Abstract
A machining time prediction system divides a machining program to be executed by a machine tool into a plurality of sections, transfers the divided machining programs to arithmetic unit to calculate machining times and integrates the calculated machining times. Thus, when hardware resources of an arithmetic processing apparatus for calculating a machining time are lacking, it is possible to perform necessary calculations in cooperation with the other management apparatus or machine tool or the like, and thereby shorten a processing time.
Claims8
A machining time prediction system that predicts a machining time, comprising:
- a machining program dividing unit for dividing a machining program executed by a machine tool into a plurality of sections;
- a machining program transfer unit for transferring the divided machining programs to at least one arithmetic unit;
- a machining time receiving unit for receiving the machining time calculated by the arithmetic unit;
- and
- a machining time integrating unit for integrating the machining time received by the machining time receiving unit,
- wherein the machining program dividing unit divides the machining program in a manner such that parts of divided sections before and after the dividing position partially overlap, and
- the machining time integrating unit integrates machining times received by the machining time receiving unit, and then subtracts the machining time of the overlapping parts.
