Title:
TANGENTIAL DIRECTION CONTROL SYSTEM FOR TOOL AXIS
Document Type and Number:
Japanese Patent JPH05324047
Kind Code:
A
Abstract:
PURPOSE:To control a tool so as to always direct it toward a tangential direction corresponding to the advancing direction. CONSTITUTION:A pulse distributing means 61 of a CNC 6 performs pulse distribution processing for designated coordinate values X and Y and controls the revolution of servo motors 3 and 4 by sending signals to the servo motors 3 and 4 corresponding to axial pulses DELTAX and DELTAY obtained as the result. In the case of circular arc interpolation, the pulse distributing means 61 sends the axial pulses DELTAX and DELTAY to a tangential direction calculating means 62. Based on those axial pulses DELTAX and DELTAY, the tangential direction calculating means 62 calculates an angle (tangential angle) theta formed by an advancing direction 111 of a tool 62 and a tangential direction 112 and outputs the tangential angle theta to a spindle motor 2. Since the spindle motor 2 is revolved just at the tangential angle theta, a blade face 220 of the tool 22 is controlled so as to be always directed toward the tangential direction 112 corresponding to the advancing direction 111.
