METHOD, SYSTEM, COMPUTER PROGRAMME AND A COMPUTER PROGRAMME PRODUCT FOR TOOL WEAR COMPENSATION

摘要

The present invention relates to a method for compensation of tool wear in orbital drilling comprising the following steps: providing a receipt (Fig. 1) for the orbital drilling in a predetermined material (4; 14),wherein one parameter is the tool offset to achieve a desired hole (13) diameter; collecting parameters (6) of the tool (12); and calculating a first tool wear value (8). The method further comprises calculating said first tool wear value(8), based also on the material parameters (4; 14), in addition to the receipt (Fig. 1) and the collected parameters(6); receiving an offset compensation value (10); and drilling of the hole diameter in the material,by compensation for the offset compensation value (10), such that the diameter of the hole is dynamically adjusted during the orbital drilling operation in order to obtain the desired diameter of the hole (13). The present invention also relates to a system for orbital drilling comprising a computer (18) including a computer program (P) for carrying out the method. The present invention also relates to a computer programme (P) and a computer programme product for performing the method steps.
