The process of CNC machining aluminum parts is associated with a number of challenges that might hinder the quality and efficiency when manufacturing such products. However, one major concern is heat conductivity of the material since it may result in thermal deformations and tool wear at high speeds. This is difficult though due to the risk of expansion in dimensions caused by heat. The tendency of aluminum to generate chips that stick onto the tool can also lead to some challenges. Secondly, the high level of precision in chip evacuation and avoiding re-cutting chips might be more difficult. Optimal tool selection, cutting strategies along with coolant management are critical to combating these problems and improving the CNC machining of aluminum parts.
