Controlling Setup Time Variability In The Small Shop
To be as efficient and effective as possible, all set up data should be clearly and concisely documented. One of the biggest mistakes made today is assuming that the person who set up and engineered the process the first time will be there to do it again.
One of the great time drains in contract manufacturing is the unnecessary reinvention of a machine setup that should have already been proven and debugged. When a job is initially quoted, the cost of the setup is taken into account, but with the current setup documentation practices of many small manufacturers, the setup is more often than not repeated the second time with operators and setup people attempting to either remember the way they did it before or diligently trying to interpret a setup note that made sense previously, but has somehow lost its clarity with time.
When a setup is completed, the data needed to replicate the setup later can be quite extensive. To be as efficient and effective as possible, all of the data, from pickups and tooling data to inspection data and general notes, must be clearly and concisely documented. One of the biggest mistakes made today is assuming that the person who set up and engineered the process the first time will be there to do it again. The fact of the matter is, that in this day and age of high turnover, it is quite likely that another person is going to be digging through handwritten notes and spending more time attempting to decipher a setup than if he or she were to do all over again from the beginning.
Ace Manufacturing (Rochester, New York) was facing just this set of problems when it was introduced to a series of applications designed just for the small shop. When the prospect of controlling and managing the setup process for the shop came its way, the first needs outlined were simplicity, “real world” effectiveness and cost effectiveness. Ace considered many different options once it recognized its need to control the setup process, including everything from Microsoft Word templates to high-end document control packages. The problem that Ace came up against again and again was either underkill or overkill with both of these solutions. The Word templates were just too generic for its needs, and the high end document control packages, while excellent for larger companies with IT departments, did too much and did not address the unique needs of the small shop. What the company needed was an application that attacked its problems and did it in a clean no-nonsense fashion.
During its search Ace came upon timeKillers Software from Chadakoin and its setup documentation software. After seeing one system after another that did “everything,” Ace realized that in the end it only had to accomplish certain tasks to get the job done. Adding more abilities beyond what was necessary to the software had only one result and that was to add complication. With the Chaser applications from timeKillers, Ace was able to save considerable time and money with a minimal investment and a small learning curve. “Before Chaser, we were constantly redoing our setups, figuring out tooling, part datums and generally scratching our heads wondering how it was done the last time,” says Eric Johnson, president of Ace. “And don’t even mention when we have had key people leave; too many times the setup data was in their heads and went out the door with them. Now, I believe it is reasonable of me to expect that the next time we run a part, setting it up is going to be a whole lot less complicated than the first time. Since I can’t control my vendors being late or my machines from breaking down, it means that the things in the shop I can control, I must.” With this software, Ace has one more tool to get jobs done. Now, the biggest problem is not the inability to read illegible notes or wondering why no one left a note, it is deciding how best to refine setups and processes, now that the option is available.
“We do anywhere from ten to 25 setups a week,” says Mr. Johnson, “and if I can save even 15 minutes per setup that’s a savings of $7,800 to $19,500 a year (at a $60 shop rate). For a $200 investment with almost no learning curve for my employees, how could I go wrong?” MMS
New geometry-driven quoting technology lets job shops generate estimates in as little as 15 minutes. It enables them to respond faster to RFQs, drastically reduces time wasted on jobs they don’t get, and lets them focus on more profitable work.
Bridging the gap between process engineering and shop floor activities can bring about a "deproliferation" of cutting tools.
