So im working on this part, and im trying to use the level rotate and origin alignment. I understand which vectors to level to and rotate too. However the machine isnt correctly reading where the part is after i allign it. Am i supposed to find the origin offset of each origin and offset it too that? like click on the cad for the Yorigin and enter the negative value in the origin box? Im also trying to use CAD=PART. Ive been programming 2 years, have mastered iterative aligns but barely use the level rotate and origin align but it seems like the programmers im learning from arent comfortable with using it either
You can either set your trihedron location in the cad system that the model was designed in prior to importing into pc dmis.
or...
Open pc dmis. Import your model. Go into Operation/Graphic Display Window/Transform. This will open up the model transformation box. This will allow you to move your model around your trihedron in pc dmis and will set the location of your trihedron so you can begin programming normal to how the part will be sitting on your CMM. Use your graphics view buttons to see how your model imported (meaning which face of the model imported in at Z+, Y- etc....) and then translate or rotate and you see fit, hit apply, then okay. Then begin programming. If you need more help, PM me. I'll send you my number if I have to in order to help walk you through this.
So even without using CAD=PART, okay so I take my plane, my line, my point on a given part. I align it to the x-y-z vectors correctly. What am I not doing correctly ? Am I supposed to be offsetting an origin to the points I am taking from the cad?
the cad is in car body, trihedron is snapped in. I can perform an iterative, and after an iterative I can perform a base align, I just cant perform a base align and then get the machine to know where the parts are at
miles.c There are no hard fast rules as to what you need to set the origin to or what to offset. It all depends on your dimensioning needs.
You will need to level to a feature
You will need to rotate to either a feature with an axis(a line or cylinder) or to two features representing the ends of an axis(like the I.D. of a part and a timing hole).
You will also need to set the origin to, a.k.a. translate to, a feature for the X, Y, & Z axes. It can all be the same feature or one feature for each axis.
After that, it would depend on the print what offsetting or rotating you do with the alignment. It should all be driven by your reporting needs per the print.
