On TRAK to Industry 4.0

TRak Machine Tools brings digitalization to job shops

Job shop owners know digitalization is coming. Now, they have a familiar and trusted machine tool partner to help them meet the challenge.

“There’s the closing scene in the first ‘Terminator’ movie,” says TRAK Machine Tools owner Steve Pinto. “Sarah Connor is escaping because she knows that Skynet is coming. She’s in Mexico, and a young boy points to the horizon speaking in Spanish that a storm is coming. And she looks off and she says, ‘I know.’”

Job shops are facing the digital adoption challenge across two fronts—toolroom and production. “The transition across the business will be difficult for job shops,” Pinto says. “Especially owners that do not have teams of engineers and IT specialists to help them evaluate and integrate new, digitally enabled machining operations.”

As a first step to help shops on the toolroom side, TRAK developed a line of machining centers, powered by the company’s popular ProtoTRAK® CNC. Now the company is introducing an all-new line of production-level machines empowered by the Siemens SINUMERIK ONE “digital twin” CNC platform.

The Transition to Digitalization

Tom Copeland is TRAK Chief Technology Officer. During his 40 years with the company, he has seen how job shops can fall behind during technology transitions.

“Most shops are still at step one, getting started with what I call the dashboard era,” Copeland explains. “They are basically connecting machines to software applications, then monitoring those machines from a managerial dashboard. The benefits of this first step are to sort out connectivity

TRAK Chief Technology Officer Tom Copeland says job shops can now make the transition to digitalization because it is adaptable at the operator level. Production-level machines at TRAK enable this by leveraging the Siemens SINUMERIK ONE CNC platform. As TRAK Vice President of Engineering, Leo Gammaitoni stresses the importance of making technology easily adaptable. and security issues along with preparing the organization to make data driven decisions. But then shops need to take the next step. They need to implement software that connects machine tools and shop floor personnel. This provides the targeted information that enables an organization to implement new business models. Together with Siemens, we can help our customers take that next step.”

According to Copeland, Siemens is the right technology partner at the right time, and the reason can be summed up in one word: automation.

“Automation can mean any kind of mechanism that enables a process to go from part-to-part,” Copeland says. “The Siemens SINUMERIK ONE platform enables TRAK and our job shop customers to cross over into that level of automation. We do not need to build our own platforms with all of the related IT and software development. The Siemens platform is already there with their Control to MindSphere® connectivity and their support for common machine protocols like OPC-UA and MTConnect. Also, with the SINUMERIK ONE software development kit and their MindSphere API, TRAK is able to add new features that are targeted at specific markets without us having to write complex software from scratch.

Uplifting Toolrooms and Production

Leo Gammaitoni is TRAK Engineering Manager. He sees the company’s relationship with Siemens as perfectly aligned with TRAK in the delivery of digitally evolved production machines that are easy to adapt at the operator level.

“The Siemens control has long been the closest to what we’re doing in terms of conversational CNC, the ease of use, the ease of programming,” Gammaitoni says. “Our ProtoTRAK controls and machines serve prototyping and low-volume production. But machine shops also need that ease of use on production equipment, and Siemens was the No. 1 choice to partner with to do just that.”

Central to the digitalization strategy at TRAK is the adoption of the SINUMERIK ONE control’s “digital twin”.

This software module, called Create MyVirtual Machine, enables machine motion to be visualized and exactly measured on a 3D plane. The digital twin workspace moves machine design, operation, maintenance, and operator training far beyond the limitations of current simulation software.

“Using Create MyVirtual Machine, I can see the entire machine in exact 3D before the machine is even built,” Gammaitoni says. “I can customize the machine, make changes, and see what happens. I can trace a tool path and be confident that it’s 100 percent accurate.”

Gammaitoni and TRAK plan to collaborate with Siemens to leverage the SINUMERIK ONE CNC platform to create other leaps forward in production-level machining. The integration of more powerful yet intuitive CNC opens the way to building production machines with much faster spindle speeds, improved surface finishes, faster setups, and parts completion. All of which contribute to faster time-to-market.

For example, by exploring within the SINUMERIK ONE CNC digital twin environment, Gammaitoni and his engineers proved that the motion of their new production machines could evolve from traditional linear ball guides to linear roller guides.

