Great thanks alot Chris and ShefferCNC. Chris, I'll be retaking your mastercam class this winter term if your still teaching it. See you then.

Thanks for the replys, but I still haven't found a solution. I still cant get the thread mill to cut it just skims around the boss. I've updated the program on the FTP /MCX_MR2_or Earler_Files/THREAD MILL HOUSING MANIFOLD.MCX These are my settings for 1"-14 Boss 25.3492(.998in) Tool 20.066 (.79) Vardex 3/8 thread mill TMC0753 Active teeth 8 Thread pitch 1.81428 Comp type computer OD thread selected Minor thread DIA set to 23.4442(.923) Right hand thread selected Top to bottom machining direction. What the heck am I missing? Thanks for any help, Kyle

Thread depth seems to be controlling how deep in Z the tool cuts, or how far down the boss it cuts. I'm Trying to figure out how to control the depth in x/y the thread mill cuts into the boss. It seems what ever i change the tool just skims the outside diameter of the boss. Thanks for the help Kyle

Jim, I just double checked every thing, changed the wear comp, and changed to absolute. There is no change. I tried changing the variables by large amounts like tool dia and minor diameter. I can see no changes with backplot. The tool still follows the outside of the boss. I don't understand what controls the tool depth. It seems like minor diameter would control how deep the tool cuts the threads. Thanks, Kyle

John and John, Thanks for taking the time to look at my program, I did what you suggested, but I am still getting the same thing. I set minor thread diameter to 23.622(.930in)

Thanks for the replys. I used that link to set it up initially. I get the same results of the tool not cutting, just skimming the part, no matter what tool I use. I first started out with a flat endmill. It was my understanding that the tool that you picked only effected the verify, and not the code that went to the machine.

Maybe my file isn't on there anymore I uploaded it ,but it isn't showing through the link on the top browsing bar. When I can log back onto the server I will try to re upload it

HI all, I posted my program on the ftp MCX_MR2_or Earlier_Files/THREAD MILL HOUSING MANIFOLD.MCX I am pretty new at this so any help would be appreciated. My new problem is. When I run the program on my test part the thread mill isn't cutting or just touches the boss. I am thread milling a 1"-14 25.3492mm(.998in) boss. I picked the circle chain on the boss. I picked a dove tail tool and set it to 20.066(.79in) diameter. I got that by measuring the tool then confirming it on the Vardex web sight. I set the active teeth to 8. Thread depth to -18. Thread pitch to 1.81428 (thanks iowajim62 for the refresher) Selected helical entry/exit for top and bottom. Selected OD thread set minor thread diameter to 1.81428(.930in) from my Machinery's Handbook. Selected right hand thread and machine top to bottom. I am using the first release of MCX. Material is AL and I am using a Vardex 3/8 thread mill TMC0753 Thanks for any Help, Kyle

Thank you very much Jimmy

Hey I remember that now. That was probably from the first month of machining school. I need to convert this to metric 1.81356 correct? Sorry for the newbie questions.

Hi I searched and didn't really find much. I know this is is really simple. I am thread milling an OD to 1"-14 the rest of the program is metric. I selected the boss which is 25.3492mm set the minor thread Diameter to 23.622(.930in). set the active teeth to 8. What I think I am having trouble with is the thread pitch. I set to .5512 (14/25.4) is this correct? I'm using the first release of MCX. Cutting AL with a Vardex 3/8 threadmill. Thanks for any help Kyle
