Most wood workers do in process inspection; i.e. are the dados the correct width to fit the shelf, do the dowels hole line up, are these two boards the same length and width, etc.!

But when those checks don’t yield the proper results or if the in process is done too late and mistakes are found can the proper corrective action be applied or is a design change possible/required?

I worked in manufacturing engineering at several companies and they required scheduled calibration of tools from calipers to diamond drill bits for drilling laser guide tubes. If tools are out of calibration the tool cannot be used until it is calibrated. I don’t do that in my shop because I am the only one that uses these tools as I am responsible for the work they produce and rely on in process inspection to catch these errors.
