Hi All,
Well my neighbor, who has a TV repair shop,  may deliver a pulse generator tomorrow which will allow me to simulate a pulse to use along with my timing index.

Chip, you may not standing alone.

General Mach Discussion / LATHE TOOL TABLE

« on: May 14, 2009, 06:05:13 PM »

Just a few lathe tool table questions.

1. Any reason why you should not use tool #0 as the "master tool " when setting up a tool table for the lathe?
   

2. The T word   Txxyy    the xx is the tool number, so i assume that the if yy was 10 it means the offsets for tool #10
    will be used to for tool # xx. Correct?

Joe,
Yes you will need to puchase a license for LazyCam. You get a lathe modual in LazyCam.  There is very little documentation and Lazyturn ( which is in developement and maybe will be
Beta released a few months , near future whatever that is ) will replace the LazyCam Turn modual. If you have
a license for LazyCam it will apply for LazyTurn.

My opinion is  Lazyturn will be worth every single penny spent for a license as no other program will touch it come near it, for ease of use, graphics, even as now restricted, and a complete manual on using it will be available. That's my opinion for what it's worth. You can take a look at the current manual in the Members DOCS. I strongly suggest you look and search on your owne and make your owne decision on lathe software.

Yep, if you have the time and effort you can hand code stuff. The lathe can be a pain to hand program, but for some simple stuff the learning will serve you well.

Dave,
I only think i know what your talking about and that is the problem with what you chose to do and now you expect support for it. Sorry my friend. Not from me.
That said, you will need to learn how to modify the post processor. I have never needed to do that as
support is available along with the product if you know what i am talking about.
If i am wrong in my quess, then correct me and my appologies, if not my time needs to go somewhere else.

Hmm......Sorry about that, yep just the mill stuff and i didn't include anything for the lathe in the listing.
You basicaly  have only the wizards that come with Mach /Mach turn and a another thread cutting add-in
 is available, also Lazycam ,and Lazyturn which is being developed.
You can use LazyCam Turn, but to post you will need to purchase a license, you can use Lazturn and it will post roughs only, or  use the combination of the two.  There is not a lot of free stuff out there for the lathe that is worth much. The lathe porgrams out there are rather expensive.
Welcome to the learning curve of CNC turning.

If you go to the Mambers Docs you will find a listing of all the Wiazrds with pictures of what they do.
FWIW
RICH

For parting off, just locate the cut off tool and put a G01 X ( distance ) F ( feed rate ) and maybe a G0 to return the tool to were you started. For a simple taper you can do an G01 X (DISTANCE ) Z (DISTANCE )
F ( FEED RATE ) combination move.

Dave,
You need to get from Mastercam or modify  so you have the correct post processor as ostie01
mentioned.
Different programs may generate  the "F" or in you case "E"  for the feed rate differently.
Don't be suprised if you see other things like a G33 for the threading and inverted X and Z's
from other porgrams.
 
Sort of like two Cajun's speaking  French and they don't even understand each other.
No demeanor intended!

General Mach Discussion / Re: Timing

« on: May 13, 2009, 07:59:09 PM »

Ianh,
Mach needs a pulse duration that is long enough to read, so, the faster you go the bigger the slot required relative to disc diameter.The electronics associated with it all has some time also. So I would consider what is in the manual a good ball park calc for the width.
Don't remember, had the same problem of reduced display at one time, but one of the versions cured the readout with no change in the slot width as per calc. This was for a single slot for index.

The four slotted timing disc i use has three small per calc and one twice as big and works fine.
I'm using Ver2.042.27 for the lathe FWIW.
