General Hints on Milling
Milling involves generating machined surfaces by removing material from the workpiece using a milling cutter. The process is characterized by each cutter tooth removing a portion of the stock in the form of small chips.

Types of Milling Cutters
1. Peripheral Milling: The cutter's axis is parallel to the workpiece surface. Cutters may have straight or helical teeth.
2. Face Milling: The cutter is mounted perpendicular to the workpiece surface, with cutting edges on the periphery and face.
3. End Milling: The cutter rotates on an axis vertical to the workpiece and can be tilted for tapered surfaces.

Applications for End Mills
Different applications have varying Material Removal Rates (MRR), which increase with the cutter's engagement section on the workpiece. The Dormer Catalogue uses icons to indicate different applications.

Troubleshooting When Milling
1. Breakage: Decrease feed per tooth if stock removal is too high. Slow down feed if it's too fast.
2. Wear: Use a shorter end mill if flute length is too long. Check the Catalogue/Selector for the correct tool and cutting parameters.
3. Chipping: Reduce feed rate if it's too high. Reduce RPM to prevent chattering.
