SPC Gaging Tips
Statistical Quality Control has been in use since the 1930s, when it was performed with paper, pencil, and maybe a slide rule. As such, it was originally somewhat time consuming, and it required a fairly high level of care and understanding on the part of its practitioners.
By transmitting wirelessly into the machine tool's controller, data can be put to use as part of the calculation for offsetting. Thus, as the operator measures a part, the data is used to assign the proper offsets, greatly improving the quality and throughput of the machine tool.
After all that has been written about Statistical Process Control (SPC) in the past few years, I am continually surprised at how often shop owners tell me they would like to do SPC, but they’re “just too small,” or they “can’t afford all that fancy equipment.”
