    Looking for MasterCAM Skill testing.

    Can you attach the pdf file for this quiz? my company is in dire need of a better filtering process for applicants.
  2. Good afternoon, I'm wondering if it would be possible to alter my 5 axis post to output "C" for the table on the trunion instead of "B"? I've been manually editing my posts to fix this issue but like most of my problems here I'm sure I'm just a few clicks away from saving myself all sorts of time.

    MC 2020 "dependencies"

    I just updated to MC 2020 and so far am enjoying the subtle changes (unpopular opinion I know ). I noticed a new tab labeled "dependencies" in the toolpaths manager. Can anyone explain to me the function of this key and how it can be used to better my programming / experience?
  4. May the powers that be please enlighten me as to how one would go about using a double sided 45 degree chamfer mill to deburr front and backside profiles. I have achieved this by modifying a key cutter to represent the tool geometry (.125 wd cutting edge with 45deg angles front and back) but by doing so I cannot use the "2d chamfer mill" parameter. So I'll adjust my numbers and lie to the program to get the tool to work... Not the most preferred method but it gets it done.. I cant help but feel there is a better way to go about this. I'd love to be able to just select my solid edges and use the chamfer mill parameter and have the control recognize the tool. Unfortunately I can't include a file for this particular part but just imagine you want to edge break the front and backside of a gear using an axial live tool in a C+Y axis lathe.

    setting default tool library

    okay great! thanks guys.

    setting default tool library

    I've been working on creating a tool library for what I have available at my shop. the only problem is MC reverts to its original "lathe inch" library every time I open it. I'm wondering how I would go about setting my custom library as default so it will be active upon startup?

    It's a C and Y axis lathe. This was an experiment in trying new toolpaths. I did notice that when I turned the comp off and it went off the center line of the tool the angles lined up. I'm wondering if I could lie to the dimensions in my geometry and add half the diameter of my tool to make it work.... or I should probably just learn how to do it the right way .. anywho, thank you for the input.

    Better yet, how would some of you approach doing this part?
  9. So I'm attempting to program a c-axis contour but it appears my tool is not lining up properly causing my angles to be off. I chained my geometry using linked edges from the inside diameter of the tabs. I set my rotary diameter at the diameter of the geometry that I chained (not sure if this is the cause of the problem) it seems to be leaving more material towards the tops of the tabs as if the centerline of the tool is off. I have tried switching between "wear" and "computer" for my tool comp settings and that doesn't seem to make a difference. I unfortunately cannot post the file for inspection but I'll try to upload some pics that might help in the diagnosis. Any suggestions would be much appreciated as I don't have anyone at my shop to reference for info. The red line was created to help show the tool being off. thanks.

    Shortcut for reverse chain

    Thanks guys, this is already making my life easier.

    Shortcut for reverse chain

    Time and time again I find myself getting sandbagged by the chaining direction while creating tool paths. Is there any sort of hot key for reversing the chain direction without having to physically click the double sided arrow in the dialogue box ( I know, how terribly lazy of me) .
  12. So it seems my options for mastercam education outside of forums and youtube are A. three day courses for specific subject matter i.e lathe, 2d mill ,3d mill etc. B. professional certification through mastercamU or C. purchasing tutorial books and working through them. In your opinions what did you find to be the most helpful approach for a new guy wanting to rapidly advance his skills?
