The following points should be paid attention to when designing CNC machine tool fixtures:
1. The origin (tool setting point) should be set on the CNC machine tool fixture.
2. CNC machine tool fixtures do not require tool guides. This is because during CNC machining, the machine tool, fixture, tool and workpiece always maintain a strict coordinate relationship, and there is no need for guiding elements between the tool and the workpiece to determine the position.
3. CNC machine tools often need to process workpieces in several directions, so CNC machine tool fixtures should be open.
4. Adjustable fixtures, assembled fixtures and combined fixtures should be used as far as possible on CNC machine tools. Because workpieces processed on CNC machine tools are often produced in small batches of single pieces, fixtures with good flexibility and short preparation time must be used.
5. The clamping of CNC machine tool fixtures should be firm, reliable and easy to operate. The position of the clamping element should be fixed to prevent the element from colliding with the tool during automatic machining.
