Unit 2: Speed and Feed – Manufacturing Processes 4-5
1. Cutting speed is defined as the speed (usually in feet per minute) of a tool when it is cutting the work. 2. Feed rate is defined as tool's distance travelled during one spindle revolution. 3. Feed rate and cutting speed determine the rate of material removal, power requirements, and surface finish. 4.

Roll pass design in continuous bar mills
Roll pass design in continuous bar mills 1. African Foundries Ltd. Lagos, Nigeria Presented by Rahul Kishore 2. Basics of Rolling A rolling mill consist of several, at least two rolls cylindrical or nearly cylindrical bodies which are termed as "roll" and which rest in bearings at their ends. The normal and average center distance from the center of one roll to the center of o
Roll Torque - an overview | ScienceDirect Topics
The speed of the rolling mill is set at 10 rpm, giving a roll surface velocity of 70.69 mm/s. It was found necessary to use guides for the bars, both at entry and exit, in order to minimize sideways bending. The parameters monitored during the experiments include the temperature, roll force and torque.

theory about mill critical speed
critical, a variable speed drive is recommended. This permits the operator to control his mill speed to suit. Most mills rotate at 60 to 65 percent of critical speed (Nc). This formulation is for wet milling where as dry milling needs to be adjusted by 2 to 5 RPM faster. These speeds hold true for any media regardless of shape for density. Read ...
