<p>The system is adapted to smooth a flat surface machined by a clamp profiling operation, and improve the clamp profiling stability, by reducing the profiling feed rate before the clamping starting position. This system is provided with a means (KB) for inputting the profiling operation-regulating data including a clamping starting position and a deceleration width set before the clamping starting position, a memory (MEM) for storing the data from the input means (KB), mechanical position-detecting means (PCX, PCY, PCZ, CNTX, CNTY, CNTZ), and means (CPU, CLP, GC) for reducing the profiling feed rate when a stylus (ST) in a tracer head (TR) enters the deceleration width, which is stored in the memory (MEM), and stopping the profiling feed when the stylus (ST) reaches the clamping starting position, to start the clamping feed, on the basis of the stored data in the memory (MEM) and the results of the detection carried out by the mechanical position-detecting means (PCX, PCY, PCZ, CNTX, CNTY, CNTZ). The control system provided with these parts enables a flat surface machined by a clamp profiling operation to be smoothed, and the clamp profiling stability to be improved.</p> |
