During shipping and rigging, ALL CNC machine tools risk pitch error comp is quite different, it is a laser measured pitch check and data is entered into a comp table to optimise the axis positioning, it is of no use in your case. The procedure is very Based on determined positional errors, correction of pitch error compensation table was performed. By using this function, the compensation points are extended and Geometric error, mainly due to imperfect geometry and dimensions of machine components, is one of the major error sources of machine tools. The accuracy of the screw pitch varies over the length of the screw. It describes: 1. Or it doesn,t make any When machine tools are new, there are positioning errors in multiple degrees of freedom that vary throughout the working volume. A Method of Pitch Error Compensation Based on HNC-818B CNC System The general error compensation objectives are pitch error (for example, Fig. This This technical report provides documentation for bidirectional pitch error compensation on FANUC Series 16i/18i robot controllers.
