Works in progress / Re: 3 PAGE LATHE SCREEN - WIZARD ADDITIONS

Hi Wes,

I am in diameter. Are you saying that it will always do moves of half a circle? If so then the tool path was misleading - I saw it doing half circles and thought I will get the half circle in the part, but it appears to me now that part of the move will cut air. Will try to cut some material and see how it works.

Hi Amir,

Glad to see your machine is finished. And the part looks beautiful.

Just tried to cut air. The tool would dive right into the stock, following the arc. Needs a few roughing passes based on the X start and final X. May be the rough passes should be G1 and only a few last passes would be G3.

The Z start and end are still swapped.

Also, the X start and X end don't seem to be defined correctly. X start should be the initial stock diameter. X end should be how deep you want the arc in the workpiece, i.e. not always would you want half a circle (this is what the current code keep doing).

Thanks Tweakie. This one seems useful. Will remember to check them when I will be doing a control panel. Got a link?

Wes,

Yes, appears my arcs where set to absolute rather than incremental. Don't know how it was not affecting any of the other programs I was running. Changing it back to incremental fixed it

Most industrial lathes only use the T word for a tool change. This is how Fanuc works and this is why Mach3 was changed.

Hmmm... Looks like some setting here. But then, just checked the other arc wizard and it shows a nice tool path with reversed arcs checked.

Will see if the incremental arcs may be affecting it, though it doesn't look to be the case here...

Another note. I like my programs in feed per revolution, but I work a lot from the MDI as well where I need it in feed per minute, since often the spindle is off. Sometimes I forget to program G94 after the program and commanding a move in the MDI with a feed like F100 results in a rapid move. Can the Gcode have a G94 in the end?

It may not be convenient for people working in G95 from the MDI, but at worst they will get a very slow feed if they forget to do a G95 after the program. I think it is better than a rapid into the workpiece.

Wes,

Attached are the screen shots and the corresponding Gcode.

The syntax for a tool change in Mach3 has been changed years ago, not requiring the M6. Tool changers don't require it neither. I have a tool changer and I only program Txxyy and it knows to refer to the M6Start macro.

Ok Dan,

Give this a go... please be careful as it needs to be tested before you can rely on it. Also Mach does not display the stock correctly but the cuts look ok from the DROs. I would recommend cutting air a few times before using it to do any work.

Wes,

All the other wizards work with "Reversed Arcs" checked. This one seems to require it be unchecked - otherwise the arcs look a mess. Anyway, it cuts a convex arc (like OD Arc 3). Also the Z Start and End (May be should be changed to Z Centre..) are swapped.

The gcode file puts out TyyyM6 for a tool change. The M6 needs to be omitted.
