Abstract
When die machining including machining processes from a rough machining process to a finish machining process is carried out on the same workpiece along a closed machining path, each of the points equally dividing a length of the closed machining path by the repetition number of machining processes is defined as an approach point, so that the approach points are different from each other for each machining process. This makes it possible to avoid a concentration of the approach points at one points thereby preventing a dent from being formed at the approach point.
Claims15
A method for preparing a program for die machining, said program repeating a plurality of machining processes along a predetermined closed machining path during wire-cut electric discharge machining to thereby machine a workpiece into a die, said method comprises a step of preparing a program for die machining so that approach points, which are machining-start points on the machining path, are different from each other in different machining processes.
An apparatus for preparing a program for die machining used in wire-cut electric discharge machining based on a machining shape input thereto, said apparatus comprising machining path defining means for defining a closed machining path from the machining shape input thereto;
- and program preparing means for preparing a program for die machining, said program repeating a plurality of machining processes along the closed machining path to thereby machine a workpiece into a die, wherein said program preparing means prepares the program so that approach points, which are machining-start points on the machining path, are different from each other in different machining processes.
A computer readable storage medium for storing a program for preparing a program for die machining used in wire-cut electric discharge machining, said program repeating a plurality of machining processes along a predetermined closed machining path to thereby machine a workpiece into a die, said program being prepared so that approach points, which are machining-start points on the machining path, are different from each other in different machine processes.
A method for carrying out die machining by wire-cut electric discharge machining, said method comprises a step of repeating a plurality of machining processes along a predetermined closed machining path so that approach points, which are machining-start points on the closed machining path, are different from each other in different machining processes, thereby machining a workpiece into a die.
