  1. Being a long time Mastercam programmer, I had to switch to Partmaker to program Citizen multi-axis, multi-spindle swiss machines. Partmaker is no Mastercam, but it is very effective for programming swiss machines. There is a lot going on in a swiss machine. Partmakers graphic module has saved me many times! The geometry creation side of Partmaker is outdated, but it gets the job done.
  2. First regen = 55 sec Second regen = 22 sec Dell Workstation PWS450 Xeon 2.40 Ghz 1 gig ram Quadro FX500 - 128Mb
  3. 1977 Triupmh 750 Bonnieville (now in storage). Mark Monica
  4. I would think a good programmer would enjoy learning new software. I've been on MasterCAM from V3. I would accept learning surfcam has a challange. It's the same with machine controls, I always enjoy learning a new control.
  5. I'm using helix bore for the first time. I can't seem to get cutter comp to work, I'm using wear and left selections. Any suggestions. Thanks, Mark
  6. I use windows terminal (from 3.1) for upload/download and drip feed. If you make any manual edits you must be sure to have a dollar sign ($) for the end of block. If you forget and just hit enter, the program will not load. Mark
  7. We use Inventor 8 for our design work and Mastercam 9.1 for toolpaths. I've found that they work very well together. I have not used solids for toolpaths at this point, but you can take an Inventor solid and create a wireframe or a surfaced model for creating toolpaths. Mark
  8. I have a editor (PC-DNC) that has a inc/abs converter. I have not used it so I'm not sure how good it works. Feel free to e-mail me a file and I'll give it a go. Mark
  9. I don't think we'll go with a swiss type machine, all though I can't rule that out. I know it will be a 6 spindle, not 6 axis. I'm sure I could use lathe and manually edit things together but it would be nice to program, verify and run.
  10. Has anyone used Mastercam lathe to program a 6 spindle CNC screw machine? My company is in the research stage for a potential purchase of such a machine, I have no control info at this point. I know some machine builders have their own programming system (I heard Part Maker mentioned), I would like to stay with Mastercam. Any info would be appreciated. Thank you, Mark
  11. I tried it with lathe 9.1 SP2 and got the same result.
  12. Oil in frame is nothing new, my stock 1977 Triumph Bonnieville in an oil in frame.
  13. We have 3 15,000 rpm CAT 50 spindles we use for machining aluminum. We looked at heat shrink tooling and it was expensive. We use tool life management and backup tools and we like to have them the same length (within .0005 on a optical presetter). The heat shrink rep would not commit on hold this tol on his equipment. We use Command toolholders, they have a nice selection of coolant thru balanced toolholders. We have them install the pullstud and balance the assembly to G1.0(the balance could be out by G2.5 if we installed the pullstud). One note to add, we redline our spindles at 10,000 rpm, we doubled the spindle life this way. Good luck on your new equipment!
  14. We have 2 OKK HMC that have conductivity sensors on them, we use them only for spindle probing. I'm not sure how they are wired in a Toyoda, on the OKK's we use the G31 skip command. The nice thing about this style sensor, you can get very creative with probes. I'm not sure you can use it while cutting, but you can write a macro program to set variables for each c'bore. Mark
  15. We use Weiler Nylox brand of brushes in our pallet pool machining center. Each machine has a 3" and 1" brush as standard tools. I run them between 500 and 900 RPM and between 50 and 100 IPM. Weiler suggested I run the spindle CW and CCW over the same tool path. It does a great job on cast aluminum. The downside, they do wear. The brush must be engaged 1/8" to 1/4" in the "cut". You must keep on top of the wear or the brush will be ineffective.
  16. opps, I squared + J squared = R squared
  17. ScottyB, keep in mind, I squared + J squared = square root of R
  18. We have always used Trim-Sol, we machine mainly 356 and 319 aluminum cast alloys. We went through a lot of trials to extend coolant life and the one thing that made a huge difference is using ultra pure water. Bacteria will grow on minerals in the water, the harder the water, the more bacteria, more smell. We had US Filter install water pureification systems to produce dionized water for mixing with the Trim-sol. We also installed 10 micron filters on all water based coolant machines (50 micron for oil). This eliminated aluminum fines from contaminating the coolant. This also improved tool life, we found the hi-pressure and standard coolant systems were flooding the cut zone with coolant with suspended fines. Oil skimmers on all water based coolant machined is a must. Our coolant purshases are a mere fraction of what they were before these changes, It sounds expensive, but the system had a very short payback. On a side note, we also purchased a splitter to seperate the oil and water from the old coolant, this saved money on disposal cost. Good luck, Mark Monica
  19. PDG, I have all the latest patches installed. I can convert a SAT file created in Inventor 7. The native Inventor files (IPT) still dump me out of Mastercam. I wonder if I should do a clean install of Mastercam. Your thoughts, Thanks Mark
  20. I'm having trouble reading Inventor V7 .ipt files. I get a Windows dialog box telling me mill9.exe has generated errors and will be closed by Windows. I'm running V9.1 Mill with solids under Windows 2000 Professional. Also running Inventor v7.0 on the same computer (I find it somewhat easier to create solids in Inventor). Any suggestions as to what I'm doing wrong? Thanks in advance, Mark Monica
  21. I have Mori SH-630 and have had the same problem. With small arc moves the control will short cut the arc, much the same way when hi feed machining. You must use a G08P1 command before the first feed move, put it on a seperate line. Put a G08P0 after your last feed move. This is a look ahead command that will slow the feed rate automatically and cut a round hole or boss. We've gotten in the habit of using it on all milling routines for the SH-630's in the shop. The same programs run perfect on 10 year old Meldas controls, a much better control in my opinion. Good luck, Mark Monica
  22. We just finished a job with a R2.0" +.002/-.001 sphere, we used a T-MAX drill to rough has much has possible. Finished with a Valenite BHP-EC-600 boring bar with a VNFM-332 insert, worked like a charm. Note: the customer allowed a small drill point at X0.
  23. FYI, I run Solid Edge V14 with a network license and Mastercam V9.1 with a hasp on a NT machine with no problems.
  24. The file is in the MC_9 directory and is named 105346.zip
  25. I've created a stl file from a converted solid for verify, in V9.1, I get a warning that the file is not closed and water tight and an approximation will be used as stock. This approximation is terrible. I used the same stl file in V8.1.1 and it looks just like the part.I will try to put a file (the stl file) on the ftp site, I can seem to access it at the moment. Thanks Mark
