We use a place in Connecticut, Called Primary Cutter Grinding. They make endmills called SUPERMills which are great and can make custom ground tooling as well. They have pretty quick turn around when all they need to do is take an existing tool and grind an angle and a radius on it. www.supermill.com

Use the High Speed rest rough toolpath Select your STL file as the CAD file and set the "Rest Material" setting to CAD file That is what I was trying to do with my tool path, but when I backplot and run the code, it cuts where there is no material (AIR). Any ideas? Maybe a setting??

How can you get rid of the wasted air moves? I used an High Speed Rest Mill toolpath and instead of defining a roughing tool I used the STL file, however it still cuts alot of air. Is there a way for Mastercam to just cut where stock is left, kinda like when you rough with one tool path and then Restmill, and it only cuts whats left. Is there a way. Maybe I wasn't using the STL correctly either. Is there an Online resource for the use of STL? Oh by the way, By using the STL file and High speed tool paths I was able to speed up the roughing cycle, I was just looking to cut as much time out as possible. Any advice would be much appreciated. Thanks

Hurco's run very similar to that. Needing all positive values for drill cycles. We used the MPmaster Post and then just modified the pdrill$ area of the post. I'll have to get to work, so I can copy and pass it up here. But its not really too hard to modify.

i've been using Supermill for Aluminum. They last forever.

Machinist Calc Pro would be nice, if there wasn't so many key strokes to remember. Waste of money IMHO

chances are it is a cutter comp issue. I would try posted the code, with computer set as the comp. See if it works. If it does then it totally has to do with how Hurco is using cutter comp. I've had problems with our hurco and cutter comp before. Sometime wear works, and sometime control works. All depends on the part...Hurcos are really tempermental

I open .PRT files in Solidworks then save off as .SLDPRT

I think this is a great idea and would be a huge help for everyone. I am always wondering if I am really pushing the limits of my tooling and machine or not. The boss never wants to hear a thrown part or see a broken end mill but is always interested in getting more productivity...

You should be able to modify your post so that it doesn't output a G80 until after all your holes are done. That is what's causing your machine to go back to z home.

If anyone has found a why to modify your post so that clearance planes do work...I would greatly appriciate the info...What I would want...If you have ever run the hurco conversational programs is. Position above the hole, lets say at 1" then rapid down to lets say .02" then start the drilling cycle, once done drilling that hole, rapid back up to 1" and move to the next location, rapid back down to .02" and start all over again.

I will have to look at my post when I get back to work. I had to change our post so it worked with out hurcos...that is all we run. If I remember correctly, you need to reformat the drill depth to be a positive value, in your format statements, and you need to add the z start to your z depth to get the correct z output. Its always confusing when I talk with other guys and they see that a drill cycle has all positive z values. The one thing I found that sucks, is you can't use the clearance plane check box...screws everything up. If u backplot in mastercam it works, but when the hurco runs it....no such luck.
