Tool management digitalization

Having the right cutting tool for a job does not help get the job done if a manufacturer does not know that it has the tool. That sometimes occurred at the Athens, Alabama, production facility of Intech, a manufacturer of medical devices and equipment, said Joseph Forsyth, director of advanced manufacturing at Intech.

“If you don’t know what tools you have for sure,” he said, “then you’re not really going to have a clear understanding of what you can do.”

Having managed the shop floor, Forsyth said he was familiar with almost all the machining tasks performed at the plant.

“I understand every struggle right down to the very floor level,” he said.

After trying numerous solutions to fix even some of the simplest problems, Forsyth said the shop achieved small successes “but nothing that ever really came all together.”

A number of years ago, Intech bought a tool presetter from Zoller Inc. in Ann Arbor, Michigan, after he visited the French parent company following its purchase of Turner Medical Inc., the business he was working for.”When I was introduced to the Zoller system and the software, I didn’t really understand it at the time,” Forsyth said. “But I just knew that the older gentlemen I met in France knew their stuff, and if they’re on to something, then you might want to pay attention. We bought a presetter first, thinking that was all we really needed.”Realizing that Intech was getting only a small sample of what was possible with the presetter, he started researching tool management systems to compare them with the Zoller TMS but found they all were based on software.”Anything that competes with Zoller TMS doesn’t have any well-integrated hardware solutions to go along with it,” Forsyth said.Intech purchased the Zoller TMS with the Gold software package to have the necessary capabilities. With the system in place, he said the medical manufacturer needed to decide how to begin the system integration process.”All of it was there,” Forsyth said, “but you can’t use it all at once. It’s just too expansive.”He said basic development began in the first quarter of 2022, with training key users, developing nomenclature and establishing group structures for all the modules. The TMS timeline for the second quarter primarily covered cataloging single components, or tools, as well as some accessories and fixtures.Forsyth explained that Intech did a complete build of a small sample project to confirm the logic that the shop was using. With the logic established, the company started building all its single components over a four- or five-month period.”Two guys just sitting there creating tool by tool,” he said.Brandon Posey (left), an Intech programmer, and Joseph Forsyth, director of advanced manufacturing, use a Zoller »venturion 450« presetting and measuring machine at Intech’s production facility.

Intech’s timeline for implementing TMS is based on quarters, but Forsyth said some of the broad milestones that he wanted to achieve have been accomplished sooner than expected while others have not.

“Those changed pretty significantly as we moved through the months due to unforeseen changes in the shop or work changes or new things we learned,” he said. “You pick a path, and sometimes you have to bob and weave to find your way.”

In addition, during the second quarter the company received two Kardex Remstar Shuttle XP 500 vertical lift modules to organize the shop floor by enabling high-density storage of supplies in a minimal footprint and prioritizing items that consume the most space.

“It was just getting out of control,” Forsyth said. “Our shop had gotten worse than we realized.”

During the third quarter, Intech started moving inventory into the Kardex modules and assigning locations in tandem with ongoing data creation. In the fourth quarter, the company set up the ordering functions of TMS and the reporting module.

The major milestone that Intech accomplished after the first year, Forsyth said, was to make the old hardware and software system at the shop obsolete.

“I wanted it out,” he said, “and I wanted to be in TMS fully by the end of the first year.”
