Abstract
A numerical controller corrects a tool compensation value for a machine tool provided with a tool for machining a workpiece based on an NC machining program. The numerical controller makes it unnecessary for a person in charge of input to be conscious of the sign of the tool compensation value and prevents a tool compensation value input error by providing an input button for bringing a workpiece and a tool cutting edge close to each other by a specified amount (+input advance) and an input button for causing the workpiece and the tool cutting edge to be away from each other by a specified amount (+input retreat) at the time of inputting the tool compensation value.
Claims6
A numerical controller correcting a tool compensation value for a machine tool provided with a tool for machining a workpiece based on an NC machining program, the numerical controller comprising:
- a tool compensation value setting screen for accepting an input value for correction of the tool compensation value;
- a tool compensation value input unit accepting an instruction for a correction direction of a cutting edge of the tool as seen from the workpiece;
- and
- a tool compensation value input control unit correcting the tool compensation value with the input value for correction, accepted on the tool compensation value setting screen, based on the correction direction of the cutting edge of the tool as seen from the workpiece, the correction direction being accepted by the tool compensation value input unit.
