Cad=part

I tried to make a program just off the cad model without c=p. Luckily I found the sample part, I tried running the program and after the manual alignment the probe moved about an inch off the part and tried to take the first hit. How do you use read point, maybe this is my issue?

So a readpoint is simply a theoretical point that you create in order to help start your program. its placement helps determine where the probe goes for your first feature to inspect. it determines where the operator should manually move the probe at the beginning of the program.

the READPOINT eliminates the need for a 3-2-1 manual alignment on just about everything.


what I LIKE TO DO, since i have the freedom to orientate the CAD model anyway i see fit, i try to keep it consistent. i translate the model so that X+ on the model is X+ on the machine and so on and so forth. remember, your initial alignment doesn't have you be your final alignment, it's just used to give the machine an idea of where the part is on the granite.

so i orientate the CAD MODEL to match the way i have the part oriented on the machine. your RP can be anywhere on the part, but i like to usually use a feature that is well defined, like a particular circle, or corner point. when I translate the part, i usually try to put the CAD coordinates right where my first RP is going to be.

place the RP in the program, and manually input the x,y,z coordinates as 0,0,0.
create an alignment using your RP as x,y,z, origin. make sure your vector is correct.
if you are at A0B0 for your probe, and you are working in the zaxis, make sure your vector is 0,0,1.
or as you see fit.

make sure before you create your RP, that you put a OPER note to place the probe as closely to your designated starting feature as possible.
