  1. I'm trying to figure out if it would crash or...

    I'm trying to figure out if it would crash or not. Any example I can find, is a straight shaft that is having threads put on. I'm worried about sending the threader into the spindle jaws for this...
  2. Lathe G76, how close can you get on Z to a wall?

    Trying to learn to thread on a CNC Lathe with a M70 controller, which is pretty similar to Fanuc as far as I understand. I'm trying to figure out how a G76 doesn't essentially smack into whatever is...
  3. Single point threading, you can use a single insert for multiple threads?

    Trying to learn to single point thread g-code and it looks like it's going to be a bit more difficult. The part has a 4-40 OD thread. I'm being told a 16ER 32UN and maybe it was a 16ER 12UN pitch...

    I've pretty much only furthered my tsundoku at this point. Talked to a guy that can Mastercam. I'm not sure how good he is, but it sounds like he doesn't know much about Tri, Geo, Alg. This has me...

    My shop recently switched to Tungaloy, from Iscar IC907. For the VNMG CNMG DNMG. Hopefully I have those right. I think we use either a 640 or 604 grade insert from them. I'm not sure on what...

    Lathe G-Code, U vs X, W vs Z

    I'm trying to learn to G-Code (still) for a lathe. It's a fanuc style and it's pretty much like a Haas lathe. I do not understand when, where, and why U is used over X or W over Z when calling a...

    Thank you! I didn't think about looking on ebay for used HS books.
  8. What math subjects are used when Machining/Programming?

    I'm trying to figure out what type of math is used when machining/programming. If it could be narrowed down to a specific subject, that would be good. So I can get a book and self-teach on that...
  9. Looking for Cheaper cnc machine simulator. Recommendations?

    I'm thinking about getting a cheaper CNC machine simulator. Primarily to practice Fanuc G code, for both Mills and Lathes. (Haas, Mitsubishi M70) Which I'm still pretty bad a G code. I know Haas...
  10. Lathe threading, conversation vs Goode. Difficulty?

    I’ve been trying to learn gcode and went to try and learn how to thread a npt or any thread for that matter and got bit in the rear. Thought I knew where all the info was, that I would need to...

    Generic endmill vs A36 plate?

    I'm just wondering if anyone knew what would happen. I'm wondering if a generic 1/2" 4 flute carbide endmill can work on A36 steel without breaking/wearing out. (Don't know if there is a coating)...

    Sadly my shop has only slightly better coolant quality... In some of the machines anyways. Some of the machines have skimmers but I looked and they can be $500+ (American here) I once had to pull...
  14. G54 Z offset? Avoid teaching every tool, every part?

    I'm a very basic operator at this point and I sometimes work with HAAS mills. Some don't have tool setters and even the ones that do might be broken or are just not used for whatever reason. There...

    I found another picture and wrote on it a bit. (Work on Monday and wont see machine until then) The back side of the tool is pulling out and the front is flush. The wedge is 2 pieces? One has 2...
  17. Thank you everyone. I was thinking I could...

    Thank you everyone. I was thinking I could manually program it with G01 as it's just a .015" roughing pass, leaving .005" for finish facing. But then I still need to learn G71 and G70. angelw, I'm...

    No, they didn't hire me to program anything. I've just been wanting to move up the ladder a bit and have been slow to do so. It's a Mitsubishi LT-350 with Navi and a M70 controller. It's got 4...
  19. Gcode, not learning canned cycles very well.

    Just wondering if anyone knew of a place to learn Gcode for the lathe. I've been trying to understand G71 and just don't understand it. I understand the approach and 1st G72 block, but it starts to...

    Turning, started to pull out tool holders?

    Noticed that the back of the tool holders were almost flush with the chamfer of the tool slot. (3/4" bar? Slant style tool lock?) I have been trying to learn how to program this lathe and was trying...
  21. Turning, Kissing into tolerance and chip breaker?

    Hopefully this sub-forums includes inserted tooling and not just a CNC machine as a tool.

    I've been painfully and slowly trying to pickup lathe and G code. The tools that this particular lathe...

    Mitsubishi M70 LT-350 P33 Format error

    I was trying to see if I could get a basic G code program to run on this machine. I was not... I'm actually trying to use a HAAS lathe manual to learn... Making sure the G code and M code both do...
  23. G code, what kind of math do you need to know?

    Sorry if this should have gone in the General sub forum. I usually think my posts can go in either...

    Now I know manual coding G code isn't so popular anymore, but I intend to start there. Do...
  24. Can a part off be used for a clean finish, cut to size?

    The part off we have for this particular machine is a Mitsubishi GY2M0200D020N-GM VP20RT insert. (.079" wide) Tool holder gyhrus12c00-m25r. Another thing is how do you do a soft part off? The...
