Metals? While CAD drawings are a vital part of documenting product information, they fail to capture complex bill of materials (BOM) information or show changes made to a design once it moves into production, so relying exclusively on CAD drawings increases the odds of error and makes scrap and rework more likely to occur. As weve noted in this post on knowledge sharing, easier sharing of information and processes can impact line performance and reduce downtown. 5 Things to Consider When Choosing Pull Handles.

The % of kg tells us how serious is the problem. When people cannot find the latest SOPs, they often work from outdated versions, which leads to little mistakes, as well as major quality and manufacturing issues that ultimately require rework or result in scrap. Its easy to overlook the importance of proper documentation when youre busy running a manufacturing business. Note: this graph can also be very effective if we use accumulated 6 months data. Imagine a scenario where a significant engineering changedesigned to improve the productis released without the manufacturing teams knowledge. The organization protects itself this way, making sure the loss is transferred to the customer with a price that gives the desired contribution margin despite the scrap. Material planning, production planning, KPI and lean. 3) Do not allow scrap to be built into the cost structure. So how does that occur? Here are nine suggestions: Mike Lynch, Founder and President of CNC Concepts, notes that most of what causes scrap workpieces can be traced to human error. Not surprisingly, these issues are typically tied to training. Everyone approaches scrap in a different way. If the cost percentage is higher than the quantity (as in the example), we lose more expensive materials which meanswe lose more materials on expensive product batches than on cheaper ones. A couple metal shavings isnt going to place a financial strain on your business. Hazardous waste? Born in the U.S. and raised in Mexico, Elizabeth was introduced to the family business, a scrap metal yard, at an early age. You would be best to describe the company, product(s) and what type of scrap. most of what causes scrap workpieces can be traced to human error. Not surprisingly, these issues are typically tied to training. Manufacturers should consider electronic change management software to help eliminate rework and scrap expenses. . This is more of a dynamic list, which moves beyond the initial list created with the CAD drawings. For example, if we extrude something, then paint and wrap it, we need to give different costs to each step. Of course, its next-to-impossible to avoid all forms of scrap in the manufacturing industry. Cost of Poor Quality (CoPQ) - Scrap element of calculation includes lost margin? You may also decide it is a great idea to invest your time to create re-work and re-process methods, procedures and policies so that your scrap does not entirely go to waste. Besides, at times, large scrap sources reside in unusual places of the supply chain where no-one looks because they are too busy looking at the so-called operating scrap. Or are they introducing errors on the manufacturing line?

Weve blogged about the importance of automating changes on the fly. According to Mark Cheatham, Vice President of Engineering at Strouse, The real challenge is getting the product development team to understand the end goal. The earlier the product development team is involved in the design, the faster they can point out troublesome production elements. The cost perspective allows us to give different prices to scrap at different stages. Incorrect BOM information can result in ordering the wrong partsand if the parts cant be returned or used in other products, they become scrap for the company. , easier sharing of information and processes can impact line performance and reduce downtown. Remember, people do not change, they just behave differently when they are after something of interest to them. In addition to documenting product data, manufacturers can help reduce scrap and rework by carefully and consistently monitoring how products are made. In this case we should first look to improve tools that run more expensive materials. Reducing it can be complicated by your own internal processes, and the nature of the run. All users should evaluate product suitability for each intended application of that product under actual use conditions. Because scrap can occur when a change is implemented at the wrong part of the manufacturing process, it is essential that change information is communicated to all key stakeholdersinternal employees as well as the manufacturers supply chain. That will give a clear view of the problem. We can look at the stages in terms of kg/units if it is relevant to all stages, or in terms of cost. In other words, the in-process measure tells you if the job is getting done or not. Many manufacturing companies view scrap, excess raw material that was not needed during the manufacturing process, as an inevitable part of running their business.

By your continued use of this site you accept such use. Common Quality Assurance Processes and Tools, Quality Manager and Management Related Issues. But to further minimize the risk, manufacturers must also document and optimize the way they manage changes to the manufacturing process. This operational scrap is then broken down into Paretto charts to launch 6-sigma models and so forth. While you may be capturing standard operating procedures (SOPs) and work instructions early on, its important that team members have quick and easy access to the most up-to-date versions of these documents. And the risk of human error occuring in the handling of these parts heightens the chance of nicks, scratches or defects.
