My situation is that factory has purchased vinyl-wrapped doors and drawer fronts from Laminex already cut to size. We don't need to nest or cut the parts. We only need to generate CNC drilling programs for hinge holes, drawer front drilling, handle drilling, etc.

In Processing Center, I can generate and view the Single Part G-Code Results. I see the parts listed and can preview the machining operations, but I'm struggling to understand how the machinist know which drilling belongs to each part and where exactly to locate the part? 

Is that how people normally drilling gets done if parts are already cut? 

Also if these doors were setup as buyout initially can be changed to board from the work order summary?
