4 Programming 4.2 Tools 4-10 Tool change position A tool change position must lie next to or above the workpiece to prevent tool collision. With the miscellaneous functions M91 and M92 (see page 5- 39) you can enter machine-referenced rather than workpiecereferenced coordinates for the tool change position. If T0 is programmed before the first tool call, the TNC moves the spindle to an uncompensated position. If a positive length compensation value was in effect before T0, the clearance to the workpiece is reduced. TNC 360
4 Programming 4.3 Tool Compensation Values TNC 360 For each tool, the TNC adjusts the spindle path in the tool axis by the compensation value for the tool length. In the working plane it compensates the tool radius. Effect of tool compensation values Tool length Length compensation becomes effective automatically as soon as a tool is called and the tool axis moves. To cancel length compensation, call a tool with the length L = 0. Tool radius Radius compensation becomes effective as soon as a tool is called and is moved in the working plane with G41 or G42. To cancel radius compensation, program a positioning block with G40. Tool radius compensation Tool traverse can be programmed: • Without radius compensation: G40 • With radius compensation: G41or G42 • As single-axis movements with G43 or G44 Fig. 4.4: The TNC must compensate the length and radius of the tool R Fig. 4.5: Programmed contour (–––, +) and the path of the tool center (- - -) R 4-11
