Sensor Excellence at Tower AutomotiveOctober 1, 2011
Sensor-applications specialists John Moore and Matt Reynolds test sensors in the Tower Automotive error-proofing laboratory.
It all starts with an unwavering plant-management commitment, spearheaded by plant manager Shawn Callahan and his managerial and technical staffs. Callahan appointed two full-time people to serve as sensor-application specialists, tasked with developing an error-proofing laboratory. They meet weekly with an error-proofing technology committee and to implement, along with the assistance of the toolroom and tool-engineering departments, electronic sensors throughout the plant’s numerous existing and future progressive and transfer tools.

The plant’s sensor-applications specialists: John Moore, a 21-yr. veteran of the tool-and-die-making profession with Journeyman Toolmaker credentials and an Associates Degree in Machine Tool Technology; and Matthew Reynolds, a graduate of the Tower Tool and Die Apprenticeship Program and who also boasts an Associates Degree in Machine Tool Technology, along with an Associates Degree in Business Management. Moore, Reynolds and their team began their die-sensoring efforts by focusing on a transfer tool with more than two dozen sensors located throughout the upper and lower sections. The sensors ensure that, among other monitored events, parts are placed properly on lifters before the press is allowed to close. Previously, the tooling would all-too-often mash parts and/or crash the sections where the parts—once released by the transfer mechanism—did not land on their assigned lifters and/or did not properly nest within the lower sections. Since adding the sensors, the transfer tooling runs faster and unattended, as the operator no longer needs to nervously patrol the process.

A key to the sensor-program’s success is the thorough bench testing of sensors in the error-proofing laboratory. The days of testing sensors only on the shop floor during production runs are over at this facility. And, Moore and Reynolds work closely with the plant’s die engineers to ensure that appropriate wiring channels and mounting details are designed into new tooling, rather than implementing sensors as an afterthought.During one of my visits with this exemplary company, I was struck by the positive attitude exhibited by the press operator as she watched a set of tooling run under the full protection of electronic sensors. What could be more satisfying to the operators on the shop floor, as well as to those in upper management, than to witness smooth-running presses and tooling? MF
