tooljockey works for Fraisa. He also has about 10
yrs of using mastercam building molds and more than
20 years of machineing. Steve use to work this area
but Brian took over a few years ago.
Hey Brian I got your phone message, I guess you must really miss Steve.
silhouette boundary > activate solid selection > (deselect) solid body so that only solid face is active. Works for me.
What I have found to work when a toolpath hangs is to open internet explorer and bounce around opening different web pages. That will almost always get the toolpath processing again.
You want to take about an 1.8" step over any less and insert life goes down. If it chips an insert you will hear it. Inserts are cheap rotate them at start of a long cut. You can't tell if they are dull buy looking at them. Like TR said use the book settings for best results. If you are using coolant make sure you flood it well and have a good vacuum system to remove the steam. Air blast works best.
I've been using them since they came out in beta and have not had any gouges.
Switched from using sandvik cutters to Mitsubishi 2" AJX for Core roughing and 3/4" AJX for Rest roughing. I have seen cutting times for roughing out P-20 cavity and core blocks drop from 5 hours per block down to 30 min. per block.
The high speed finishing paths do a great job on hardened steel.
Processing times are not that much different.
I still use a mix of new and old cutter pathes when cutting electrodes.
The loop is caused by the way Hurco has there home position set to a different corner then everyone else. Not sure but I think this is what we had to change to get it to work.
Set the swg18 variable to 1 for Boss's left handed coordinate system
# on G18 plane - G17 and G19 have a right handed coodinate system. This will
# cause G2 to be outout as G3 and G3 to be output as G2 only when G18 encountered.
I've been running Hurcos for 20 years.

Programing options > DXF & 3D
Conversational programing is very easy to learn
less than a day for most.
Any shape you can program for a 3axis mill with mastercam you can cut it in a hurco without buying the 3D option. The 3D option is only for conversational programing. You can rotate about Z or X or translate a contour in Y. You can't program a constant radius that does not lie in the X,Y, or Z plane. That is what mastercam is for.
We do all our holes using conversational. Very fast you have alot of control to change anything
in just seconds. Peck,depth,retract,location,add holes,add tools and alot more.
Plus the best thing is you can see anything you program on the graphics screen in any of the 4 standard views.
Hurcos are capable of taking some hard crashes
with no more damage than a little pride. The Makino could not handle a small crash without at least tipping the spindle or table.
Are hurcos the best built machine out there. NO but you can be cutting parts without much training or an offline programing system the day the machine is first powered up.
You can switch between NC and conversational
and not loose your part or tool setup.
You can turn the machine off and back on and not loose anything.
If your still kunfuzed goodluck in the laundry business.
beej,
80% width and climb using the new highspeed roughing toolpaths works great with the AJX. We bought a 2" dia. cutter and in P-20 I cut using .051 DOC > 150 IPM > 745 RPM > .051 Chipload > 6" overhang from the Spindle. It cut for an hour and I did not have to rotate the inserts. It is a much better cutter then any sandvik cutter we have.
