Here is an example of 2 simultaneous tapping operations on stations 4 and 5, with compensation head.
 1. Create an operating line to program the tapping speed (spindle S3). This operating line is found between the line of station 4 and 5. Insert operations 10:1 to 10:3.  2. Insert start of operation 9:5 synchronisation with start of operation 10:2, and an end of operation 9:5 constraint with the start of operation 10:3 3. Insert a start of operation 12:5 synchronisation with start of operation 10:2, and an end of operation 12:5 constraint with start of operation 10:3 Tip:  4. Insert an end of operation 9:4 synchronisation ( tapping, station 4) with the start of operation 10:2 (reversal S3), end of operation 12:4 (tapping, station 5) with start of operation 10:2. With this particular synchronisation, the shortest operation starts working a little later, in such a way that the two operations ( 9:4 and 12:4 ) finish at the same time, before reversing the S3 motor. Operations 9:5 and 12:5 execute untapping. In the opposite case (without this synchronisation), the quicker tapping operation will wait for the other, which would lead to tap breakage or non compliance with the depth. 5. Programming operations according to the part drawing and the required tapping speed. Comments: The required tapping speed will be the same for stations 4 and 5. Therefore, define a mean tapping speed between taps M12 and M8. THINK PARTS THINK TORNOS ascl.com |
