HAAS ST-25Y Lathe live tool shaft splining

[BBMachining]

I have a 1.500" aluminum shaft that I am trying to cut a linear spline. I have tried both a 2D contour and a Trace, then using a circular pattern, duplicating the tool path around the part. My problem is when fusion posts the tool path, it homes the C-axis in between every spline. During a 35 spline program, wasting 8 seconds in between each spline due to the homing, it using up a ton of extra time. Does anyone have a fix?

Could you share your file, or a sample file?

Try checkin the Optimize C axis selection to Yes in the post process dialog.  That fixed this same issue for us.  It would constantly turn the brake on and off between every line of code.
