The critical note is that the machine controller will record the exact location of the machine when the offset is entered, Figure 9-26. 9.10.2 Setting WCS on Control Once the machine’s spindle centerline is sitting directly over the X- and Y-axis programmed zero locations, that location needs to be recorded into the Work Offset page. On this Haas Machine control, Figure 9-27, the Work Zero Offset page is directly below the Height Offset page. Different controllers place Tech Tip In the program planning stages, ensure that your work- holding is repeatable. If the material can easily be placed back in this same position on the machine with each subse- quent part, this WCS only has to be set once. Goodheart-Willcox Publisher Figure 9-26. The X and Y axes intersection can be determined by finding the edges. Goodheart-Willcox Publisher Figure 9-27. A Haas controller with the tool offset page and work coordinate offset page.
