When you call the millis () function, it returns the current value of the timer/counter in milliseconds (hence the millis () function name). To state it another way, the value that is returned by the function millis () is the amount of time that has passed since the Arduino board was powered up. Let's review some basic Arduino function jargon.

What is End Milling? - CGS Tool | End Mills | Solid ...
Unlike cutters and drill bits, end mills have cutting teeth on the sides and end of the mill. Additionally, the milling applications for the end mill are unique. End mills are typically used in applications requiring profile milling, tracer milling, shape milling, face milling and plunging. For non-conventional or unique applications, CGS Tools ...
The Anatomy of an End Mill - In The Loupe
The overall reach of an end mill, or length below shank (LBS), is a dimension that describes the necked length of reached tools. It is measured from the start of the necked portion to the bottom of the cutting end of the tool. The neck relief allows space for chip evacuation and prevents the shank from rubbing in deep- pocket milling applications.
Milling (machining) - Wikipedia
A mill drill also typically raises and lowers the entire head, including motor, often on a dovetailed (sometimes round with rack and pinion) vertical column. A mill drill also has a large quill that is generally locked during milling operations and released to facilitate drilling functions.
Introduction to Milling Tools and Their Application
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.
