G114 Polar Interpolation
Hi All,
I've been using Fusion to write programs for our mill turn lathe with C axis control and so far everything's been going great. I've been trying to write a program for the part shown below and have managed to get a program that functions and produces an acceptable part but I have some concerns about it. When using the C axis and X axis of the machine together to produce the triangular profile at the back, the C axis performs a lot of stop-start actions instead of smoothly moving around the profile.
We've machined this part previously with a program written in some different software that uses a G114 cycle and produces a smooth path around the part a much shorter amount of code. Is there an option I'm missing in fusion that will produced a path using G114 or a smoother path at least. I've attached the f3d, the segment of code for the triangle area and also a copy of the post we're using right now, any help on this issue would be greatly appreciated!

Hi Rachel does the machine have a Y axis? if it does then your previous post may have been selecting the y axis and not the c, the c axis by default will have to post lots of positions and code to maintain accuracy.
Having a quick look at the post
///////////////////////////////////////////////////////////////////////////////
// MANUAL NC COMMANDS
//
// The following ACTION commands are supported by this post.
//
// partEject - Manually eject the part
// transferType:phase,speed - Phase or Speed spindle synchronization for stock-transfer
// transferUseTorque:yes,no - Use torque control for stock-transfer
// useXZCMode - Force XZC mode for next operation
// usePolarMode - Force Polar mode for next operation
//
you may be able to force the use of the Y axis hopefully giving you a better program

Hi,
Thanks for your reply, I should have specified more clearly that our machine doesn't have a Y axis so must achieve this shape with X and C axis moves only which it does do so far but with a lot of small stop start motions.
