There are a number of considerations for CNC milling of molds in mold making, including:

 

  1. Material selection: The type of material used for the mold will depend on the type of parts to be produced, the production volume, and the desired surface finish. Common mold materials include aluminum, steel, and tool steel.
  2. Mold design: The mold design must take into account the geometry of the parts to be produced, as well as the machining capabilities of the CNC milling machine. Factors such as draft angles, parting lines, and cooling channels must be considered.
  3. CAM programming: The CAM programmer must generate toolpaths that will machine the mold to the desired tolerances and surface finish. This can be a complex task, especially for complex mold designs.
  4. Machine selection: The right CNC milling machine must be selected for the job. Factors such as the size and complexity of the mold, the desired accuracy and surface finish, and the budget must be considered.
  5. Tooling selection: The right cutting tools must be selected for the job. Factors such as the material of the mold, the desired machining speed and feed rate, and the budget must be considered.
