cement mill operations in four ways: • More consistent quality (grade). The continual monitoring of the mill loading and the adjustment of the feed and separator results in reduced variations in cement grade. This has the added benefit of a more consistent product quality. The control strategy is designed to respond to disturbances in the

Face mills are tools with a large diameter that are used to cut a wide shallow path for facing operations. Facing is used for machining a large flat area, typically the top of the part in preparation for other milling operations. A face mill is a solid body that holds multiple carbide inserts that can be replaced as they wear out.

The milling operation undertaken in this study uses a ball-nose end mill where the cutting action can take place across the whole surface of the tool. This is a versatile option because the end-mill can be used to cut horizontal surfaces using the end of the tool, vertical surfaces using the end, or side of the tool and can be used for drilling.
