Fixed Scroll Gaging Station

An air conditioning manufacturer produced its fixed sections of scroll compressors on modern CNC machine tools. The machines were performing well, but it was difficult to calculate tool wear. Worn tools continuing to cut parts made scrap. Out-of-tolerance conditions were gradual and unpredictable.

Edmunds Gages designed and built a manual gage featuring our CAG microprocessor readout that analyzes measurements, detects tool wear trends, and directs the CNC machine to make cutter offsets — all automatically. The gage accommodates two current workpiece sizes with space for a third. Three dimensions of the workpiece are measured statically and simultaneously — the primary outside diameter, the seal ring offset step, and the bottom pilot diameter.

Our customer is experiencing improved part quality achieved in a cost effective way. The CAG makes the decision about tool wear trends, which is always consistent, eliminating operator subjectivity.
