SMED is Continuous Improvement It is a customer driven requirement. Customers are demanding: Product and service diversity Lower costs Higher reliability and quality. In essence organizations need to become leaner ! So organizations must: Produce smaller lots, more frequently. Expand the scope and diversity of products and services. Reduce quality defects. 4 Ultimately, SMED focuses on reducing changeover and set-up times, thus enabling organizations to: Produce smaller lots of products and services more frequently !

Develop a broader scope of products and services ! Reduce quality defects towards zero ! Meet Customers Expectations ! 5 What Does Set-up/changeover reduction mean for my business? Increased customer service levels and profits ! Via Waste Elimination resulting in: Reduced Lead Times-Faster Delivery Zero Inventories-Reduced Working Capital Improved Quality Improved Safety Smaller lots of products-flexibility Diversified Product & Service Options 6

Why SMED ? Look Familiar ? To eliminate the wastes that result from uncontrolled processes increasing inventories and lead times.. To gain control on equipment, material & inventory. Apply Control Techniques to Eliminate Erosion of Improvements. Standardize Improvements for Maintenance of Critical Set-up Parameters. 7 Tool Kit Comparison Major Tools

turned off. Completed products are transferred to next operation. Raw material is moved after the machine is stopped. Detection of defects or missing equipment is noticed which the machine is running. Setup tooling delivered after the changeover has begun. Defective product identified after internal setup has begun. Defective tooling,fixtures, setup instruments are noticed after the machine is

turned on. The operator notices that equipment is missing after internal setup has begun. 12 5 TraditionalSetup Steps Defined Preparation - Ensures that all the tools are working properly and are in

the right location. Mounting & Extraction - Involves the removal of the tooling after the production lot is completed and the placement of the new tooling before the next production lot. Establishing Control Settings - Setting all the process control settings prior to the production run. Inclusive of calibrations and measurements needed to make the machine, tooling operate effectively. First Run Capability - This includes the necessary adjustments( recalibrations, additional measurements) required after the first trial pieces are produced. Setup Improvement- The time after processing during which the tooling, machinery is cleaned, identified, and tested for functionality prior to storage. 13 TraditionalSetup Resource Consumption Analysis Setup StepsSetup Type

Combining equipment functionality Involves standardizing the equipment ( parts, tooling, processes) based on commonality between setups to reduce the number of setup steps and cycle times. The common setup parts were identified and By using these fixtures, the parts are automatically centered and adjusted for height and flatness as a part of External setupnot Internal setup.

replaced with this jig/holder combination. Notice how different quantities of the same part can be setup with the same fixture. Also, these setups can occur while the machine is running. 17 Waste associated with finding, replacing, motion will be eliminated by this example of visual placement. Tooling supplies are clearly labeled

Tooling supplies are neatly assigned a unique location. 18 Phase 3: Reducing setup processing time. Elimination of Bolts & Adjustments. Example of One Step Fastening Bolt attachments requires 32 complete turns for each bolt or screw (1 for each thread) to fasten this bolt and die to a machine. This clamp attachment requires one

step to attach the die to a machine. 19 SMED for the Workplace Tr How to Use This ManualThe continuous improvement tools that are presented in Sections 1-10 of this manual are shown in order of use.
