Abstract
A method for restarting a tool on a workpiece contour in a numerically controlled processing machine of the type having a display unit for alphanumerical and/or graphical representation of processing information. After a program interruption, the program is executed anew in a control mode without machine movement from a predetermined starting point, and the resulting workpiece contour is continuously, graphically represented on the display unit. The operator utilizes this graphic display to determine an end point of the control mode program execution. The machine is then transferred into its axial positions and its function state to the program state of the end point, and the processing program with machine movements is continued from this end point, thereby starting the tool onto the desired tool path.
