After selecting the cnc processing method and dividing process, the main content of the process route is to arrange the processing methods and processing sequence reasonably. The cnc processing steps of the parts usually include a cutting process, a heat treatment process, and an auxiliary process.

The order of these processes directly affects the processing quality, production efficiency and processing costs of the parts. Therefore, when designing the Precision Forging CNC Machining route, the above processing sequence should be reasonably arranged.

Cnc processing sequence arrangement:

(1) First coarse and fine

For example, in the order of roughing, semi-finishing, and finishing, the machining accuracy is gradually increased. In this way, on the one hand, the metal removal rate is increased, and on the other hand, the uniformity requirement of the finishing vehicle is satisfied.

(2) First near and then far

Under normal circumstances, the modern part of the cutting point is processed first, and the part of the cutting point is processed later to shorten the moving distance of the tool and reduce the idle travel time.

(3) Internal and external cross principle

For the Thermostatic CNC Lathe Parts that have both the inner surface and the outer surface to be processed, when the processing sequence is arranged, the inner and outer surfaces should be rough-machined first, and then the inner and outer surfaces should be finished.

(4) Principle of the first and second principles

The main working surface and the mounting base of the part should be machined first, so that early detection of the main surface of the blank may result in modern defects. The secondary surface can be interspersed, placed on the main machined surface to a certain extent, and before final finishing.

(5) First face and back hole principle

The plane profile size of the box and bracket parts is large. Generally, the plane is first processed, and the holes and other dimensions are processed. In this way, the processing sequence is arranged, and on the one hand, the processed plane is positioned to be stable and reliable; on the other hand, it is easy to machine the hole in the processed plane, and the processing precision of the hole can be improved, especially when the hole is drilled, the axis of the hole is not easy.
