Machining

Milling Speed and Feed

Determine the spindle speed (RPM) and feed rate (IPM) for a milling operation, as well as the cut time for a given cut length. Milling operations remove material by feeding a

Milling Horsepower

Calculate the horsepower required for a milling operation based on the feed rate and depth of cut, which are used to determine the material removal rate (or metal removal rate).

Milling Step-over Distance

In many milling operations, the cutting tool must step over and make several adjacent cuts to complete machining a feature. As a result, a small cusp of material, called a scallop,

Drilling Speed and Feed

Determine the spindle speed (RPM) and feed rate (IPM) for a drilling operation, as well as the cut time for a given cut length. Drilling operations are those in which a cutting tool

Drilling Horsepower

Calculate the horsepower required for a drilling operation based on the feed rate and tool diameter, which are used to determine the material removal rate (or metal removal rate).

Drill Size Chart

The drill size chart provides a list of standard size drill bits in several measurement systems, including fractional, metric, wire gauge number, and letter. The decimal

Tap Size Chart

The tap size chart provides a list of standard size taps, specifying the diameter and thread spacing, for fractional, metric, and screw sizes. The decimal equivalents of the

Turning Speed and Feed

Determine the spindle speed (RPM) and feed rate (IPM) for a turning operation, as well as the cut time for a given cut length. Turning operations remove material from a rotating

Turning Horsepower

Calculate the horsepower required for a turning operation based on the feed rate, depth of cut, and cut diameter, which will determine the material removal rate (or metal removal

Turning Surface Roughness

Calculate the surface roughness for a turning operation based on the tool nose radius and the cutting feed (IPR). Single-point cutting tools used for finishing operations have a

Sheet Metal

Bend Allowance

The bend allowance and bend deduction are two measures that relate the bent length of a piece of sheet metal to the flat length. The bend allowance describes the length of the

Bending Springback

After a bending operation, residual stresses will cause the sheet metal to spring back slightly. Due to this elastic recovery, it is necessary to over-bend the sheet a precise

V-Bending Force

Calculate the required force to bend a piece of sheet metal using V-bending, a process in which a V-shaped punch presses the sheet into a V-die. The bending force can be

Wipe Bending Force

Calculate the required force to bend a piece of sheet metal using wipe bending, also called edge bending. In this process, the sheet is held between a wipe die and pressure

Deep Drawing Force

Calculate the required force to deep draw a piece of sheet metal based on the drawing ratio, sheet thickness, and the ultimate tensile strength of the material. The drawing
