The Division Of Cnc Machine Tool Processing Procedures


The division of CNC machining processes can generally be carried out in the following ways.
 

(1) Divide the process according to the positioning method of parts

 
Due to the different structure and shape of each part, the accuracy requirements of each surface are also different, so the processing methods are different. Generally, when machining the shape, the inner cavity is positioned, and when the inner cavity is machined, it is positioned according to the shape, so the process can be divided according to the different positioning methods.
 

(2) Divide the process according to the principle of rough first and then fine

 
In order to improve the productivity and ensure the processing quality of the parts, in the cutting process, the roughing process should be arranged first to remove most of the allowance of the entire part in a short period of time, and at the same time try to meet the allowance uniformity requirements of the finishing. When roughing is completed, semi-finishing and finishing should be arranged next. The purpose of arranging semi-finishing is to use semi-finishing to make the finishing allowance small and uniform when the uniformity of the allowance left after roughing cannot meet the finishing requirements.
 

(3) Divide the process according to the letter of the cutting tool

 
The tool concentration method is to process all the parts that can be machined with one tool as much as possible in one clamping, and then change the tool to process other parts. This method of dividing the process can reduce the number of tool changes, shorten the auxiliary time, and reduce unnecessary positioning errors.
 

(4) Divide the process according to the processing part

 
For the processing part, the plane and positioning surface should be processed first, and then the hole; the simple geometric switch should be processed first, and then the complex geometric shape should be processed first, and then the parts with higher precision should be processed.
In summary, when dividing the process, it must be flexibly grasped according to the structure and craftsmanship of the part, the function of the machine tool, the number of CNC machining content of the part, the number of clamping times and the production organization of the unit. Parts processing adopts the principle of process concentration or the principle of process dispersion, which should be determined according to the actual situation, but it must be reasonable.
