Generate CNC G codes for OD and ID Machining

A handy tool to generate CNC G codes with just a few number inputs. It works with different OD and ID machining scenarios:

- OD Angle into Radius,
- OD Radius into Angle,
- Angle to Angle Compensation,
- OD Chamfer,
- OD Radius,
- OD into Radius to Step

- ID Angle into Radius,
- ID Radius into Angle CW,
- ID Radius into Angle CCW,
- ID Chamfer
- ID Radius into Shoulder,
- ID Radius

User can choose to copy and paste generated G codes to clipboard or email the G codes or save a screenshot by simply tapping a button.

How about an app for ID work?

Works very well for quick code. Perfect for job shop use, one off parts, soft jaws, etc. I only wish they (or another developer) would make an app that calculates g code for ID work.

Absolutely worth it. Best $4 I ever spent

I really really like the app I do wish that there was a OD “radius into angle into radius” It’s capable of doing this but there 2 separate functions I think there should be a option that you can do both in the same section. Also would like it on the ID as well. But you can make it work iv had to program stuff for the ID using the OD function and then flop the numbers but hey it’s way easier then figuring it all out by hand. Wish I woulda had this 10 years ago. Very well done and would definitely spend the money on it again and again. Well worth it.

Very very good app

Sense I don’t have access to Gibbs or Msstercam and I am programming at the machine this app has been perfect. I use it everyday and highly recommend it for anyone that is programming at the machine or you don’t have Gibbs or Mastercam to work with getting the codes needed for basic od turning.
