This is embarrassing. I can not figure out why my Y axis is exceeded. My mill has a small work envelope of only X500mm Y250mm Z400mm. The contour of the part is only 160mm wide. I set the part zero in the center of a bore that will be there later. Right now I was just trying to experiment to see if I could get the contour correct. As in not really cut the part by having a shorter tool in the spindle than what is in the program. As soon as I start the cycle I get a message that Y- axis is exceeded. I might not have my part Zero exactly in the middle of the future bore but it is within a few mm's. Would that make a difference? The bore is not programmed. I created the program by importing a .dxf from Fusion and using the contour feature to create the tool path. Attached is the icn file and my report. Also a picture of the part I want to "mill".

I didn't put any cutter comp in the program. I just wanted to see if I could get the outline of the part programmed. SPFD!!!!!

You have a travel from y-84.5 to y+75.5 in the .icn file

If you jog to Y0 in G54, what is the position in machine Y ?

ALT D will switch the DRO from G54 to Machine.

Uwe

In the report G54 Y0 is at -124.53625 with -250 limit this must work...

Pictures of what you asked for.

This time is showed X axis travel exceeded.....

Don´t ask for Y if you mean X

0x G54 = 127,17 + 396,35 from ICN = 523,52 mm
Travel Limit is 500mm, can`t work.

Uwe

But I know nobody starting with CNC milling not running in traps like this

You can not mill around a 500mm part with 500mm travel.

Travel must be at least 500mm + Diameter of the mill+ some space for positioning.

Divide the work in 2 sections, or find 20mm more travel in X

Uwe

You'll never be able to make that part in one setup on your machine. You have 500mm of X travel. You have a 500mm long part. You would have to use an infinitely small end mill to cut the profile. You will have to machine the outside of this part in two setups.

Then I used the wrong .dxf because I shortened the part 10mm to account for the 500mm limit. I will try again with the correct .dxf. Or I will figure out how to do it in two setups. Or buy a bigger mill!
