Fusion 360 Turn: Tool location/position

[Richard Evans 2Participant @richardevans2]

Hi All,

I have a bit (not loads) of CNC experience and I'm investigating CAM for turning in F360. All the videos I've seen show the tool position as being behind the workpiece, and when I add a tool in my test project, that's where it is. I would like the tool to be in front of the work, where it is on my lathe (Denford Orac) so that I can clearly see what the toolpath looks like in simulation etc..I can't find a way of doing this.

I can't get my head around the tool at the rear (I know rear-mounted tools are used!)- surely Fusion isn't expecting the lathe to run in reverse?

What am I missing? I can change so much in Fusion- why not this?

Thanks for any advice,

Richard

When you do the setup of the stock make sure X is facing towards you then the tool comes up on the correct side. You can also edit the tool for forward or reverse rotation

Should then cut like this view rotated as if looking fronm rear tailstock end.

When you select the tool use the Setup option in the Tool menu to orientate the tool correctly, you can Edit the tool after selection if you need to change anything.

Also when completing the work setup you can Flip the WCS direction for Z and X axis.

Thanks Jason and Emgee- that issue seems to be sorted.Now something else (of course). I have a simple test piece- just a conical shape. The simulation looks fine in Fusion, but in Mach, the shape is wrong and there are loads of large loops in the toolpath. Any idea? Obviously, I'm using the Mach 3 Turning post in Fusion.

As an aside, it's the first time I've looked at Mach for a while, it looks pretty dated compared to modern software. I use it regularly on the Triac mill, but these are routines I wrote years ago using Sheetcam, I haven't tried to do anything new in Mach fora very long time!

Thanks again

Check which mode, Diameter or Radius, the program is written in matches the setting in Mach.

Thanks Emgee, but that didn't do it.

I sorted it by going to Config-Ports and Pins- Turn Options, and unticking the 'Reversed Arcs in Front Posts' option. This apparently is related to the front toolpost location as distinct from rear.

Now I just need to sort out a few options and settings in Fusion…….
