In manufacturing, there is often unavoidable waste that happens during the production processes. This is especially true when factories are producing items in large quantities or with complex technology. When material or resources are wasted in production, it is known as “scrap” or “cutting allowance.”
Scrap or cutting allowance occurs during the cutting or machining of raw material into the final product. When cutting material, some of it may be lost due to imperfect cuts, chipping, or just by the nature of what’s being cut. The amount of waste produced depends on a number of factors such as material type, tooling and machining methods, and cutting speeds.
In order to reduce scrap or cutting allowance, production engineers must take a number of precautions. The most common method is to create a “tool path” on the computer-controlled machine. This path is an exact pattern to be followed by the cutting tool. By following a specific path outlined by a computer input, the engineer can reduce the amount of waste produced.
Another means of limiting scrap allowance is to use special cutting tools such as oil-based drills, milling cutters, and automatic cutoff saws. Each of these tools is designed to cut more efficiently at higher speeds, reducing the amount of material lost in the cutting process.
In addition to these specialty tools, manufacturers can also reduce scrap allowance by making sure all their cutting tools are kept sharp and in good shape. If a tool is not kept sharp and well-regulated, the result may be an inaccurate cut, leaving more waste than necessary.
Finally, planners must also factor scrap allowance into their production plans. This will allow them to accurately determine how much material to order and how much to expect as waste. Adding a buffer of scrap allowance to orders will ensure that all the materials are available for the production process without having to stop and wait for more materials, reducing delays and the potential for over-ordering.
In conclusion, limiting scrap allowance in manufacturing processes can be accomplished through the use of modern technologies and proper tool maintenance. It is a task that requires a team approach, with the input of all involved in the design, engineering and production practices necessary to ensure success. By taking the proper steps, a business can achieve efficiency in its manufacturing process and effectively control costs.
