Study on the Algorithm of Tool Compensation for Rotary Center Offset in 5-Axis Machining
In 5-axis NC machining, if the worktable rotary center or the cutting tool swivel center offset, in program blocks, the cutting tool position will also change and the compensation is needed. The author studies the mathematic relationship among the rotary center offset values, rotary angle A, B and C and the cutting tool position compensation values and designs the computer automatic processing algorithm which can rapidly and accurately calculate the compensation values for position change of the cutting tool and amend the cutting tool position in program blocks so as to obtain a practical NC program.
