Milling is the process of machining using rotary cutters to remove material by advancing a cutter into a work piece. This may be done in varying directions on one or several axes, cutter head speeds, and pressures. Milling covers a wide variety of different operations and machines, and works on parts from tiny to large, heavy-duty army-of-machines milling operations. It is one of the most commonly used processes for machining custom parts to precise tolerances.
What are the Different Types of Milling?
What are the Advantages of Milling?
Highly Accurate. Tolerances as low at 0.001″.
Versatile. Multi-axis cutting allows for highly complex geometries.
Short-Run Efficient. Smaller volumes of product often price better.
High Tolerances and Fine Finishes.
What are the Limitations of Milling?
Significant Programming Needed. Depending on the part complexity and contours.
Additional Setups. Parts with features on all sides can require multiple setups and occasionally custom fixtures to hold the workpiece in place as it is cut by the milling tool.
Internal Features Cannot be Machined. If not visible or accessible by the tool.
