| Abstract: | The tool compensation function is one oftheimportant functions in precision macmningby the modern CNC system,By employing the principle of vector computation,the doubleprecision floating-point number and structural variables in C language are used to describethe unit vector in the direction of motion,the tool radius vector,theintersection vector.etc.Anew method for linear-transitive double-precision tool compensation based on the principleof analytic geometry is proposed.It has the advantage of high accuracy and execution speed. |
