Cutting and milling methods and techniques commonly used in automobile die processing

Date of release:2018-06-07 Author: Click:

At present, the processing parameters of high speed automobile die for individual enterprises have been used for 30 thousand rotation of the speed of step distance 0.1mm, but for the automobile die, the high speed machining is only suitable for flat outer panel processing, because the higher the speed, the greater the range of the tool line speed, and the cutting speed range allowed by the tool is far less than that. The way to solve this problem is to divide the flat area into separate processing. In order to avoid the shortcoming of the center line speed of the tool, it can be properly obliquity.


The outer panel, such as the drawing die of the engine hood, the automobile die part is slow and can be processed at high speed. The supplement part of the process is not suitable for high speed machining. The inner plate can hardly find the flat surface except the press surface. The flat surface must be large, if it is too small, the cutting tool is too many and the tool path is very short. But frequent turning is not conducive to high speed processing. Even the outer panel can not be separated a bit, such as the front, less surface, less flat area, the drawing die can be divided into high speed processing area less than 20%, this 20% can improve the efficiency of 30%, then the whole punch increase efficiency is above 5%, like the engine hood door and other parts to be higher. Up to 20%. If a part can only be separated from a small piece to be processed at high speed, it will not necessarily increase efficiency for the whole.


The commonly used cutting and milling methods in automobile die processing are mainly as follows:


1. High incoming milling method (features: small cutting depth AP, high FZ, high Vc).


2. High speed milling (features: small cutting width AE, large cut AP, more wearable material cutting tool, low cutting heat, dry cutting).


3. Plunge milling method (features: high metal removal rate, large allowance and long overhang).


4, "slice" milling method (features: small cut width AE, large cut depth AP, high Vc, spiral cutting edge design). In addition, the cycloid milling method is also a kind of machining method similar to the "slice" milling method.
