Abstract
A method for compensating a profiling direction of a profiling machine which is constructed to effect the surface profiling in any angular direction includes calculating a distance or a deviation quantity between an ideal profiling locus defined from a given profiling angle and an actual machine position and adding a correction angle proportional to the deviation quantity to the given profiling angle to obtain a new profiling angle so that the new profiling angle is used to correct an angle to attain the profiling operation.
Claims3
In a method of controlling a profiling machine including:
- a tracer head capable of tracing an original model and for supplying a displacement signal detected by a stylus to a profiling velocity control unit;
- a servo system including a drive system for driving the profiling machine on the basis of a profiling velocity command signal produced from the control unit, a detector for detecting a position of the profiling machine and a machine position counter for integrating an output signal of the detector to supply the integrated signal to the control unit;
- and
- a control unit for calculating the profiling velocity command signal on the basis of the displacement signals for three axes and an output of the counter to supply the command signal to the drive system;
- a method of correcting a profiling direction of the profiling machine, comprising steps of:
- calculating a distance between a current position of the machine obtained by tracing the model in a plane of axes x and y and an ideal profiling locus in the plane of axes x and y defined by a given profile angle;
- calculating a correction quantity in a moving direction of the profiling machine in the plane of axes x and y on the basis of the distance;
- and
- supplying a velocity command signal on the basis of a corrected moving direction to the servo system from the control unit.
