quality improvement End of the line, in the machine, or no gage at all, each strategy has its own benefi ts


M125 two-axis end-of-line automatic measuring machine incorporates two wide-range plug gages. Originally confi gured to check cylinder bores in a family of two automotive cylinder blocks, the machine can be adapted to other parts within the same architecture.

here is a symbiotic relationship between preci- sion manufacturing and precision metrology. The simple truth is that neither can reach its full


productive potential without the other, and the best so- lutions integrate them as seamlessly as possible. Automotive engine manufacturing offers a valuable insight into this phenomenon and an instructive study of the tradeoffs between the available gaging technologies that can be applied to it. We will use electronic bore gaging as an example, but the lessons apply to other applications as well. What once was the domain of purpose-built special machines is rapidly morphing into a world of fl exible CNC

cells. With that change comes a range of new options for the gages you’ll need to control the process. It’s not a decision to be made casually since each choice carries with it signifi - cantly different capabilities that impact both capital cost and long-term productivity.


Put the Gage at the End of the Line


Employing a single stand-alone station that incorporates special dedicated gages designed specifi cally for the part or part family is the typical solution for automotive applica- tions today. A key advantage of this approach compared to multiple standard in-machine gages is the fact that machine
