We have just recently taken ownership of a brand new VF4. Fantastic machine, but a few questions on basics. We have watched most of Mark and his tips of the day, but some things don't make sense to us. I know I could call haas and get these questions answered, but I figured I would try the collective on here and hopefully teach someone else a thing or two.
1 - We purchased the option for a second home position. Is there a G or M code to utilize it at the end of the program? I could have the operator push the button on the HMI, but we would like to incorporate it into the program.
2 - canned cycles and VPS - The VPS works great for us and can eliminate the constant need to use Mastercam to do simple hole patterns in our sheet metal parts. The issue we have is two fold. First, when the program starts, it goes directly to center then moves out to the first hole location, this issue dovetails into the second fold with this question. Clearance plane and feed plane. Maybe it is our mis-understanding of the "fill in the blank" parameters, but I cannot seem to find this out.Example below:
Simple 6 hole pattern at 3 Inch diameter equal spaced. Spot drill first, the finish with a .050 Inch drill. Fixture holding with soft clamps holding the part to a chuck under it. some of the chucks have a "protruding center" in addition to the clamps.
The wasted time that comes about with rapiding down to the clearance height then feeding at cutting feedrate until it finishes it drill then rapid back up to clearance height.
In Mastercam, there are settings for clearance height and feed height. I set the clearance height to say 1 inch and the feed height to .010 Inch. It rapids down to .010 above the first hole (not center like the VF4 VPS is doing), drills, then rapids to the clearance height, moves to the next hole, rapids down to .010 Inch and drills. Rinse, lather repeat until finished.
In The HAAS VF4 VPS, it would rapid down the the clearance, feed at the feedrate specified (say 10) through the whole inch, drill the hole, rapid back up to clearance and move to the second hole, then feed down at the feedrate.....wasted time!
The canned cycle snippet generated gives me the following:
S4000 M03
G43 H02 Z0.5
M08
G82 G98 Z-0.01 F6. R0.5 P0. L0
G70 I 2.06 J45. L8
G80 Z0.5 M09
G00 G90 G53 Z0 M05
Where does the z value in G43 H02 Z0.5 come from. It seems to populate from the R value we input. Do we have to manually change this z value each time we program?
Is there a way in the canned cycle to specify parameters for A) moving to the hole before rapid down to the feed plane to avoid hitting the center plug B) changing that z value.
