The size and shape of the probe selected should be able to access the part while clearing all its features.
TEMPERATURE CAN BE A FACTOR
For critical features with close tolerances, temperature can be a factor. For example, let’s say the part is an axle shaft. The shaft is just under one inch because ultimately, it’ll need to go through a hole in the housing that’s exactly one inch in diameter. If I take a measurement of that shaft when it’s 90 degrees, it might read over one inch but when it cools down it’s under one inch.
The point is, temperature can be a factor that should be considered when investigating in-process gaging.
To ensure consistent readings from part to part, first use the datum sphere to calibrate the probe
INVESTIGATE YOUR OPTIONS
Today we see a trend where more companies are looking for ways they can run lights-out of with fewer workers. In-process gaging can help with the automation that many shops need, but the things I’ve just mentioned should be considered up front. Gaging companies are more than happy to help investigate the options, often alongside the machine tool builder.
