【正文】 t stiffness and stability, the structure must be reasonable. As a result of milling and cutting force cutting more and more intermittent cutting edge, easy processing of vibration, so they should pay attention to the design of milling machine fixture: clamping force to be sufficient selflocking and antistroke。Milling fixture design features First, the main types of milling machine fixture and structure of the form Milling fixture for machining parts on the main plane, groove, keyway, spline, and the gap as well as face shape. Usually as a result of milling fixture table together with the feed movement, in different ways according to the feed milling fixture can be divided into straightline feed type, feed circular mode and rely on three types of feedtype. 1. Linear feedtype milling fixture This type of milling machine with the most. Fixture installed in the milling machine table, the processing in a straight line with the feed table by way of movement. According to the workpiece quality, structure and production quantities will be designed as a onepiece fixture points more than the parallel and more than a row followed by clamping of the linkage approach, sometimes the use of subdegree institutions, both to improve production efficiency. 2. Circletype milling machine fixture feed Circle feed milling in the case of nonstop loading and unloading the workpiece, the general is a multitasking, and in the milling machine rotary table use. This fixture is pact and easy to operate, mobile time and auxiliary time overlap is highperformance milling fixture, for use in highvolume production. 3. By mold milling fixture This module depends on the milling machine with a fixture used in dedicated or universal milling machines on the processing of various noncircular surface. On the role of mold is to make access to supplementary motor workpiece to form a profile c
