y axis exceeded message

[Black Forest]

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.

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.....

[suntravel]

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.

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

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.

[Black Forest]

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!
