Setup Reduction 101: Core Tasks Vs. Total Setup Tune

摘要

When teaching setup reduction, one of the first principles I try to explain is related to what I call the "core tasks" required to make a setup. Core tasks are the physical tasks a setup person must perform in order to get the machine ready to run production. For atypical CNC machining center, these tasks can include (among others): 1) Tear down the previous setup and put everything away. 2) Make the workholding setup. 3) Determine program zero assignment values. 4) Enter program zero assignment values (typically into fixture offsets). 5) Assemble the cutting tools. 6) Measure the cutting tools. 7) Enter offsets for the cutting tools. 8) Load the program. 9) Run the first workpiece. 10) Inspect the first workpiece and, if necessary, make adjustments. 11) Repeat the last two steps until the workpiece passes inspection.
