Mazatrol Tool Offsets

I am hoping someone on the PM form can give me some advice or help give me an understanding. I am fairly new to Mazatrol and Mazak machines in general, I purchased a 2005 QTN250MS with the 640t control earlier this year and have slowly been working on it to get it up and going. When I purchased the machine, I was lead to believe it had the ability to read EIA programs from a standard CAM system (like Fusion 360), but as it turns out that option was never enabled/ordered with this machine when it was built, I can apperently have it enabled, but cannot afford/wait to get that sorted. So, it appears I am going to have to get very good at programming in Mazatrol, but it should be able to do everything I need for now. I have a fairly good understanding and background with Haas/Fanuc controlled lathes so I know what I want this machine to do but I am struggling how to tell Mazatrol what I want.

For instance, I have some parts to make that require a 1 inch through hole and then that hole will get bored to size. I have a 1 inch insert drill and I would like to use the outside insert of that drill to rough bore the hole and then finish with a different boring bar. When I go into the Mazatrol tool offsets, it seems pretty simple to set up the tool as a drill. However, where I am confused is how to define a separate offset and tie it to that position. On say a Haas or Fanuc machine, you would define the drill as T303, so the machine goes to turret position 3 and pulls offset 03 from the control. Then to use a different offset to bore, you would call say T323 or something similar, where it will stay on turret position 3 but pull offset 23 from the control instead. The Mazatrol offset page only gives me the option to set 12 individual tools and they can be configured in what ever orientation needed, but I cannot figure out how to set separate offsets for the same tool position. The easiest solution to this problem would be to just drill the hole with the insert drill (say T1), rough bore with a boring bar (T2) and finish bore with another boring bar (T3) but I would like to save a tool position and tool change if possible.

Much like above, how would one go about setting two OD turning tools (One for the main, one for the sub) in the same tool position on the turret? I have read through manuals and tried to get an understanding but have hit a wall....if anyone would have some information (manuals, sample programs, pictures) I am all ears. Thank you in advance!

There are several ways to do what you want to do by drilling then rough boring with the insert drill.

Your control can set up multiple geometries and tool descriptions for each station. You go to the tool data page and scroll down to the insert drill and then you ADD a tool description to that tool. This will make tool 10 for example also have another tool like 10A, 10B or whatever letter you choose.

The drill description will have the X geometry as the centerline of the tool. To use it as a boring bar for tool 10A, the X geometry will need to be probed on the tool eye like a boring bar.

The second method is what I have to use on the older controllers that cannot set multiple tools for one station. I describe the insert drill as a boring bar and then probe the geometry as such.

In the Mazatrol program, I then create a manual process in order to drill the hole. The X position will be the drill diameter and NOT X0. After drilling the hole, then rough the bore with the same tool.

Thanks for the information, Phil. I took a look through the tool data page and machine manual and figured out how to set that up, to be honest it is kind of clever to have it set up that way so you do not get offsets mixed up that would be tied to a specific tool. As far as the programming goes, I will have to remember that trick in case I cannot get the offsets to take for what ever reason.
