Abstract:
1. A control apparatus for numerical control in a cutting machine having a turret to be rotated to arbitrary positions, said control apparatus comprising: means for inputting cutting edge data (m, n) indicating a position of a cutting edge of a cutting tool; means for inputting turret angle data (α) indicating an extent of rotation of said turret; means for reading reference offset values (X means for obtaining offset data (xα, Zα) from said reference offset values (X means for adding said cutting edge data (m, n) to said offset data (Xα, Zα) to obtain turret axis data (ΔX, ΔZ); and means for moving said turret on the basis of said turret axis data (ΔX, ΔZ) to perform a cutting.
