Setup: Definition • The setup includes everything, all elements and time from the last good piece of the previous job until the first good piece of the next job. • In essence, Setup considers the ACTIVITES and TIME SPAN from GOOD PIECE (A) to GOOD Piece (B)
What setup reduction is not • Not to reduce set-up people • A 50% reduction in setup time will not lead to a 50% reduction in setup people. Typically no reduction in setup people. • Not to produce more product • (except when capacity is a issue)
WHY Reduce Setup times? • Key reason is to Reduce Lot Sizes • Reduced WIP • Reduce Lead Time • Better Quality • Flexibility
Preparation, after-process returns, and checking of raw material, blades, dies, jigs, gauges, etc. Mounting and removing blades, fixtures, chucks, etc. Centering, dimensioning, & setting of other conditions Trial run & Adjustments 30% 5% 15% 50% Work Content Breakdown Ex.
Two Kinds of Setup Activity • Internal • Can be performed only when the machine is shut down, or process is not producing. • External • Can be performed while the machine is running, or process is producing.
Fundamental Rule • If an ACTIVITY can be done with the process is running (externally), then it should be done while process is running.
Where to Start • Bottlenecks • Short Lead-time • Customer Complaints • Delivery
Guidelines & Tips • Review and Document current layout & process • Data Collection • The complexity of the job change will determine how many observations needed • View complete change over whenever possible • Simulate change over when feasible • Video Record • Process Map • Fishbone
Guidelines & Tips • Evaluate process, look for possible enhancements. Incorporate the operator, supervisor, processor, setup person, etc. in the evaluation. • Separate internal and external activities • Reduce internal activities by doing more work externally • Brainstorm for improvements
Guidelines & Tips • Reduce/improve both internal and external activities • Internal • Standardize Fixtures • Locating Pins • Standardize die heights • Predetermined X-Y coordinates in CNC machines • Standardize & improve clamping methods • Reduce the number of bolts
Guidelines & Tips • Standardize bolt heads • Cut off unnecessary threads • U-Washers • SPC - Pre-control charts • T-slot and U-slots in base plates • External • Eliminate adjustments - potential 40% to 50% • Maintenance of tools, gages & fixtures
Guidelines & Tips • Preset tools and position dies • Assign additional people to setup when feasible • Pre-stage all items - Die carts, tool boards • get tooling, fixtures, dies, and molds • Dismantle and repair items • Clean up • Return tooling • What paperwork/necessary computer information • Reduce internal activities by doing more work externally
Guidelines & Tips • Coordinate and plan external work • Create a Setup Chart • Color code fixtures and tool • Code location and description of dies • Locate storage as close as possible • Start preparation before the last part is run • Plan for extra manpower
Guidelines & Tips • KEEP AN OPEN MIND, ASK “ WHAT IF” • Test ideas and measure results • Implement improvements • Document the new process
In Conclusion • Quick reaction to the DEMANDS of the market is critical. The ability to give your customers WHAT, WHEN & HOW MUCH they want is essential. Efficiently changing from one job to another job is a MUST.
