For the value of the D-Number please have a look at the documation how it work. Important is also if you have a inclined axis your Reset-Mode for the tranformation should be activ so the the transformation ist activ after reset, because yout have differnt coordinationsystem between transformation and without transformation. Please check MD 20140 = 1 24100 = 1024 24110[0] = 1 24110[1] = 2 24120 [0] = 1 24120 [2] = 2 24700 = your angle of your inclined axis if it is fixed When you register the dresser or workpiece you can have a look in the extend-data of thetool an there you see the calculated value for D1 to D6 for the wheel and D7..D9 for the dressers.

For the the dressingposition is it important is it only the wheel on 30 deg. or is also the X-axis on 30.deg . When the x-axis is on 30deg. you need also a actic TRAANG -Transformation during setup the machine because the calculation of the dressing position is based on machineaxisvalues and the machineaxis is 30 deg. That means when you move the x-axis the z-axis makes also a movement. For this you have to change the MD's like the first mail, the calculation is in cycle401 ... For more information please send me a NC-Archiv.... For the questions. 1. you can dress this wheel with Version 01.04.03... 2. yes it is possible 3. if you have this wheel without shoulder you doesn't need a X-Overflow 4. The Shoulderheigth and ... are calculated in CYCYLE439 5. You have to teach the dresser on the left corner 6. G41/G42 is aktiv during dressing 7. You can use dresser 1 or dresser 3, but dresser 3 you cannot select the direction 8. register the dresser is enough 9. deleting dressing amount is only nessesary when you change the wheel 10. D1 for the wheel is correct
