Description: CNC machining in the dividing process, must inspect the structure and manufacturability of the parts, CNC machining center machine, nc machining parts how much content, installation of number and the unit production organization in mastering the condition. The recommended process focus of the original Is still based on the principle of procedure, according to car radiator cap the actual situation to determine, but must be reasonable. The process can generally be divided into according to the following methods:
1, the cutting tool focus points sequence method
This method is according to the classification process of the cutting tool used, with the same finish cutting tool machining parts on all parts can be finished. In order to reduce the tool change time, idle time compression, reduce unnecessary positioning error, method of cutting tool concentration process of the processing of zero.
Thing, that is, in a clamping, as far as possible with a cutting tool used parts of the processing of possible processing, and then change another processing and other parts of a knife. Which can decrease The Times of change knife compression idle time, reduce unnecessary positioning error.
2, with machining parts points sequence method
Each parts of different structural shapes, on the surface of the technical requirements are different, so the processing, the positioning methods each have differences, thus can be divided according to the different way of DIN screw plug positioning process.
Content of many parts for processing, according to the characteristics of its structure, processing part is divided into several parts, such as the shape, shape, surface or plane, etc. General processing plane, positioning surface first, after processing hole; Simple geometric shapes, and then processing complex.
Geometry; Low precision machining parts, and then higher parts machining accuracy requirements.
3, to the rough and finish machining sequence method
According to the parts machining precision, rigidity and deformation factors such as dividing process, can be divided according to the principle of separate rough and finish machining process, namely the roughing and finishing first, at this moment, in different machine or different tools available for processing; For easy to happen.
Deformation of the part, due to the rough machining deformation may occur after the need for school, so in general every to be rough and finish machining of separate processes.
Machining allowance is too big, not only increased machining the amount of labor, reduces the productivity, and increased the cost data, objects, and electricity, CNC machining progress in the capital. If machining allowance is too small, it means less than both dispel all kinds of process Faults and deviation, and this means less compensation process deviation, the clamping form of waste. The extraction rule is under the premise of guarantee quality CNC machining, make allowance for small as far as possible. Generally speaking, the more Magnetic Drain Plug refined, the smaller process allowance.
When determine the CNC processing order, to clear whether the parts to carry on the processing before the first rehearsals. Preparation is often performed by ordinary machine tools. If precision is higher, the blank positioning also relatively reliable, or machining allowance and uniform fully, can need not for rehearsals, and Directly on the CNC machine processing. At this moment, want to consider to CNC machine according to the precision of the blank crude benchmark process, procedure, or into several steps to complete.
