Radius of corner is a crucial factor affecting the processability of precision deburring parts. Radii of corners in machined parts not only affect the appearance of parts, but also the processability of them. The smaller the corner radius of a part, the higher its tolerance is, and the better its precision is. Smaller corner radius makes it easier to deburr the part. On the contrary, larger corner radii can require more time and force to clean up the parts, increasing both the process time as well as cost of the manufacturing process.
The first factor that affects the processability of machined parts with small corner radius is the cutting tool geometry. Smaller corner radius requires the cutting tool to have a small tip or edge radius. If the cutting tool has a larger radius than the corner radius of the part, the part will experience a larger radial cutting force and possibly additional vibration, which may influence its processability. The radius of the cutting tool should always be more conservative than the radius of the part to ensure processability.
Second, the corner radius of a part may also be affected by the material used. Certain materials are known to be harder to deburr, such as stainless steel and heat-treated steels. Harder materials with small corner radius may require higher forces and additional machining steps to clean up the edges during the deburring process.
Furthermore, the processability of a part with small corner radius is also affected by the cutting speed. When the cutting speed of a part is too high, the cutting tool may experience a higher cutting force and have more difficulty controlling the corner radius. Additionally, the cutting heat generated by a high cutting speed can also increase, which may damage the part and make it more difficult to deburr.
Overall, the corner radius is a key factor that affects the processability of precision parts. Smaller corner radius requires higher tolerances, precision cutting tools, accurate cutting speed and careful material selection. When these factors are met, the part will experience minimal forces and vibration, ensuring a successful deburring process.
