  1. For the last couple of years I haven't really been doing any programming, but have been helping a few people out locally here and there. I stopped recommending MC as a new purchase at around X4, but still thought to myself that if I ever needed another seat that I would probably still stick with MC. Now I say nothing unless asked, but when I am I tell people to stay well clear. I even recommended to one bloke that if he REALLY wanted MC that he should buy a seat, install Xmr2 and forget maintenance. Xmr2 would do more than he would ever need it for and then some. AND it was a reasonably stable release. I think he bought ONECnc. I know there are probably loopholes in the EULA, but someone one day is going to sue CNC for a providing a defective product. They can crow all they like about all software being buggy, but the lack of regular updates/patches together with non-maintenance customers being "frozen" into broken releases is going to tip someone with deep pockets and a bad temper over the edge one day.

  2. Rekd, Like Matt said, down cut, or even straight edge tools will reduce the burr. I actually spent the first 10 years of my trade machining only plastics. When they still made woodworking routers from HSS a good clean chamfer could be had by doing a light conventional cut with a straight flute HSS tool. HTH Bruce
  3. What about a core drill? a 3 flute self centring drill might have enough web in contact to drill straight on the second hole without needing to plug the first??? Bruce
  4. Dave, On my little fanuc c-axis lathe I used to adjust the entry of a timed thread by changing the Z start point on the threading cycle. e.g. if I had a 1mm pitch thread that I needed to "rotate" 180 deg, I would add 0.5mm to the Z start point. The only catch with this method is that it was trial and error for the first couple of parts. Not a problem on little stuff, but maybe you could use an acetal setter to get it right before risking the real job? HTH Bruce
  5. This same request has been brought up at least once a year since I have been a member here. About time it had some attention I think. Bruce
  6. I might be in the minority, but I've always used absolute. Having said that all but a few of the 5-axis machines I have programmed for used either TCP or dynamic work offsets. For the ones that didn't I measured where the 4/5 axis intersection was and then used that as my nominal origin in MC. Outputting a different work coordinate for each view then allowed me to tweak where necessary, but if a part was no tighter than 0.1mm tolerance it was usually good enough. What machine may I ask? Bruce
  7. Putting the parts in the freezer for an hour beforehand will help. Depending on how many parts you need, it might be easier to make a mould and have someone pour them. Bruce
  8. Ahoy! I have a drawing that was done in France. There is a keyway that has its width dimensioned as "20slc". Does anyone have an idea what this is? Thanks Bruce
  9. Mic, I just use the same tools that I would for ally. That is in 96% pure castings. HTH Bruce
  10. I have a Tormach mill in my garage and make small turned parts with it regularly. I have a gang block, but sometimes it is easier to put a few turning tools in a vice separated with some parallels. Bruce
  11. Resurecting an old thread here. Has anyone here done this on a Mazak control? We have a Y-axis quickturn and an Integrex E-420 that we would like to try it out on. Thanks Bruce
  12. I'm with Joe, a router of some sort would be the best bet. Bruce
  13. In those materials I wouldn't hesitate to recommend multi-tooth threadmills. Bruce
  14. Ahoy! Please say hello to Simon. He's having an MCX5 demo tomorrow and I would like to show him the level of support available on this forum. :oldforumcheers: Bruce
  15. No sub spindles or multiple turrets here Joe. Just BIG jobs in small batches, but I get your meaning. Bruce
  16. Ahoy! The company I am at is looking to upgrade the limited offline options they have now to a full seat or two of CAM software. I no longer programme and have been out of the saddle for a while, but have arranged a 30 day trial. I'll be doing the demo to the company myself as the VAR here is 1000 miles away and he trusts me to handle it on my own :eek: I was never really into the lathe side of things, mainly milling up to full 5 axis. Can anyone help me out with some good examples of jobs for the following machines: Integrex E410 Any Y-axis lathe Any VTL with or without C-axis milling. Also need to highlight the machsim capability so am hoping the install CD has a range of similar machines. Any and all help appreciated. Bruce
  17. For me it was always a coin flip between Mitsubishi and Iscar, but now that the new Iscar range is double sided the choice is easy despite the price. Bruce
