Method of automatically determining a machining range for lathe turning machining and an automatic programming system for lathes

摘要

In the present invention, a machining range for each chucking can be determined automatically by inputting a final work shape and a starting material shape. Therefore, the burden on the operator can be reduced. That is, the present invention is a method for automatically determining a machining range, comprising the step of inputting a final work shape and a starting material shape for a lathe turning machining operation and automatically collectively determining one or more chucking places and corresponding lathe turning machining ranges which will result in the production the desired final work shape. Further, the present invention is an automatic programming system for controlling lathes, comprising a machining range determination portion that collectively determines one or more chucking places and corresponding lathe turning machining ranges, which will result in the production of the desired final work shape, on the basis of the final work shape and the starting material shape.
