A CNC programmer is creating an NC Program to simultaneously machine the front and rear stations of a part using a dual station vise. They notice that the different tools are being used for the work offsets for both setups, and that the tools are running each work offset sequentially. If they wanted to save time so that both tools are used simultaneously in both setups using one program, what would be an effective option?
