| AdeV:
Now I'm finally starting to get the hang of CAM.... and having taught CamBam to speak TNC151 conversational :ddb: (no g-code for me :scratch:), I've been starting to actually make things with the ole Bridgeport Interact. First "completed" item, a gearbox bellhousing adapter, converts a Lexus auto box bellhousing to a Toyota Supra gearbox: Yep, I made it in machinable wax :) It remains to be seen if this version is strong enough to take the anticipated 320bhp of a V8 in full cry :lol: I may make another one out of aluminium... Anyway, having done that, project 2 beckoned - exhaust manifolds. Designed & drawn in CamBam, this is the holes being drilled out: And in freeze-frame, because it amused me: Of course, those lovely swarf tails threw starting-to-get-a-bit-smelly coolant everywhere... Ho hum. Tomorrow, I will mill the shapes out.... hopefully not sacrificing too many cutters along the way :thumbup: |

Very nice part AdeV. Did you make your own wax from the recipe listed here in another thread, or is that the real stuff? |
| Brass_Machine:
Ade makes his own... but it definitely is the real stuff. I have some around here that he sent me. It is professional grade. Smells nice too :lol: Ade... part looks good. Did you have a chance to check to see if it fits? Eric |

If you were speaking the same language as everyone else then you could have used G73 - high speed peck drill where it drills, retracts about 1/2 a mill to break the chips then drills again. Different animal to G83 which retracts fully to clear the chips. |

The gearbox side I can definitely do today, just need to separate the manual box from its old bellhousing. --- Quote from: John Stevenson on March 16, 2013, 06:16:40 AM ---If you were speaking the same language as everyone else then you could have used G73 - high speed peck drill where it drills, retracts about 1/2 a mill to break the chips then drills again.

I guess the meaning of G73 changed somewhere along the lines, or Heidenhain used it when they shouldn't have done? The only drilling options are G83 (pecking) or G84 (tapping). I suppose it would be possible to write my own pecking cycle & call it via G39... but I can also do that via HH Conversational I believe. Food for thought, thanks John. Of course, what I probably ought to do would be to scrap this '80s controller and get all modern.... but, while it still works, I'll stick with it I think. Besides, the wiring diagram scares the crap out of me. |
