Hey everyone. doing a lathe setup in fusion 360 and everything is cutting towards the chuck which is good, however when I cut normal right hand threads, the tool is cutting away from the chuck and I don't want to pull the part. does anyone have any thoughts on this? Im trying to cut 3-1/8" UN threads
You've defined a RH tool and RH threads? If those are both correct, it should be cutting towards the chuck. If it's not, could you share your Fusion file so we can see your settings?
File > Export > Save to local folder, return to thread and attach the .f3d file in your reply
You had the "Clockwise Spindle Rotation" turned off.
Assuming you ARE using a RH tool, you'll want to turn that on and define your tool as a RH. Travel will be into the chuck
Ok we were able to get the tooling to move towards the chuck but we are still not getting threads to show? Given we know the tool holder we have shown holding out insert may not be correctly drawn since we modified it to be similar to our actual Iscar tool holder but we still aren't getting threads to appear. see screen shots below.
In your toolpath. you have your pitch set to 12 inches and then your tool is defined as a .012" pitch. Neither of those are going to get you good results. Let's change those to be correct and see what we can see:
1/12 = .08333
To calculate the pitch (in Imperial), it's just 1 divided by the pitch.
