Hi, I am pretty new to operating/setting up CNC machines. I run a HAAS VF 40. I tend to get a little confused when adjusting my Y after the first part has been ran. Can anyone explain this to me I work in a small shop. Im the only white guy with about 4 Mexican guys (great guys) and there is a bit of a communication barrier. I get that there is an imagined O with a +/- side. I believe toward the back is the - side and toward the front is the + side. Lets say I ran my first part and checked it. The part is supposed to have a hole directly in the middle of the part. After using my calipers I realize the hole is off a little. It seems to be a little more to the back of the machine. I know to get my reading on the caliper say it's .30 out of spec I would divide by 2 that would make the number .15 I guess my question is would I add or subtract the .15 to my work offset in the machine? If anyone happens to have any tips or internet resources to make this a little less confusing they would be greatly appreciated!
Thanks
Thanks
