This afternoon I tried cutting a rectangle with a circle in the middle.
The machining is very smoothly as you can see from the photos.

Now I ask you a few questions.
1 - why in MDI mode, when I type G01 Y-60 F1000 milling shifts the Y-60.0547 and G01 X-600 F1000 milling shifts the X-600.0199?
Here are some photos.

and I encounter the same problem with the machining of the part above.
in the program there are G01 X-120 F700 and the machine shifts to X-121.12.
that the dimensions of the part is not good agreement, but normally when I type in MDI G01 Y-60 F1000 machine must stop at Y-60 why it does not?
2 - How to reduce speed rapid traverse G00?
PS: For my settings automatic I use calipers square is what it is or should I use a dial indicator tip?
thank you in advance for your help
