Abstract
This invention relates to a control apparatus for numerical control in a cutting machine having a turret which can be rotated to arbitrary positions, and characterized by including means for obtaining turret axis data (ΔX, ΔZ) from reference offset values (X0, Z0) corresponding to a length from a cutting edge to a turret axis B, turret angle data α, and cutting edge data (m, n), and moving the turret on the basis of these turret axis data (ΔX, ΔZ) to perform a cutting.
Claims7
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 (X0, Z0) corresponding to a length from said cutting edge to a turret axis (B);
- means for obtaining offset data (xα, Zα) from said reference offset values (X0, Z0) and said turret angle data (α);
- 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.
A cutting method employing a cutting machine having a turret to be rotated to arbitrary positions, comprising the steps of;
- inputting cutting edge data (m, n) and turret angle data α;
- reading reference offset values (X0, Z0);
- calculating offset data (Xα, Zα) from said turret angle data (α) and said reference offset values (X0, Z0);
- calculating turret axis data (ΔX, ΔZ) from said offset data (Xα, Zα) and said cutting edge data (m, n);
- and
- performing a cutting on the basis of said turret axis data (ΔX, ΔZ).
