[0002] A fixture is a device used to fix the workpiece in the mechanical manufacturing process so that it occupies the correct position for construction or inspection. It is also called a fixture. In a broad sense, any device used to quickly, conveniently and safely install the workpiece in any process can be called a fixture. However, at present, the milling surface processing still uses a vise clamp for manual clamping. However, if the number is large, it is still necessary to design a special fixture to improve efficiency and accuracy. Therefore, a special fixture for milling the surface of the part is proposed.
