Abstract
In one embodiment, a method of and apparatus for determining calibration options in a motion control system is provided. The method includes the steps of measuring error in a commanded motion, modeling the error, identifying sources of the error; and predicting a degree to which applying compensation for one of the sources of the error might affect the error.
Claims7
A method of determining calibration options in a motion control system using the motion control system comprising the acts of:
- a) measuring error in a commanded motion;
- b) modeling the error;
- c) identifying sources of the error;
- and
- d) predicting a degree to which applying compensation for one of the sources of the error might affect the error;
- e) providing a diagnostics interface displaying the sources of error and an indication of the degree to which applying compensation for a respective one of the sources of error might affect the error.
A computer readable medium comprising instructions capable of implementing a method of determining calibration options in a motion control system using the motion control system, the method comprising:
- a) measuring error in a commanded motion;
- b) modeling the error;
- c) identifying sources of the error;
- d) predicting a degree to which applying compensation for one of the sources of the error might affect the error;
- and
- e) providing a diagnostic interface displaying the sources of error and an indication of the degree to which applying compensation for a respective one of the sources of error might affect the error.
A machine tool, comprising:
- a) an actuator having an attached mechanical member;
- b) a motion command generator adapted to produce motion commands capable of controlling the actuator;
- c) a compensator adapted to compensate the motion commands based upon at least one compensation parameter;
- and
- d) a controller in communication with the actuator, the motion command generator, and the compensator, and adapted to:
- i) measure error in a commanded motion;
- ii) model the error;
- iii) identify sources of the error;
- iv) predict a degree to which applying compensation for one of the sources of the error might affect the error;
- v) providing a diagnostic interface displaying the sources of error and an indication of the decree to which applying compensation for a respective one of the sources of error might affect the error.
