Intended users

Mechanical Engineers designing something to be CNC milled.

Need you’re trying to provide a solution or support for

Sometimes there is too much to decide on a metal for a CNC project, so it would help to have specific guidelines on the requirements of the project to just output an answer for the most applicable metals.

Constants

  • Budget
  • Length
  • Width
  • Height

Inputs

  • Material (Brinell hardness and cost values)
  • Machining time (size of tool)
  • Design complexity (Number of part flips and number of setups)
  • Strength importance (0 being irrelevant, 1 being important)

Underlying logic of the model you’ll implement

The final value should be a function of the cost, machining time, and strength. This statistic should be used as a design assistant’s recommendation for which design to choose. A basic formula for such could be:

value = 2*cost + partFlips + setups + 1/toolSize + strengthImportance*brinellHardness

Outputs

  • Percent of Budget Used
  • Volume
  • Surface Area
  • Decision Factor (value from equation)
