A typical project for ARC Specialties begins when a customer goes to the company with a manufacturing problem. Working with the customer, the staff will propose a solution. In some cases, ARC needs to prototype the system before a complete proposal is possible. In the ARC research facility, a full testing and technical setup allows the technology services staff to work with tools from stereo lithography welding systems to racecar camshaft welds. Frequently, this ability to develop a process before a full-blown manufacturing system is built will allow ARC to improve the final machine and shorten the delivery time. ARC Specialties builds on three basic platforms, programmable logic controllers (PLC), machine tool controller (CNC) and 6 axis robots. The ARC6 robotic welding robot is one of the last remaining robots designed and build in the USA. No one technology solves all manufacturing problems. Generally ARC will choose a PLC if given a process problem. PLCs are fast and reliable—when the motion requirements exceed that of a PLC, ARC selects a CNC controller. When ARC is presented with a problem that requires 6 axes of motion, the company will use an articulated arm.

ARC Specialties: Force Sensitive Polishing System

POSTED 03/17/2020

The Kuka LBR iiwa is a seven-axis force-controlled collaborative robot (cobot) that incorporates force sensors into each axis with a resolution of less than one pound of force. Combining superior 3M abrasives with BurrKing belt sanders and polishing spindles, along with an experienced robot integrator that puts it all together and creates the code, the result is a cell that demonstrates force-controlled polishing on the belt sander slack side and wheel, with final finishing on a disk.
