摘要： PURPOSE:To facilitate removal of an electrode indexing rotary device from a main head and to enable storage of the electrode indexing rotary device, by a method wherein a holding member, capable of being removably held by horizontally moving the electrode indexing rotary device, is disposed in the desired position of a column separated from a main shaft head. CONSTITUTION:A dovetail groove 16 formed in a mounting part 8a of the lower part of a main shaft head 8 is coincided with a dovetail groove 20a formed in a holding member 20. A bolt 19 of a stopper 18 secured on the back 8c side of the mounting part 8a is unscrewed, and the stopper 18 is moved upward through utilization of an oval bolt hole 18a formed in the stopper 18. By unscrewing a crank bolt 14, an electrode indexing rotary device 1 is horizontally moved backwardly, i.e. in the direction of a chin part 9a of a column 9. The rotary device 1, moved in a state to be engaged with the dovetail groove 20a of the holding member 20, is moved until it makes contact with a stopper 22. The above operation completes removal of the rotary device 1 from a main shaft head 8. Thus, removal of a cable hose and the like is eliminated.

摘要： PURPOSE:To permit the feed control with high accuracy and small hysteresis value by stepwise correcting the hysteresis width generated in NC feed-direction change of a table through backlash correction. CONSTITUTION:The figure shows the loci of the feed instruction values and the actual shift values of an NC feed shaft, and the full line 40 shows the advance pass in one direction, and the point A is a turning point, and the alternating dotted line 41 shows the locus in the case where backlash correction is not executed, and the dotted line 42 shows the locus in the case where backlash correction is executed. In backlash correction, the part A-A''' in which a hysteresis width DELTA is generated is equally divided into three parts, and the backlash amount is equally divided into three parts, considering the hysteresis width as backlash amount. The backlash amount for DELTA/3 is corrected at the turning point A, and the backlash amount for DELTA/3 is corrected between A-A'''/3, namely at the point A' and then backlash correction is performed for DELTA/3 at the point A'' successively, and the total backlash correction amount is made equal to the hysteresis width DELTA at the position A'''. Therefore, the error in the advance and return loci can be reduced.
