Programming of adaptive machining for end milling

Abstract

The problem of performing adaptive machining to program the milling of the detail contours on the CNC machine in case of virtual-location procurement is solved. The correction of the CNC-program by measuring the actual position of the workpiece on the machine table is proposed, and the correction of the control program can be implemented in the result of solving the task of minimax, when looking for such state of its position in space to the maximum allowance on the machined contour was minimal. A mathematical model is developed that unambiguously identifies the position of the workpiece on the machine table according to the measured coordinates of the three points. The developed algorithms automatically search for the correction of the CNC-program for implementing the principle of adaptive machining solution of the problem of minimax. The soft program is created and the method of designing the CNC-program for a virtual basing of the workpiece on the CNC machine is developed. Experimental testing has confirmed efficiency of the developed technique.
