I was wrong about the other 2 varibles. These are only availble in the 2 line G76 cycle
I belive if you are going to chase the thread with 2 canned cycles and you plan on changing the K value you will need to figure out the difference in the K varible over the angle specified and adjust z value accordingly to what you find
If I were to do this with a canned cycle and I needed to take out deflection.
use a G76 with a angle of zero take a smaller cut to insure tip dosent break. Then follow up with a G32 thread cycle at the same Z and use this to chase the deflection out you can repete the G32 as many times as needed.
Another option is to use the I varible to compensate for deflection if the defection is the same from part to part
I havent done this in a while and might me missing some little things so you may want to sample the above on test parts to work out the bugs. |
