Abstract
The invention relates to a numerical control machining method for a thin narrow notch with a thin edge. The notch is 32 mm in depth, and 3 mm in height, and is formed according to the following steps: 1) fixing a part on a tooling clamp; 2), carrying out roughing with a standard disk miller of which the diameter D is 60 mm and the thickness d is 2 mm; 3), carrying out semi-finishing with a standard disk miller of which the diameter D is 60 mm and the thickness d is 2.5 mm; and 4), carrying out finishing on the notch. According to the method, the problem that the size of the notch is extremely poor is solved; and a more reasonable method is provided for the numerical control machining of the whole tooling, so as to ensure high processing precision of the whole tooling and improve the production efficiency.
Description
Technical field
The present invention relates to the numerical-control processing method of the thin narrow notch of a kind of thin edges, belong to a kind of machining process.
Background technology
The design feature of the part of the thin narrow notch of thin edges is point, thin, two sides profile, need turn-over processing, machining benchmark is difficult to determine, the particularly processing of the wide 32mm deep trouth of 3mm mouth, scraps because these factors of processing characteristics of cutting force, cutting output, cutting speed, clamping and lathe itself can cause frock distortion in process.
Summary of the invention
The technical problem to be solved in the present invention is to provide the numerical-control processing method of the thin narrow notch of a kind of thin edges, the method not only efficiently solves notch dimension overproof problem, also the digital control processing of whole frock is proposed to more rational method, make the machining accuracy of integrated tooling high, and improved production efficiency.
For overcoming the above problems, concrete technical scheme of the present invention is as follows: the numerical-control processing method of the thin narrow notch of a kind of thin edges, and the degree of depth of this notch is 32mm, width is 3mm, comprises the following steps:
1) part is fixed on frock clamp;
2) selecting diameter is D=60mm, and the standard plate milling cutter of thickness d=2mm carries out roughing;
2.1) cutting-in 15mm machining accuracy is 0.01mm for the first time, and cutting revolution is 150 to turn, and cutting speed is 50m/min;
2.2) cutting-in 15mm machining accuracy is 0.01mm for the second time, and cutting revolution is 150 to turn, and cutting speed is 50m/min;
2.3) cutting-in 2mm machining accuracy is 0.01mm for the third time, and cutting revolution is 300 to turn, and cutting speed is 80m/min;
3) selecting diameter is D=60mm, and the standard plate milling cutter of thickness d=2.5mm carries out semifinishing;
3.1) cutting-in 15mm machining accuracy is 0.01mm for the first time, and cutting revolution is 150 to turn, and cutting speed is 50m/min;
