Establishment of CNC processing route

In the field of mechanical processing industry, the reasonable processing technology should be selected for the machining process of mechanical parts in order to produce and process more efficiently and accurately. Before the machining of mechanical parts, how to better reflect the efficient and accurate machining quality? Let’s take a look at the formulation of the machining process route of mechanical parts

Now we have a simple understanding of the formulation of the processing route of mechanical parts, which is mainly divided into three steps:

  1. Draw up the processing route: analyze and study the contents and technical requirements of parts production drawings, draw up the processing method, processing scheme and process route of parts processing.
  2. Arrange the processing procedure

(1) Select blank( 2) Arrange machining procedure 1, select machining scheme 2 and determine datum plane reasonably( 3) Arrange the heat treatment process 1. The heat treatment process to improve the cutting performance of metal materials, such as annealing and normalizing, is generally arranged before rough machining. 2. The heat treatment process to eliminate internal stress, such as intermediate annealing, tempering and aging, is generally arranged before rough machining and rough machining. 3. The heat treatment process to improve the performance of mechanical parts, such as quenching, tempering and aging Quenching and tempering, carburizing and other surface treatment are generally arranged before the final processing. All the heat treatment processes are carried out before the final processing of the parts, because the parts must change after the heat treatment process, and the errors caused by deformation can be corrected during the final processing( 4) Arrange the inspection process well. During the production and processing of small batch parts, self inspection, mutual inspection and special inspection shall be carried out. The products can only be delivered after passing the inspection.

  1. Draw up the processing technology process: the purpose of making the processing technology route is to ensure the product quality and improve the economic benefits. At the same time, it is to determine the number of production personnel and select the processing equipment. The principle of processing sequence arrangement: base surface first, rough and fine separation, rough and fine first, surface first and hole second.

Mechanical parts processing technology requirements are different, according to the requirements to choose a reasonable processing route. For precision parts with special requirements, select the precise processing route.