“We’ve gone to a more rigid production machine because we proved within the digital twin environment that we could take advantage of that greater rigidity,” Gammaitoni says. “This was also made possible by the Siemens control, which is capable of moving faster and cutting at higher speed rates.” A New Set of Digital Tools Chris Britton feels privileged to have collaborated with the leadership team at TRAK Machine Tools for over 15 years. As the Siemens account manager, he has closely participated in the adoption of digital CNC technology at TRAK. “It was never about selling features and functions,” Britton says. “When we talked about the SINUMERIK ONE A shared vision: Former TRAK Machine Tools owner Rich Leonhard (left) and current owner Steve Pinto (right) see the Siemens SINUMERIK ONE control platform as the company’s way forward in the development of digitally enhanced production machines.

platform and the path to digitalization, we didn’t say, here’s this incremental improvement in hardware with more features. We talked about a digitally enabled platform for job shop business evolution and the software tools to take you there.”

Within the Siemens digital twin design environment of SINUMERIK ONE, a numerically exact 3D tool path accounts for all related forces, including tool type and speed, part material, part shape, and machine rigidity.

Create MyVirtual Machine software enables the machine design engineer to see in 3D exactly how the machine will perform before actually building the machine.

Run MyVirtual Machine enables a job shop to use virtual 3D to dramatically cut part production time, train machine operators, and improve shop-wide processes.

Owning the Challenge

Having found the right technology partner in Siemens, the company that pioneered the ProtoTRAK control for toolrooms everywhere is helping those customers confidently take the next step into digitally enabled production.

“Prototyping and production are different operations requiring different technology solutions,” Pinto says. “TRAK can now offer machine technology solutions across both sides of a customer’s business.”

True to its beginnings, TRAK leadership is seeing to it that the company continues to earn the trust of customers by helping machine shops survive and thrive. Whether you call wvit digitalization, IoT, or Industry 4.0, the way forward for TRAK starts with trust.

A Legacy of Engineering Innovation

TRak Machine Tools will always trace its success back to its down-to-earth beginnings.

starting out as a job shop in 1951, TRak Machine Tools was founded by a former lockheed engineer, Dr. fred Jenks. Under the name southwestern industries, the shop performed contract work for the aerospace industry, but it wasn’t long before its engineering mindset led to the acquisition and perfection of a mechanical marvel called the Trav-a-Dial.

“The Trav-a-Dial is an all-mechanical device that supplements the Vernier dials on a manual machine with precision measurement,” explains steve Pinto, TRak owner and Ceo. “it was wonderfully well-designed, worked beautifully, and we sold over 100,000 of them.”

Most important, the popularity of the Trav-a-Dial established an early connection with toolroom machinists across the country, Pinto says. That connection was strengthened as the company went on to develop digital readouts based on the same gauge-wheel technology. Pinto was the company’s service manager at the time, and he recalls spending many hours visiting customer shops, getting to know people, learning their challenges. Top of mind was the migration of manual production machines to CnC machines. it was a growing challenge that all shops faced, including southwest industries. what toolroom machinists needed was a retrofit CnC that would naturally build on their familiarity with the digital readouts pioneered by southwest industries. Pinto credits Rich leonhard, the company’s owner and leader at the time, for inventing what would become the ProtoTRak—the first retrofit CnC for manual machine tools. a control that would soon prove to be the toolroom machinist’s best friend. leonhard, an engineer, especially understood the toolroom machinist’s need for a CnC that was not only more efficient, but also easy for a toolroom operator to use.

“we worked hard to not make the ProtoTRak look like a computer on a stick,” leonhard recalls. “The people who needed it were skilled but not computer literate. in fact, many were computer-phobic. They didn’t want any part of G-codes.”

The original ProtoTRak CnC looked like an advanced digital readout. kept simple, the control was built to speak the language of the machinist, not the language of a computer coder. leonhard emphasizes that the new control did not require G-codes or M-codes, P-codes or f-codes. it featured a simple menu. it asked you what piece of geometry you wanted to create, and you answered using numbers, doing what you knew how to do. Then you just let the control figure out where to move the table.

“That was the essence of the ProtoTRak CnC when we introduced it in 1984,” leonhard says. “it still is today. it’s the reason why over 50,000 of the systems have been installed across the U.s. and the world. More importantly, it’s the reason why we are on a first-name basis with thousands of machine shops. People we know personally, who can trust us to help them make the move to adaptable, operator-oriented digitalization.”
