Shenyang machine tools are usually the most suitable for adding tool parts.

CNC machining process analysis Whether manual programming or automatic programming, process analysis of the processed parts is required before programming. When programming the process, the programmer needs to have the machine manual, programming manual, cutting dosage table, standard tool, fixture manual and other materials, and select the appropriate machine tool according to the material, contour shape and machining precision of the workpiece to be processed. Determine the processing order of the parts, the tools, fixtures and cutting amounts used in each process, in order to efficiently process qualified parts.

The reasonable selection of machine tools is based on the application practice of CNC machine tool transformation technology at home and abroad, and the applicable scope of CNC machine tool processing. When the accessories are not too complicated and the production batch is not too large, general-purpose machine tools should be used; when the complexity is increased, the CNC machine tools are more suitable. Compared with the production batch, the Fushun machine tool uses three kinds of machine tools to process the comparison of the comprehensive cost. It can be seen from the figure that in the production of multiple varieties and small batches (less than 100 pieces), the use of CNC machine tools can obtain better economic benefits. The increase in the number of parts is unfavorable for the selection of CNC machine tools. In summary, Shenyang machine tools are usually best suited for machining parts with the following characteristics:

(1) Parts in multi-variety, small-volume production or parts in new product trial production.

(2) Parts with complex contour shapes and high requirements for machining accuracy.

(3) When machining with ordinary machine tools, parts of expensive process equipment (tools, fixtures, and molds) are required.

(4) Parts that need to be modified several times.

(5) Expensively expensive parts that are not allowed to be scrapped during processing.

(6) Urgently needed parts requiring the shortest production cycle. 2. The disadvantage of CNC machining: it is a high cost of equipment. Despite this, with the rapid development of high-tech, the popularity of CNC machine tools and the improvement of people's understanding of CNC machine tools, its application range will be increasingly expanded.
