Jig or template to hold a workpiece?

Question

Technical English for a foreigner - please correct and rephrase if you can come up with better alternatives. > A machine in manufacturing usually is fed material or a workpiece to be processed. Sometimes, the orientation of the workpiece [synonyms?] is defined by a kind of jig into which the workpiece is inserted. Is there a better word for _jig_?

Answer 1

No. Anyone who knows any engineering, woodworking, metalworking, etc., knows what a jig is.
