    At the machine, the operator sets each face that gets worked one as a seperate workoffset (X Y Z and B) only on parts that I can center on the pallet do I use the index positions (B0 B90 B180 B270)

     

    Thanks dave i will find pfcout in the post and change it to "B0"

     

    Jay

  2. Using the MPMaster post is it possible to force B0 at every index, in place of say B90. B180. B270

    Example

  3. I remember a flex writer during my apprenticeship. Lots of pencilcam. First real cadcam was some crazy thing Cadkey put out around 1995/1996. Then Mastercam V6, upgraded to V8. Someone then had the bright idea to abandon Mastercam in favor of Camworks by Tek-soft. Changed jobs used Mastercam V7. Changed jobs once again, began using Tek-soft Pro-cam. Got fed up with the lack of support tek-soft.Got back to Mastercam V8 Level 1, Upgraded to 9.1 Level 3 with Solids. Just been offerd a job were they use Surfcam. Have an Interview tomorrow with a Company that has Mastercam ( Fingers crossed),

     

    Overall, to pay the bills I will Learn Surfcam. If you know Solidworks, then Camworks is okay but its still a Tek-soft product that I find clumsy at best. People I talk to that don’t have Mastercam say, If They had the $$$ they would get Mastercam.

  4. Hey guys the local cable company finally got its $%^& together.

    I have put the casting body my former employer wanted to draw in 2d and machine in 2d on the ftp site MC9 folder phototube.

     

    Not a really difficult part, Clamp to 4th axis or haas indexer Produce all inside features in one set-up

  5. Thanks jmparis. You are right. Give them what they want. I started out giving them the quick 2D flat programs, then along came the more complicated parts and I discovered how to draw in 3D and just picked depths. Somewhere along the line, all programming should only take 10 minutes per President of the company. "I worked for a job shop that manufactures medical devices."

     

    Your right CMR. They are in the dark ages. I still can't believe in this day and age that people still want to do that. "The 2D way." I will try to put the part on the FTP site for you to see.

     

    jmparis, do I know you? Have you ever worked for Instrumentation Industries in Lawrence, MA?

  6. offtopic.gif First let me Say this is only my third post. In the past I have used the search function to answer most of my questions. You all have been a great help.

     

    Guess you could call this an off the record question 2d versus 3d

     

     

    Given any two dimensional print is it better to program from the flat geometry and type in the depths or create the part in 3 dimensional wire frames or even in solids.

     

    I prefer the 3d / solids way, using the customer’s flat geometry to either extrude into a solid or xform into a wireframe.

     

    We receive solid models, dxf prints and even PDF files. Management wants to create programs from the flat dxf prints. Only if the run of part are in the hundreds do they want create it in wireframe or solids

     

    If it’s 5 square blocks with holes or 500 plates with 30 different machinable features you still need to create code for it, correct. And why not in 3D

     

    The company I work for only has an old copy of tek-soft 2d . I was hired because I’m register Mastercam mill level 1 user and they were interserted in seeing just what Mastercam could do. (I since upgraded to mill level 3 mr304)

     

    Yesterday I was given the boot for creating a casting body in solids. When I should have done it in flat 2D so they say.

     

    I will try to post the part to the ftp site for all to see. (mc9_files/sony x710 phototube a)

     

    In closing how would all you gals and guys handle this 2d versus 3d issue.

  7. I have found that programming to the center of rotation is the best bet for most pieces. It does cost you more up front time in planning and documentation. Unlike Verticals the key to Horizontals lays in the Tooling, Fixturing, and Programming The type of work will dictate how you chose to do it. I have also found that it is best to give each face, or rotation a new work plane. Fixtures are never where you think they should be on the pallet. There are many ways to skin the cat, this has worked well for myself. smile.gif
