Do I need dedicated fixtures?

It depends on part geometry and locating requirements. Regular, flat, orientation-independent parts usually need only a simple locating block, which is cheap and quick to change over. Irregular or rolling parts, parts needing multi-face measurement, and cases where repeat locating accuracy must approach the equipment's own repeatability call for a dedicated fixture, otherwise locating error eats directly into the measurement margin. Fixtures can be built in-house or designed and manufactured by us; determine this during the trial stage so you do not discover handling problems only after the machine arrives.
