In manufacturing, knurling is a finishing process used to create any combination of horizontal, vertical or crossing lines on the surface of a workpiece. For example, if a manufacturing company wants to add a diamond-patterned texture to a product — or a component of a product — it may use knurling.
For knurls listed as a Metric Pitch, the pitch on straight knurls is the approximate tooth to tooth distance at the outside diameter of the work part measured in millimeters. For diagonal and diamond wheels, the Metric Pitch is measured perpendicular to the teeth or helix angle.
Beside this, What is TPI in knurling?
TPI Is the number of teeth per inch. Circular Pitch Is the distance between tooth to tooth. Diametral Pitch Is the number of teeth per inch of. diameter. Knurling Specification.
Likewise, How is Knurl pitch calculated?
There are two pitch systems for specifying tooth spacing on a knurl. Circular pitch is based on the distance between the teeth per inch (TPI). It is measured along the wheel from one tooth point to the next. Diametral pitch is based on the number of teeth per inch of the wheel’s diameter.
Also, How is Knurl TPI measured?
For diagonal knurl wheels, the *TPI is measured perpendicular to the teeth or helix angle. The circular pitch measurement in inches, is derived from 1 inch divided by the number of Teeth per Inch with the exception of 14, 21, and 33 TPI.
What is Knurl diameter?
The knurling wheels are made of hardened tool steel and normally have a diameter of 15 – 20 mm. The teeth are similar to small cutting edges of tools.

How is Knurl pitch measured?
Knurl Pitch is simply the number of knurls (teeth) per unit length of measure. … Divide the number of cutting teeth on the wheel by the blank circumference of the wheel in inches to find the number of teeth per inch (TPI). For example, if a wheel with a blank circumference of 6.28 inches has 157 teeth, it has 25 TPI.
What is knurling on a lathe?
Knurling is a manufacturing process, typically conducted on a lathe, whereby a pattern of straight, angled or crossed lines is rolled into the material.
How do you measure the depth of a Knurl?
Divide the number of cutting teeth on the wheel by the blank circumference of the wheel in inches to find the number of teeth per inch (TPI). For example, if a wheel with a blank circumference of 6.28 inches has 157 teeth, it has 25 TPI. Divide 1.000 by the TPI of the knurl to calculate the knurl’s circular pitch.
What does NURL mean?

What is Knurl pitch?
For knurls listed as a Metric Pitch, the pitch on straight knurls is the approximate tooth to tooth distance at the outside diameter of the work part measured in millimeters. For diagonal and diamond wheels, the Metric Pitch is measured perpendicular to the teeth or helix angle.
What is form knurling?
In form knurling, the surface of the workpiece is adapted in a non-cutting process. Cold forming is used to shape the material, which limits its use to materials that are suitable for cold forming. Home.

– Diametral pitch is based on the number of teeth per inch of the wheel’s diameter.
Is knurling a metal cutting operation?
Forcing a knurling tool against the workpiece whilst it rotates in the lathe is the commonest way of knurling. The knurling is actually done by a small wheel that has the necessary pattern cut on it. The tool is really just a holder for the knurling wheel. The metal is not cut but is squashed into shape.
