SMED Implementation, Step - 3
"Convert internal setup activities to external setup activities"
As detailed in my last blog (Link: SMED Implementation, Step -2), one of the most important deliverable is, identification of those internal work elements that can be converted to external work element with a little or small change in the process. Here in step - 3 of SMED implementation, the current changeover process is carefully examined and re examined time to time and repeatedly by the project execution team, with a definite intent of converting as many internal work element as possible.
For each of the work element listed based upon the video analysis, the project team must analyse following factors -
1. If there is any way to make this internal element (under consideration), external
2. What changes are required to be made in the process and equipment to make the internal element (under consideration), external
3. How much cost is involved in the process of conversion of internal element (under consideration), to external work element.
Based upon the evaluation conducted by the project execution team, prioritization is done, so that most promising work elements are acted on first. The process of prioritization comes down to cost versus benefit realization analysis, for each of the identified work elements as detailed below :
Once the analysis is done priority matrix is prepared keeping the highest priority work elements in chronology to be taken up for execution.
Some commonly used techniques that can be used to convert internal work elements to external are -
1. Advance preparation technique: - e.g. - preheating of dies in advance to have a smooth setup/ changeover .
2. Performing pre-adjustments : - Performing pre-adjustments and pre-alignments using replaceable or duplicate jigs.
3. Modularization technique : - Instead of doing fitment during changeover, modularization of tooling setup will reduce time.
4. Auto- cleaning technique : - Auto cleaning of die beds during detachment of dies also helps in reducing cleaning time.
5. Auto clamping : - e.g.- automatic clamping and de-clamping with pneumatic controllers instead of manual clamping and de-clamping process.
Deliverables of Step 3 of SMED Implementation (i.e. "conversion of internal setup activities to external setup activities " ) are detailed as below :-
1. Reduced number of internal work element and there by reduction of setup / changeover time.
2. Additional external elements with improved process of performing (to be performed before and after changeover which will increase the machine or equipment availability).
In my next blog I will detail the step 4 of SMED Implementation ( Link : Step 4 of SMED Implementation).
Wish you happy learning!!
