Design Principles of Jig and Fixture:
- The method of location and clamping should be such as to reduce idle time to a minimum.
- The basic principles for good clamping design are:
- The process of loading and unloading the component should be as easy as possible.
- Work supports:
- Stability and Rigidity:
- Clearance of chips.
What is a jig & fixture and what is it used for?
