Description

technical field

[0001] The invention relates to a method for controlling the concave-convex pattern on the surface of a workpiece, in particular to a method for controlling the concave-convex pattern on the surface of the workpiece when a ball-end milling cutter is used, and belongs to the field of mechanical processing technology. Background technique

[0002] In CNC milling, in order to improve the processing efficiency, while continuously increasing the spindle speed, the feed rate is also continuously increased, that is, the feed rate per revolution of the spindle is increased (hereinafter referred to as the feed rate per spindle revolution) as "feed rate"). The feed rate used in cutting abroad sometimes even reaches 0.4-0.5 mm / rev. After literature search, it was found that Zhao Minming and others wrote an article in "Journal of the Society of Precision Engineering" (Japan), 1998, 64 (12) 1826-1830, "5-axis Yuboyiruendomiru machining ni γŠγ‘γ‚‹ surface roughness generation...
