Stock on facing

Is the top of your part Z zero?
It's kind of an industrial standard thing that's worth working with until you know better ;-)

Yes the bottom left corner is set to zero. I can send you the file to have a look.

This is confusing as magicniner asked "is the top of your part zero" and you said "yes" and then said left bottom corner is set to zero!!

The normal way to start is to use the top of the part as Zero and any movement below that becomes -ve

Well it's the top of the stock but in the corner. So it's still the top it's just I prefer my zero position in the corner.

Also the facing operating is removing the correct amount off the stock it looks like the pocket operation after isn't taking that into account.

Your Stock is not your Part, that kind of confusion will result in unexpected depths of cut when you incorrectly interpret the terminology in your CAM package :D

i know its not but ot shoudl take into account the stock is thicker than the part and the take .45mm off the pocket if the stock has been faced.

the first operating is a face to remove .45 and the next is a hole pocket and the operating after is to pocket 2mm not 2.45mm. On the simulation the z moves down to 2.45mm

You are mixing things up and trying to make the CAM work the way you think it should.
It's obvious that you are taking .45 off your stock but referencing your pocket depth as it would be from Top of Stock but your CAM is taking it from the actual Top of Part.
Setting Top of Stock as Top of Part is the source of your issues, you'll have to work out how to juggle the numbers in CAM to deal with that, a spreadsheet would help in keeping track of the differences required ;-)
