Abstract
A control device includes: a control unit configured to control a main processing machine by replacing a machining shape on a machining surface of a workpiece specified in a program with a shape corresponding to an enlargement/reduction ratio and replacing a fixing distance for a core specified in the program with a distance corresponding to the enlargement/reduction ratio for the machining shape of the workpiece and a plate thickness ratio between the workpieces.
Claims10
A control device for controlling a main processing machine in accordance with a program where a plate thickness of a workpiece is a first plate thickness, comprising:
- a program storage unit configured to store a program for specifying a machining shape on a machining surface of the workpiece and a fixing distance of a fixing portion that fixes a core to be formed by machining the workpiece to the workpiece, on a machining line between the workpiece and the core;
- an enlargement/reduction ratio setter configured to set an enlargement/reduction ratio of the machining shape of the workpiece;
- a plate thickness setter configured to set a second plate thickness as the plate thickness of the workpiece to be machined by the main processing machine;
- a plate thickness ratio calculator configured to calculate the ratio of the second plate thickness to the first plate thickness as a plate thickness ratio;
- and
- a control unit configured to control the main processing machine by reading the program replacing the machining shape specified in the program with a shape corresponding to the enlargement/reduction ratio and replacing the fixing distance specified in the program with a distance corresponding to the enlargement/reduction ratio and the plate thickness ratio.
A program editing apparatus for editing a program where a plate thickness of a workpiece is a first plate thickness, comprising:
- a program storage unit configured to store a program for specifying a machining shape on a machining surface of the workpiece and a fixing distance of a fixing portion that fixes a core to be formed by machining the workpiece to the workpiece, on a machining line between the workpiece and the core;
- an enlargement/reduction ratio setter configured to set an enlargement/reduction ratio of the machining shape of the workpiece;
- a plate thickness setter configured to set a second plate thickness as the plate thickness of the workpiece;
- a plate thickness ratio calculator configured to calculate a ratio of the second plate thickness to the first plate thickness as a plate thickness ratio;
- and
- a program editing unit configured to edit the program replacing the machining shape specified in the program with a shape corresponding to the enlargement/reduction ratio and replacing the fixing distance specified in the program with a distance corresponding to the enlargement/reduction ratio and the plate thickness ratio.
A control method for controlling a main processing machine in accordance with a program where a plate thickness of a workpiece is a first plate thickness, the program specifying a machining shape on a machining surface of the workpiece and a fixing distance of a fixing portion that fixes a core to be formed by machining the workpiece to the workpiece, on a machining line between the workpiece and the core,
- the control method comprising the steps of:
- setting an enlargement/reduction ratio of the machining shape of the workpiece;
- setting a second plate thickness as the plate thickness of the workpiece to be processed by the main processing machine;
- calculating a ratio of the second plate thickness to the first plate thickness as a plate thickness ratio;
- and
- controlling the main processing machine by replacing the machining shape specified in the program with a shape corresponding to the enlargement/reduction ratio and replacing the fixing distance specified in the program with a distance corresponding to the enlargement/reduction ratio and the plate thickness ratio.
