A CNC optimization problem can be seen as a robotics optimization exercise. Here below some practical tips on how to improve the performance:
> Move fast when not cutting (tool change, approaching the part) and using the best type of move (absolute, incremental) for each operation.
> Run motors with smoothly acceleration and deceleration, this can improve the quality of the process but also it contributes to the lifetime of the wearing parts of the machine such as bearings, motors, spindles, transmission parts
> Get the best trade-off between lifetime of tooling costs (endmills, drills, cutting inserts, better materials such as carbides) and process parameters (speeds, feed rates, drilling peck depths)
> Eliminate unnecessary setups, part handling, tool changes, retract movements
> Machining 3D surfaces in 1-2 pass toolpaths rather than 3D toolpaths
> Custom build optimized fixtures and tools to optimize machine capacities and machine the max. amount of parts at once
> Great Software integration between CAD and CAM. Some examples are:
> CAD: Inventor, CAM: Esprit
> CAD: SolidWorks with Add-in SolidCAM or Mastercam
> CAD and CAM: Siemens NX, Fusion 360, Mastercam
