I am running a turning job in annealed tool steel - 18mm diameter bar. The part is about 2" long and a little over 1/2" in diameter. Currently it takes 1 minute 56 seconds. I am looking to improve the cycle time. The program is made in VPS. I have made a few manual modifications, but I am sure there are lots of little things I can do to cut the cycle time. When I looked at it now on the computer I noticed the OD roughing cycle cuts lots of air where it already faced of the part due to the finish OD cycle doing the finish facing too. Any ideas are welcome, but be specific , my G-code skills are not epic.
I am running it in a NLX 2000 SY. I have attached the whole file too.

I have noticed one place in particular where improvements could be made: When going from the roughing cycle to finishing cycle with the endmill:

I have shaved about 4 seconds in total with shorter lead-ins for the turning and removing the imaginary toolchange between the milling rough and finish.
I am sure there is more to save with more quick M-codes, but the manual is not too detailed about what can be used where. The time hogs are really the transfer and the work unloader. Those takes up 20-30 seconds.
