Principles of formulating process routes of CNC lathes in Chinese machine tool factories

The formulation of the CNC turning process route of the Chinese machine tool factory generally follows the principles of rough first and then fine, near and far, internal and external intersection, trace first, minimum program segments, and shortest tool path. In order to achieve high quality and high efficiency And the purpose of Chengmu low.
1. First rough and then refined
For those parts with higher processing quality requirements or more complex parts, in order to improve production efficiency and ensure the best processing quality. Usually, when formulating a processing route, the process route is divided into the following stages:
(1) Rough machining stage. The main task is to remove most of the margin on each surface in a short period of time. The purpose of processing at this stage is mainly to increase productivity.
(2) The semi-finishing stage. Finish the secondary surface processing, and prepare for the finishing processing of the main surface, and try to meet the most uniformity requirements of the finishing processing.
(3) Finishing stage. To ensure that the main tables meet the requirements specified in the drawings, the key is to ensure the processing quality.
