can you describe the transition from full z depth to no wheel contact? |
If your asking about when the flute is finished, & the wheel exits the flute, I program a small amount of
over travel (approx. 1.0mm) I would still be in G91, I also do the same before the wheel touches the drill (
pre travel, approx. 1.0mm (G91)), so that the wheel isn't slamming into the drill, when it rapids up to the drill (G90).
What is the relataion/ratio? (2ipm along x-axis to 1imp along the y-axis) |
I might have mislead you, when I said "I use all 5 axis to grind the flute", actually for a basic 2-flute drill the "Y,Z, & C-axis" are only used to Rapid (G90) up to the drill & then stay fixed in that position, the actual infeed (G91) is in only "X & A-axis"
I work in metric so the 2ipm converts to "50.80" that sounds correct for the "X & A-axis" feeds (G91).
Is there any y-axis movement during the operation? |
No, after the "Y-axis" Rapids to the drill it stays fixed in that position, during the entire grinding process.
Does the c-axis change during one part. |
No, just like the "Y, Z-axis" the "C-axis" Rapids to the drill and stays fixed in that position, during the entire grinding process.
NOTE:
Just like any other program everything depends on how the machine is setup, how many axis, etc...
