Article 20 CNC machining programming skills, it is experience

More white steel knife revolutions do not too fast. Use less copper on thick white steel knife, multi-purpose fly knife knife or alloy. When workpiece is too high, should be layered with different lengths of thick knife open. After opening coarse with broadsword, used a knife to remove excess stock, ensure consistent allowance to laser scalpel. Graphic application flat-bottomed cutter machining, using less spher mill processing, in order to reduce processing time. Copper industry Angle, first check R Angle size, to determine how spher mill. The school table plane four edges to gong ping. Slope is an integer, application of slope knife processing, such as tube. Do each working procedure before, want to clear before the rest of the procedure, after processing allowance, prevent to avoid excessive air knife processing. As far as possible simple cutter path, such as appearance, chamfer, and single, walk around the contour. Go when WCUT, can FINISH, we don't go ROUGN. When shape feeding, coarse light first, then off, workpiece raise, optical margin first, to the bottom of the light. 。 Setting up reasonable tolerance to balance the processing precision and computing time. A coarse, 1/5 of the tolerance as allowance, laser scalpel, tolerance to 0. 01. 14. Do more working procedure, reducing the time of air knife. Do more thinking, reduce the error chance. Do more auxiliary line auxiliary plane, improve processing conditions. 15. Milling plane, multi-purpose spher mill, less with the knife, don't be afraid of the knife. 16. A knife Angle, broadsword refinement. 17. Don't be afraid to face, the appropriate surface can improve the processing speed and beautify the processing effect. 18. Blank material hardness: conventional milling is better. 19. Blank material hardness low: climb milling is better. 20. Machine tool precision, good rigidity, finishing: suitable for milling, whereas the adaptive inverse milling.
