    Tiny Slots

    We do a ton of smaller stuff here. Ramp usually works the best. A few jobs I do are with a 1/16 or 1/32 endmills at 10x diam. no problem.
  2. Has anyone ever used these? We do a lot of smaller parts with places that are difficult to get in with a standard chamfer tool. A lot of hand deburring. Trying to get a tumbler but not a high priority for my boss because hey he is not the one sitting here doing this PITA hand work. I was wondering how theses work and if anyone has experience with them?

    Deburring Endmill

    Don't have multi axis. Maybe that's why I could not find it. Not looking there.

    Deburring Endmill

    That I have not tried, the ballnose for deburring. I do use the chamfer tool path all the time. When the tool is set up correctly you can control the chamfer nicely. Most of the times we just want to break the edge so there is no burr. Maybe .002-.003 edge break. Edit: When you talk about "deburr toolpath" are you talking about chamfer?

    Deburring Endmill

    I guess my real question is how do they function? I mean they just look like a roughing end mill that would give you a crappy finish.

    Haas 617 alarm missing adress code

    +1 Usually because of the read ahead the alarm is on a line in front of where it alarms out.

    Haas 617 alarm missing adress code

    Copy and pasted into editor put it on floppy and loaded into 25 year old VF0. Ran fine. Could be just a glitch once in a while I guess.

    Better way to remove this material

    Welcome back.

    Machine definition, control definition, operation defaults. Selecl all, edit common parameters, coolant off. Just winging it off the top of my head but I think I got it right.
  10. Sounds like a settings issue. I run a 3 Haas machines. A 1994 VF0, 2005 VF2 and A 2019 VF2. Use wear all the time and not an issue if your settings are correct. For circle mill be sure you have it set for perpendicular and 90 degree. Edit: If you want to contour an ID use the formula of ( dia. of hole - dia. of tool/2 * .4142 ) with a sweep of 135 and you will drop into the center of the hole and sweep on and off with no problems. Example 1/2 inch hole with 1/4 inch endmill. .500-.250 = .250/2 = .125*.4142 = .051775 Lead in and out line and arc .051775 with 135 degrees of sweep. Works great for slots also.

    G98 will retract to your initial Z number whatever it is on your G43 line. A G99 retracts only to what your R value is.

    Top of stock

    Set your retract to incremental of something like .1 and clearance to .100 absolute. Be sure you uncheck use clearance only at start and and of cycle. This will rapid your drill to -.400 drill your hole and then retract to .100 over your zero before moving to next hole. ( 3/16 SPOTDRILL ) ( SPOT HOLES ) T1 M6 G0 G54 G90 X0. Y0.

  13. They are also really good on copper and brass. As a microwave component company everything we do is aluminum, copper and brass. I use the Shearhog on all 3 with great results.

    Question about posting

    Save and save often. Nothing is more frustrating that having an hour or two into programming a part and having Mastercam crash or something else happen and you lose all the work you have done.

    Chip Trap

    So a few weeks in use and I would give it a big . The amount of tiny chips floating in the coolant has dropped almost to nothing. Can slide it out from under the drainage chute easily without moving the coolant tank. Cheap enough that it is well worth the cost. Still running the first 2 filters so the life on them is pretty good and they are not expensive to begin with.
  17. Guy here at work found this. Trying it out now in our older VF2. We use tons of small endmills and the small chips are always getting through the baffle system that Haas has for their coolant tray. Will try and remember to post back on results. 2 days so far and seems to be working well.
  18. Still using Shearhogs here also. Years ago at one place we were doing larger plates with a flatness callout of something like .008. Had problems and usually used the whole tolerance with the cutters they were using. Got them to buy a Shearhog to try. Without changing anything we went to flatness of .002-.003.
  19. Our new VF2 has the Renishaw tool and spindle probes. We do many jobs that come from the center opening of extruded wave guide stock. One job we have to do we mill all 4 sides holding a dimension to the center. I was wondering if anyone has used a right angle tip inside of a machine for picking up in Z axis in the center of an opening. Somethig like this..... To probe .... and set Z for each piece.

    Right Angle Probing

    Hmmm. I will have to email Haas and ask about that. I was told directly by Haas it could not be done with the probe because it will not trigger. The new NGC sucks IMO. I can do stuff faster and better on my 2005 control. Used to be able to paste straight to a program from the old VQC templates if I remember correctly. Now everything needs to be written out using the inspection plus. Always thought one of the best thing about Haas was the controls. Now not so much. And the interlocks have me banging my head against the machine. Can't even turn on a chip conveyor to clean the machine with the doors open.

    Right Angle Probing

    The probe we have will not probe in a Z+ direction so that ends that part of the discussion.
  22. I'm curious. Were you trying to get your post to put out a G57?

    Right Angle Probing

    I will be researching that end of it soon. This is a job that will be coming down the road so I have a little time. Will update when I get it figured out if I get it figured out.

    Right Angle Probing

    Oh well I'm screwed.

    ARRRGHHH!!! Customers

    Sounds like my place. But here we do it to ourselves. Print different from the model is standard MO. Getting better as we internalize more and more machining. I go in and make him fix it. Best is when we get stuff he has made outside on the cheap and we fix it.
