What is Rake Angle in Welding?

Rake angle is the angle between the cutting edge of a shear knife and the plane of the workpiece. It is typically measured in degrees and can range from 0 to 30. Rake angle affects both the cutting action of the knife and the finish of the cut surface. A higher rake angle will result in a more aggressive cut, while a lower rake angle will create a smoother finish.

Rake angle is an important consideration when choosing a shear knife for a particular application. It is also important to keep in mind that the rake angle can be affected by wear on the cutting edge and should be periodically checked and adjusted as needed.

What is the purpose of rake angle?

Rake angle is used to adjust the cutting action of a shear knife. A higher rake angle will result in a more aggressive cut, while a lower rake angle will create a smoother finish.

What is clearance and rake angle?

The term “clearance” is used to describe the angle between the cutting edge of a shear knife and the plane of the workpiece.

Which rake angle is best?

The best rake angle for a particular application will depend on the material being cut and the desired finish.

Negative and positive rake angle

Rake angle is typically measured in degrees and can range from 0 to 30.

How can tool rake angle and clearance angle define?

Tool rake angle is the angle between the cutting edge of a shear knife and the plane of the workpiece. The clearance angle is the angle between the cutting edge of a shear knife and the plane of the workpiece.

Zero rake angle

A zero rake angle is an angle between the cutting edge of a shear knife and the plane of the workpiece that is 0 degrees. This type of rake angle is typically used for applications where a smooth finish is desired.
