Abstract
A numerical control apparatus includes a command argument determination unit which determines whether a vector is included in an argument of a circular arc interpolation command which is included in command data and a circular arc shape forming unit which forms a circular arc shape based on a machining program, and a start point, an end point, and the vector, which are specified by the argument of the circular arc interpolation command, when the command argument determination unit determines that the vector is included in the argument of the circular arc interpolation command.
Claims3
A numerical control. apparatus which enables specification of a movement trajectory of a circular arc shape by a circular arc interpolation command which is included in a machining program, comprising:
- a program analysis unit which analyzes the machining program so as to acquire command data;
- a command argument determination unit which determines whether a vector is included in an argument of the circular arc interpolation command which is included in the command data;
- a circular arc shape forming unit which forms a circular arc shape based on the machining program, and a start point, an end point, and the vector, the start point, the end point, and the vector being specified by the argument of the circular arc interpolation command, when the command argument determination unit determines that the vector is included in the argument of the circular arc interpolation command;
- and
- a tool trajectory forming unit which forms a tool trajectory based on the circular arc shape.
