Line Cutting Roughness Problem
Line cutting is a manufacturing process used to cut some materials into the desired shape and size. It is widely used in various industries such as sheet metal, glass, and plastic. This process involves the use of power-driven blades to cut through materials. As with any type of machining process, it’s important to achieve a good surface finish. Unfortunately, when it comes to line cutting, large amounts of burr formation and rough surface finish are common problems.
The most common cause of a rough surface finish when line cutting is excessive vibration. The vibration is caused by the feed rate being too fast and/or the depth of cut being too large. This can cause the blade to vibrate excessively and affect the quality of the cut. Another cause of excessive vibration is the cutting tool not being properly secured in the machine. If the cutting tool is not properly secured, its vibration is not dampened and the cut surface will have a rough finish.
If the vibrations are the main problem, the first step is to ensure that the cutting tool is properly secured into the machine. If the cutting tool is not most secure, it will vibrate more and create a rough surface finish. Another way to reduce vibrations is to use a softer cutting material. Softer materials are better at absorbing vibrations than harder materials. Additionally, setting the feed rate and depth of cut appropriately is also important. The faster the feed rate and the greater the depth of cut, the more likely it is for the variations to cause vibration and a rough surface finish.
In some cases, even if the material is softer and the feed rate and depths of cut are set properly, the line cutting process still produces a rough surface finish. In such cases, it may be necessary to use abrasives to produce a smooth finish. Some common abrasives used are silicon carbide and diamond, which are often used in the form of a slurry. A slurry is a suspension of abrasive particles in a liquid, which can be applied to the material during or after the machining process. The slurry then smoothens out the rough surface and produces a better finish.
Line cutting is an extremely versatile and valuable manufacturing process, but the results can be affected by vibrations and burr formation. To minimize the effect of vibrations, it is important to ensure that the cutting tool is properly secured and that the feed rate and depth of cut are set appropriately. In some cases, it may also be necessary to apply abrasives to achieve a good surface finish.
