Abstract
A control device includes: a storage unit that stores a working program and a tool length correction amount; a control unit that causes a table and a spindle to relatively move on the basis of the working program and the tool length correction amount; a region setting unit that sets an interference checking region including a tool held by the spindle on the basis of the tool length correction amount; and an interference determination unit that determines whether the interference checking region interferes or not with obstacles in surroundings of the tool in a case in which the tool and the table are caused to relatively move on the basis of the working program and the tool length correction amount.
Claims7
A control device of a machine tool that includes a table to which a workpiece is secured and a spindle that holds a tool, the control device comprising:
- a storage unit that stores a working program and a tool length correction amount;
- a control unit that causes the table and the spindle to relatively move on the basis of the working program and the tool length correction amount;
- a region setting unit that sets an interference checking region including the tool held by the spindle;
- and
- an interference determination unit that determines whether the interference checking region interferes with obstacles in a region surrounding the tool in a case in which the tool and the table are caused to relatively move on the basis of the working program and the tool length correction amount,
- wherein the region setting unit sets the interference checking region on the basis of the tool length correction amount.
A machine tool, comprising:
- a table to which a workpiece is secured;
- a spindle that holds a tool;
- a spindle motor that causes the spindle to rotate about a longitudinal axis of the spindle;
- a feeding motor that causes the table and the spindle to relatively move;
- and
- a control device that controls the spindle motor and the feeding motor, the control device comprising:
- a storage unit that stores a working program and a tool length correction amount;
- a control unit that causes the table and the spindle to relatively move on the basis of the working program and the tool length correction amount;
- a region setting unit that sets an interference checking region including the tool held by the spindle;
- and
- an interference determination unit that determines whether the interference checking region interferes with obstacles in a region surrounding the tool in a case in which the tool and the table are caused to relatively move on the basis of the working program and the tool length correction amount,
- wherein the region setting unit sets the interference checking region on the basis of the tool length correction amount.
