Abstract
In a gear cutting simulation method and device, a gear-cutting-machine model which specifies relative positions between a blank model and a cutter model is created. A gear model is created as a result of simulation of gear cutting which is performed with the blank model and the cutter model arranged in the gear-cutting-machine model.
Claims8
A gear cutting simulation method comprising the steps of:
- creating, in a gear cutting simulation device, a gear-cutting-machine model which specifies relative positions between a blank model and a cutter model;
- creating a gear model as a result of simulation of gear cutting performed with the blank model and the cutter model arranged in the gear-cutting-machine model;
- outputting data indicating a tooth-contact state as a result of tooth-contact simulation performed by changing the relative positions between portions of the gear model which are arranged in an assembled state with one another;
- and comparing the outputted data indicating the tooth-contact state with a predetermined reference value, so that validity of the gear model is determined by the comparison result.
A computer program product, embodied on a computer readable medium, for causing a computer to execute a gear cutting simulation method, the method comprising the steps of:
- creating a gear-cutting-machine model which specifies relative positions between a blank model and a cutter model;
- creating a gear model as a result of simulation of gear cutting performed with the blank model and the cutter model arranged in the gear-cutting-machine model;
- outputting data indicating a tooth-contact state as a result of tooth-contact simulation performed by changing the relative positions between portions of the gear model which are arranged in an assembled state with one another;
- and
- comparing the outputted data indicating the tooth-contact state with a predetermined reference value, so that validity of the gear model is determined by the comparison result.
A gear cutting simulation device which causes a computer to execute a gear cutting simulation method, comprising:

- a gear cutting simulation unit configured to create a gear model as a result of simulation of gear cutting performed with the blank model and the cutter model arranged in the gear-cutting-machine model;
- a tooth-contact simulation unit configured to output data indicating a tooth-contact state as a result of tooth-contact simulation performed by changing the relative positions between portions of the gear model which are arranged in an assembled state with one another;
- and
- a determination unit configured to compare the outputted data indicating the tooth-contact state with a predetermined reference value, so that validity of the gear model is determined by the comparison result.
