consistently is difficult. (25:30)

Sander says the most interesting thing he learned recently is that pushing employees to work longer hours often has diminishing returns. (27:00)

Question: Is doing business with Canadian companies important for your business?
