OPTIMAL POSITIONING METHODS OF INTEGRAL DEFORMATION SENSORS – EXPERT KNOWLEDGE VERSUS MATHEMATICAL OPTIMIZATION

Up to 75 % of the overall work piece error can be caused by thermo-elastic behavior machine tool. Therefore, correction methods based on machine-integrated sensors were intensively researched during last years, in order determine Tool Center Point (TCP) parallel process. One these includes integral deformation sensor (IDS), which detects along length a structural component machine. The TCP is modelled measured deformations, mechanical model parts and kinematic Currently, setup for specific machines usually defined an expert with help his or her domain knowledge. There are existing mathematical optimal positioning. aim this evaluation positioning versus methods. parameters varied lengths positions IDS. Criteria achievable accuracy prediction sensitivity small variations position, as they might occur installation.
