Using Fusion for my Swiss lathe

[tonyFTPQQ]

I am constantly getting code for use on our swiss style lathes and altering the g code to run. Thought I would start to alter a post to do some of the work for me. 

How can I make the post flip all the Z directions? I need all moves that were Z negative to be positive and vise versa?

attached it the post I am starting with, thank you.

You're in for a lot of work. I'll attach the post I use for my Swiss with a Mitsubishi control, it may give you some ideas.

My machine has a B-Axis so there's a lot of functionality built into my post to make it all work correctly. In my tool library I designate the tools like this:

OD Turning tools Main or Sub - Turret 1

B axis tools(live or static) for $1 - Turret 2

Axial tools for $2 - Turret 3

Radial Tools for $2 - Turret 4

Best of luck!

This may help. Seems to be a lot more comprehensive than mine.

Hey Brandon,

Any idea what it would take to modify that to work on Nomura NN32YB2?

[BrandonTBFBF]

Unfortunately I don't. Those machines are all so different.

You could always use it just to generate tool paths and hand code the rest.

Thanks for the reply. Thats what we currently do and looking to eliminate the hand coding.

In the work setup:

Choose "Secondary Spindle" instead of primary spindle. This inverts the Z-Axis when posting code. Use this method to manipulate the post for swiss turning centers. Typically I'll use the Tsugami M08SY as the post processor. See depiction below...

Be sure to backup your post before making any changes..

Find this line in your post:

var zFormat = createFormat({decimals:(unit == MM ? 3 : 4), trimLeadZero:true, forceDecimal:true});

Change it to:

var zFormat = createFormat({decimals:(unit == MM ? 3 : 4), trimLeadZero:true, forceDecimal:true, scale:-1});

The "Scale:-1" will invert the Z axis coordinates. If your sub coords post out in reverse, look for this section and flip the "Scale" value for the Z axis and/or any others to match what you need.
