Reculiarities of contour-cutting work of MPCM plate stock in serial production
Contour cutting and punching of MPCM sheets by all applicable methods was done in serial production. The metallographic research of work zones was done by diverse tools and methods: hand shears, hack-saw, file, milling, laser, carving out, and punching. The peculiarities of these kinds of machining at the stage of structural elements production and assembling stage are analyzed. The comparative tests of sample items after guillotine cutting, milling, and laser cutting were conducted. It was observed that the best results are received at milling with sharp-edge finishing.
