Posted to Practically Worthless Machinist by "Seymour Dumore" who
purchased OneCNC crapware only to have to go right out and purchase
FeatureCAM to get the job done. He's not the only one who got screwed
when he purchased OneCNC crapware. "Edster" did as well and also had
to purchase FeatureCAM to get the job done.
"Since I'm a generation behind with my XR2, here are a couple of
questions regarding XR3:
1: Since it is the roughing pass, can you use cutter comp, as in
machine cutter comp?
2: Can you tell the tool to never lift off the part until each Z-level
is finished?
3: Can you tell the tool to plunge in Z at only X3. Y-5. and nowhere
else?
4: Can you tell the tool to finish each location to full depth before
moving onto the next location?
5: Since it has filleted bottom corners, can you use a sharp roughing
tool using .01 side and .005 bottom allowance without violating the
fillet? I mean that by using 2.5D toolpath instead of a SMT?
6: Can you use a 1" rougher instead of the 1/2" without modifying the
model's inside radii that may be less than R.5" ?
7: Can you analize the finished toolpath and change feedrates
automatically where possible to maintain the 60% spindle load? Say at
engagements of only 10%? Perhaps even increase to 500%? Can you slow
down in inside corners that are only 110-120% of actual tool dia?
8: Can you change the toolpath start point to any SPECIFIC location
you SPECIFY EXPLICITLY? Say the upper right corner maybe? Note that is
not equivalent to plunge location!
9: Can you turn this into a program of 9 parts using 9 workoffsets but
still have only one place to modify the operation?
10: Can you flip this part and then use the leftover material from the
1st op as stock for the back side machining? That is Original stock -
1st operation = Stock to machine in 2nd operation.
11: What do you need to do to add a clamphole in the middle of the
part and then avoid the bolt that goes through it? I can also say add
a clamp at any other arbitary location and then avoid that one.
12: Assuming the wall is tapered, can you use a tapered tool knowing
only it's actual taper angle to properly cut and simulate the part? Do
so at multiple rough and finish depths!!!
Please note: No 3D toolpaths are allowed as it would likely
prohibitively increases cycletime and the lack of tool comp makes the
program un-adjustable for size without re-posting.
Since Featurecam does this (and more) out of the box, these are honest
questions to determine if I should have waited 15 months for the
release of XR3."
