Looking for some Haas HL-2 lathe help

Morning Everyone

Looking for some lathe help.   I hardly have any lathe programming experience.

I sm trying to help out a friend who runs a local job shop and his programmer bailed on him and he asked me to help him out in a pinch.  Anyway, he has a Haas HL-2 and I’m trying to program a simple part with a “v” profile.  I got the toolpaths  looking good however when I backplot and post out, all my “X” values are negative when then should be positive. 

I have the WCS as +D+Z (TOP) and the toolplane as Lathe Lower Left (TOP).  Pretty sure this is my issue however I can’t get it to change toolplanes and regen.

Can someone point out what I’m doing wrong and point me in the right direction?  Any help would be greatly appreciated.

FYI, he’s using X6.  (I know, I know dinosaur version)

I attached a screenshot of the backplot and the position display.

Thanks ahead of time.

You don't change planes you change the Axis combinations in lathe. Yes it should left upper not left lower. Really surprised that Axis combination showed up in the default HAAS lathe. You should see an Axis combinations button in each operation on the main page click it and change that. Then regenerate and repost and you should be good to move forward.

Thanks Millman.  I will try that when I go over to his shop after work.

So I have my toolplanes correct but the axis combination is screwed up?

The next time I do a lathe program, should I setup the planes first and then move my geometry?

Top plane is all you normally need. I am sorry I don't use the WCS method for lathe programming. I always move my geometry to TOP and go from there. Unless you are doing Milling you don't need any other planes for Lathe work. The only time you would need a copy of the top is if you are doing sub spindle work and you would set your G55 Zero up for that plane and go form there. Now if you are doing milling then yes you will need planes, but they all should start from TOP if you do it like I have mentioned here. If you do use the WCS process I am not going to be much help.

Thanks for the advise.  I will have to keep practicing.  trial and error.  I'll have to try it the way you described.

I appreciate the guidance and input.

Using the Mastercam default Haas post for a tool room lathe; you may find that the post has been set up to have the tool in the 3rd quadrant  -X -Z.

The post will output +X this was done for users to visualize the tools as they are on the machine.

Joey,

I just ran into this same problem trying to make code for a Haas TL-3. I was using planes as WCS:TOP and CPLANE  TPLANE as +D+Z. It occurred to me that I had all my tools set up as top turret and all my entities were on the top side of diameter zero (which is our programming standard for our Hardinge Conquest slant bed). Once I moved my entities to the bottom side of diameter zero and set up my tools as bottom turret, the code came out with X values as positive. A call to an In-House Solutions rep confirmed that indeed this is the proper procedure; he said to make my toolpaths on the screen as they would look on the physical machine.

[in a toolpath process, click on tool to edit, then click on "Setup Tool..." and change turret to bottom]

This appears to be what Allan refers to in his post.

Thanks Rick

I will have to give that a try.  I don't have a lot of lathe experience so I need to just sit down and play with it a lot more.  Thanks for your input, I appreciate it.

You're welcome Joey.

A quick search of HL-2 reveals to me that it is a slant bed with top turret; therefore, the information I gave may not apply to your situation. You could still try it anyways, and see if it brings the result you're looking for.

Good luck
