22/07/2016Considerations for Multiple Setups of CNC milling. Often a part will need to be milled from multiple angles. While this can sometimes be handled by 4- or 5-axis milling, on a typical 3-axis machine multiple setups will be required. Each setup costs additional time and money, especially when the volume of parts to be machined isn't very high.
