摘要： A numerical contouring control capable of backing up along the path commanded by the block of data controlling the machine tool. When the control is in the backup mode of operation, the counting direction of the X and Y integrand counters of the contouring function generator and the direction control signals for the X and Y motion commands are reversed so that the machine tool reverses its direction along the commanded path. The counting direction of the X and Y distance counters is also reversed in the backup mode so that the X and Y distance counters continue to keep track of the X and Y distances from the present commanded position to the end point of the commanded path. The backup mode is manually terminated by the operator or is automatically terminated when the machine tool reaches the beginning of the commanded path. When the machine tool is returned to the normal mode of operation, the machine tool retraces and completes the commanded path.
