Boss brings another piece for me to learn on today. Happy Happy Joy Joy.
Anyway, the plate is .300 thick and 12.000 diameter. I laid the plate down on the cmm with the origin hole( per the drawing) ( which is at the bottom area of the plate) facing me at the front of the machine.Note: all holes are in the Z axis. The drawing indicates the hole pattern is realitive to the center of the part . However, all locating dimensions come from the origin hole. Well. I leveled the plane with 3 points, but how do I align the rest of the part? There is a hole at the top of the part, which is in line with the origin hole at the bottom for a Y axis. There is group of holes that are in the X axis just above the origin hole. My thought would be to level Z, construct a line between the top hole and the origin hole for Y ( rotate), and then construct a line between the far left X axis hole and the far right X axis hole to origin. I did this , but the origin location on the screen didn't put X,Y,Z at the origin hole location. So I called alignment back up and called circle1 ( origin hole) to X,Y. origin. The origin was placed at the origin hole on the drawing, but I am not for sure this is really right.
Setting the part up on the layout plate, i would insure the origin hole was at zero in both X & Y axis, as the Z would be 90° perp to these, and then start measuring. Well, thanks to all that can help. I hope this is not too confusing. This is really a piece of cake job to someone who can use the machine properly. Thanks again.
