Setup Reduction Module

  • The benefits of quick changeover

    • Meet customer needs

    • CIPP Buyouts (more time for output)

    • Smaller lot sizes

    • Reduced inventory

    • Reduced cost

    • On time delivery

    • Production smoothing

    • Waste elimination

    • Higher quality

    • Increase cash flow

    • Flexibility in scheduling

    • Reduce lead time

    • Increase profitability


Definition of setup time
Definition of Setup Time

  • The amount of time taken to change a machine from the last part of a production lot to the first good part of the next production lot.

  • Including gauging and fine tuning

  • Clock time, not labor time.


Typical setup process
Typical Setup Process

  • Gathering necessary items 25%

  • Exchanging parts 10%

  • Positioning parts 20%

  • Making adjustments 45%

    The biggest opportunity for improvement is in reducing the look time for gathering items and eliminating the need to make adjustments.


Setup reduction terminology
Setup Reduction Terminology

  • Internal Setup

    Work that must be done while the machine is stopped

  • External Setup

    Work that can be done while the machine is running

  • Equipment List

    List of all tools, gages, fixtures, etc. necessary to complete the setup

  • Intermediate Jigs

    Plates, spacers, or frames that eliminate the need to make major changes during the setup

  • SMED

    Single minute exchange of dies-----the goal of all setup reduction projects

Setup Reduction

  • Step 1

    Separate the work that must be done while the machine is stopped (internal setup) from the work that can be done while the machine is running (external setup).

    Create a list of all setup activities and label whether they are internal or external.

    Example:

    Move material into work area E

    Loosen 6 cap screws I

    Remove chuck jaws I

    Remove work stops I

    Change inserts I

    Get part prints E

  • Step 2

    Reduce internal setup by doing more work externally. Determine the baseline time necessary to complete each setup element. Next determine the true function and purpose of each internal setup element and brainstorm ways to do them externally or eliminate.

    Prepare dies, fixtures, and gages outside the machine environment while the old parts are still being machined. Necessary tools should be gathered and laid out in proper sequence of use while the machine is still running old parts. Use setup carts when appropriate.

    Minimize the number of adjustments by standardizing, using dowel pins, and precision locators etc. Duplicate tooling and equipment can be pre-adjusted while the old parts are running.

  • Step 3

    Streamline all internal and external elements that have been recognized as still necessary.

    Make sure that the setup elements are being done in the most advantageous order and means possible. Simplify or eliminate the need for adjustments and tweaking by developing gadgets, set blocks. Use quick change tooling such as chuck jaws, commonize nuts, bolts, and hardware.

    Use a setup team approach if necessary to reduce the time the machine must be down during the setup.

    Involve many disciplines such as toolmakers, processors, operators, quality, and IE’s

  • Step 4

    Fine tune all elements of the setup by training the operators and timing the new setup process. Again look for ways to reduce the time of the longest elements.

    Retime and observe until the operator has the new process nailed.

    “Operating Room” analogy

    Once the new setup procedure is defined create a SOP (Standard Operating Procedure) that is laminated and posted at the machine for use by all operators.


Key activities
Key Activities

  • Set an improvement target

  • Observe the setup as is

  • Brainstorm improvements

  • Create action item list

  • Prioritize implementation

  • Assign Tasks to team members

  • Develop new procedure

  • Perform & time new procedure

  • Train all operators

  • Repeat the setup---practice and retime until all operators are efficient at the new procedure

  • Create SOP, laminate and post


Setup reduction techniques
Setup Reduction Techniques

  • Use color coded equipment

  • Commonize components

  • Commonize wrenches

  • Use air or cordless tools

  • Use hydraulic or air clamping

  • Use digital pictures to document SOP

  • Use precision locators

  • Die carts

  • Shadow boards

  • Organize and label all equipment

  • Use a video camera

  • Use PERT to define the critical path

  • Eliminate the setup altogether by using dedicated machines if possible
