<p>In a numerically controlled machine tool including a scale, a scanning unit, and a programmable controller a switch is provided to designate the tool correction to be applied to compensate for variations in tool dimensions. This switch has a first position, in which the controller is directed to lengthen the tool path length by an amount corresponding to the tool correction, a second position, in which the controller is directed to shorten the tool path length by an amount corresponding to the tool correction, and a third position, in which the controller is directed to apply no tool corrections to the tool path length.</p> |
