    Default Help with programming multiple offsets

    Hello all,

    I am new to programming using multiple work offsets. The job I am programming is using g54 - g59, 3 parts per vise, and I have attached a sample. The machinist told me each part has been indicated in and registered under the correct offset. When the program runs it locates the first part in each vise G54 and G57, but when it moves to the other offsets it is no where near where it should be.

    The machine is a Haas VF3 and I am programming with mastercam.

    Thanks in advance for any help!

    How did you program it. are they all the same parts and used transform with offsets?
