## Surface Finish: Calculators, Convertors, and Charts

Surface finish (Also called sometimes surface roughness) is a numeric representation of a surface's "smoothness". There are 3 main ways to acquire the surface roughness value: Mechanical Scan: The most common method is to scan the surface with a needle that records the micro "Hills " and "valleys" along a linear section.

## Chapter 18. Feed Milling Processes

The screw operates at speeds of 100 to 200 rpm and vertically conveys incoming materials from the bottom (generally the intake) end, like a screw conveyor, to the top where they are stered and fall by gravity. This sequence is repeated several times until a blend is attained (usually from 10 to 12 minutes).

## Understanding cutting equations | Cutting Tool Engineering

· The following equation is used to calculate spindle speed: rpm = sfm ÷ diameter ×, where diameter is the cutting tool diameter or the part diameter on a lathe in inches, and is a constant that comes from an algebraic simplification of the more complex formula: rpm = (sfm × 12) ÷ (diameter × π). Because the tool diameter is ...

## Motor Sizing Basics Part 4

When pulleys, belts, gears, sprockets, chains, etc. are used as the transmission mechanism, the dynamic radial load is calculated with the following equation. W = T / y. With a belt conveyor, the motor torque provides the driving force that generates work. This is shown as T, which is the amount of torque in N·m.

Specifying Linear Motion With X, Y, and Z: Specifying G00 or G01 does not cause any motion to happen–they merely tell the controller what type of motion is expected when you finally tell it where to move to. For actual motion you need to specify a destination using the X, Y, and Z words.
