WHY SET UP REDUCTION
2017-06-19 12:12:53| Anderson Tool and Die
Last week we discussed some of the activities that caused long set up times. Before we begin our discussion about how to reduce set up times, let’s thoroughly understand why we need short set up times. The first benefit is obviously the saving of the “waste” time out of production, which was discussed last week. Since we said we do not get paid for the set up time on the job, this savings is easily understood. The other equally important reason for quick set up is the ability to economically run small quantities of parts. Historically we have wanted to run large quantities of parts so the cost of the set up per part could be low. Customers are no longer willing to accept long waiting times and then take delivery of large quantities of product. They only want to buy, at one time, the amount of product they can consume in a very short period of time. Also, since they do not keep inventory to keep them running, they want quick delivery. This is called “Just In Time” manufacturing. It is the way efficient business works today. Short set up time is the key to economical small lot quantity production. To help explain how critical set up time is to delivery, let’s consider for a moment if set up time could be zero. If set up can be done instantly, then we can make as few parts per order as the customer wants, and then switch over instantly and make other parts for another customer without “wasted machine time during set up” and without concern about the cost of set up. This keeps our customers happy, our “waste” on long set ups low (zero), and keeps our equipment busy making money. In this scenario no one pays the cost for inventory, yet every one keeps their production running efficiently, without wasted down time either waiting for parts or for set up time. The customers are happy, and our business is efficient. Fast set up permits small orders, at low cost, delivered quickly, and the ability to go from one job to the next almost immediately. If there is a secret to success in today’s manufacturing world, short set up times ranks right up there with technological capability as the prime key to success. Even though we may not be able to eliminate set up time completely, as speculated in the above example, we can do many things to minimize set up times. Set up reduction techniques begin next issue.
SET UP TIME
2017-06-19 12:12:53| Anderson Tool and Die
Set up time is the total amount of time it takes to prepare to make the next saleable part, beginning at the time you log off the last job. Set up time includes such activities as the following: · Go to find out what to run next · Find the correct router · Log on to set up per the job number · Clean up from the last job if necessary · Rearrange floor-standing tools from last job · Look for the proper raw materials · Ask others questions about the job or the work center · Take the router to the saw department to get materials cut · Read the Router · Find and talk with management or others for clarification on the job · Look for tooling & tool holders in the tool box · Walk to other tool cabinets to search for tools, as required · Search for those tools in the other cabinet · Negotiate with the person at the other cabinet to borrow tools · Return to your work area · Find the hand tools required to do the set up…walking, searching · Break down and set up the required tooling · Download the program · Determine where the tooling goes in the magazine · Gather floor drill and sander, saw, etc. as required · Go to get a sample piece of raw material, if necessary · Test load the part into the machine · Modify fixtures/jaws as required · Go get raw material if not delivered · Run 1st test piece · Go to QC to get inspection gages and tools as required · Inspect 1st test piece · Take to QC if required, or · Find another person to double check dimensions · Make adjustments to machine as needed to produce a good part · Repeat until achieving good part at router-rated pieces per hour · Make any final finishing adjustments, including cleaning off work cabinet and laying out measuring instruments in logical order · Find QC sheet and fill in dimensions, if necessary · Find and set up packing materials · Find tape gun and tape if required · Find and arrange carts for raw and finished materials · You have now completed the set up functions. You are ready to run production. Log off SET UP and log on to RUN. Nothing you have done up to this point in the job is billable to the customer! (And I probably left out some steps you sometimes have to do to get the job running properly.) We cannot get paid for any of this time. The company (you) have worked for free up to this point on the job . The above scenario illustrates why everyone needs to be concerned how long it takes to set up jobs. A major part of lean manufacturing focuses on minimizing set up time; often called set up reduction. Set up reduction is important in all businesses, but is absolutely critical to success in a job shop. Next week we will begin discussing how to reduce set up time.

Author: Jessica SSubject: Travertine set in concrete for pool deckPosted: 18 Jan 2010 at 3:57pm Originally posted by MitchellI would appreciate some advice on the best way to set travertine in a concrete pool deck. The current advice is to poor the concrete slab with forms for the travertine and then wet set the travertine into the formed areas. The travertine would be sealed after it is set. I have read about issues with the porous nature of travertine and I am not sure if this is the best way. Should drains be placed under the travertine leading to the gravel under the concrete slab? Thanks.Hi , I am a new member of forum. Would a newcomer be warmly welcome here? Good day you guys!!!Edited by findstone - 20 Jan 2010 at 1:52pm
