Machining-program generating apparatus, machining-program generating method, and recording medium

A machining-program generating method for generating a machining program to operate a wire electric discharge machining apparatus the machining-program generating method comprising:

• performing via a processor the following steps:
• receiving designation of a part where core fixing machining is performed in a machining shape forming a core;
• dividing, on the basis of content of the received designation, the machining shape into machining shape elements including a first machining shape element for which the core fixing machining is performed and, a second machining shape element for which the core fixing machining is not performed, the second machining shape element being connected to one end of the first machining shape element, and a third machining shape element for which the core fixing machining is not performed, the third machining shale element being connected to the other end of the first machining shape element;
• allocating a first electric condition for the core fixing machining to the first machining shape element and allocating a second electric condition different from the first electric condition to the second and third machining shape elements;
• and
• generating a machining program to machine the second machining shape element under the second electric condition and continuously machine the first machining shape element under the first electric condition after the machining of the second machining shape element, and, thereafter, machine the third machining shape element under the second electric condition, or generating the machining program to machine the second machining shape element under the second electric condition, thereafter, machine the third machining shape element under the second electric condition, and continuously machine the first machining shape element under the first electric condition after the machining of the third machining shape element.

A non-transitory computer-readable recording medium having recorded thereon a plurality of commands for causing a computer to generate a machining program to operate wire a electric discharge machining apparatus, the machining program causing the computer to execute a method comprising:

• receiving designation of a part where core fixing machining is performed in a machining shape forming a core;
• dividing, on the basis of content of the received designation, the machining shape into machining shape elements including a first machining shape element for which the core fixing machining is performed and, a second machining shape element for which the core fixing machining is not performed, the second machining shape element being connected to one end of the first machining shape element, and a third machining shape element for which the core fixing machining is not performed, the third machining shape element being connected to the other end of the first machining shape element;
• allocating a first electric condition for the core fixing machining to the first machining shape element and allocating a second electric condition different from the first electric condition to the second and third machining shape elements;
• and
• generating a machining program to machine the second machining shape element under the second electric condition and continuously machine the first machining shape element under the first electric condition after the machining of the second machining shape element, and, thereafter, machine the third machining shape element under the second electric condition, or generating the machining program to machine the second machining shape element under the second electric condition, thereafter, machine the third machining shape element under the second electric condition, and continuously machine the first machining shape element under the first electric condition after the machining of the third machining shape element.
