Thank you for your reply

They are in 3D but that is summed just the same.
If the G-Code is basic enough to import: menu CAM .. G-Code import...
Cutting and traversing are on separate layers.
OK, thanks
Rounded to two digits.
wycinanie frezem 44.cnc: traversing in 193 moves with a total length of 1446.38mm.
planowanie 44.cnc: traversing in 193 moves with a total length of 817.33mm.
Both cut 193 paths with a total length of 1086.58mm at FEED 60.
Traversing paths are reduced to 56.51% for the second file.
Remember that traversing is done in G0 mode or with the highest X/Y FEED available.
Diagonal this even exceed these FEEDs because for example Fmax1000 in X and in Y is about F1414 along the trajectory.
OK
This doesn't account for plunge down and retract.
For this we need to investigate the G-Code:
It retracts 193 times in G0 mode from Z-1.6 to Z10 or 193*11.6mm = 2238.80mm.
And it plunges 193 times in two steps, first to Z0.08 in G0 and then further down to Z-1.6 in G1 F600, again 2238.80mm.
If allowable the most gain in travel that can be made is in plunging down and retracting.
If the cutter doesn't collide with anything at lets say Z3.0 the vertical movements can be reduced to 1775.60mm instead of 4477.60mm.
The gain is here much more pronounced then with optimizing Start/End.
OK
I think that most machinist and businesses are interested in the estimated cutting time and not in the traveled distance.
This is even harder to estimate because we need to account for acceleration and deceleration time.
Fine, true but cutting parameters are actual not in my scope, but I understand
@ ha4n: May I remark that the plunging FEED is 10 times the actual cutting FEED.
In the end this will kill your cutter as it is slamming in full cut on your workpiece at 600mm/min.
Usually it is reversed: cutting FEED 600, plunging gently at FEED 60.
This kind of aggressive entry strategy may be required for surface hardened materials ... For the first handful of microns.
I check my cutting paraneters and will back to you
