• The type of milling machine most commonly found in student shops is a vertical spindle machine with a swiveling head. Although there are several other types of milling machines, shown is the vertical milling machine. • A milling machine removes metal by rotating a multi-toothed cutter that is fed into the moving workpiece.
The stability lobes diagrams represent the boundary between stable and unstable cutting conditions. In milling, for each value of the radial depth of cut, there is a diagram that indicates what the limiting depth of cut at every spindle speed is. The lobe shape of the boundary is what gives them their name.
UP Milling is known as the Conventional Milling process. Whereas, Down Milling is known as the Climb Milling process. The cutting forces act upward in the UP Milling as you can see in the diagram. Here the cutting forces act opposite to the up milling or you can say downward. The UP Milling process is used for rough purposes.

Straddle milling. In straddle milling, two or more parallel vertical surfaces are machined at a single cut, which is accomplished by mounting two milling cutters on the same arbor, set apart at the exact width of the workpiece. The two sides of the workpiece are machined at the same time with the dimensions being exactly and precisely controlled.
One such process is end milling. End milling primarily differs from other milling processes due to the type of tooling that is used for abrading a given material. 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.
Specific designations of an alloy are described by the amounts and chemical symbols of the alloying elements. For erample, a copper-nickel alloy might be described as capper-nickel, 70 Cu-30 Ni. The 70 Cu represents the percentage of copper and the 50 Si represents the percentage of nickel. 15 Common alloying elements symbols are as follows ...

Straddle Milling. When two or more parallel vertical surfaces are machined at a single cut, the operation is called straddle milling. Straddle milling is accomplished by mounting two side milling cutters on the same arbor, set apart so that they straddle the workpiece. The diagram below illustrates a typical example of straddle milling.
Periphery Mill cutter can only be used for the Horizontal mill machine. 3. Side Milling Cutter: Side Mill cutter is a type of cutter in which the cutting teeth are present on the periphery and also at the face or end. This cutter is mostly used in straddle …

milling cutter has teeth on both sides and on the periphery. When teeth are added to one side only, the cutter is called a half-side milling cutter and is identified as being either a right-hand or left-hand cutter. Side milling cutters are generally used for slotting and straddle milling. Interlocking tooth side milling cutters and staggered tooth
Straddle milling can be used in cutting spline, or squares and hexagons on the end of a cylindrical part. Straddle milling uses sharp milling cutters on either side, it is possible to machine the pieces on opposite sides to parallel in a cut. The indexing head will be utilized to rotate the piece after each cut. Straddle Milling Diagram.
