摘要:
A method and apparatus for providing compensation for offset error in a numerical control unit, particularly a lathe, on the basis of tool nose height. Machine commands for one-block movement of a tool are modified by stored tool offset information (9) to produce corrected one-block travel parameters. Command data is generated by interpolating the parameter data for a single block and adjusting the command data for tool movement on the basis of stored nose height information (11) for the tool. The adjustment to the command data may take place continuously or may be implemented per block.
