Formula for Face Milling MITSUBISHI MATERIALS

(3.14):Pi. n (min-1):Main Axis Spindle Speed. vc (m/min):Cutting Speed. Problem. What is the cutting speed when main axis spindle speed is 350min -1 and the cutter diameter is ø125 ? Answer. Substitute =3.14, DC=125, n=350 into the formula. vc= Milling Speed and Feed Calculator - CustomPart.NetMilling operations remove material by feeding a workpiece into a rotating cutting tool with sharp teeth, such as an end mill or face mill. Calculations use the desired tool diameter, number of teeth, cutting speed, and cutting feed, which should be chosen based on the specific cutting conditions, including the workpiece material and tool material. Speeds and Feeds charts for reaming, drilling, milling Milling Speeds and Feeds. Counterboring Speeds and Feeds. Keyseat Cutter Speeds and Feeds. Feeds and speeds are starting recommendations only. Factors such as machine, fixture and tooling rigidity, horsepower available, coolant application and others will affect the performance significantly.

ASTM A36 steel plate thickness tolerance steel plate,ASTM

ASTM A36 steel plate is the most purchased hot rolled steel plate in the world and the least expensive of the commercial carbon steels. The heat ability reates very good welding properties, and the 36 ksi yield strength makes ASTM A36 steel plate acceptable for most applications. A36 is considered a mild steel due to its relatively moderate hardness.
