How to write macro program for machining spherical surface with end milling cutter?
From the processing, finishing the surface of the ball, if the radial line processing, distribution of tool path on the spherical surface is not uniform, near the center spacing is too close, while the surrounding is relatively sparse, the processing effect is not ideal, and if you choose the high level around the way processing.Is the situation does not exist, relatively speaking, a relatively ideal processing effect, so the choice of the spherical tool path can be set in terms of #3 as independent variable angle around the level of processing variables, #3 each increment for the variable #17, which is to the processing of the arc section (usually choose the XZ plane) are divided into several segments.If each section of the corresponding center angle #17=, [#4-#3]/50=[, theta - theta 0]/50, that is, the central angle is divided into 50 segments, in order to improve its processing quality, in the set angle increment (#17) can be smaller, can be more than a few segments.
Take milling of a convex hemisphere with a radius of 15, and tool diameter 10, for example:M3S2000G54G40G90G00X10.Y-20.Z10.#1=0WH[#1LE90]DO1#2=15*SIN[#1]-15#3=15*COS[#1]+5G01Y[-#3]Z#2F300G02J#3F1500#1=#1+1END1G00Z100M30That's all right.Note: the iOS system cannot be pictured above.
