The angle parameters of the tooth section in a multi-blade rip saw for logs are complex and highly specialized. The correct selection of the angle parameters for the saw blades is crucial in determining the cutting quality. The main angle parameters are the rake angle, clearance angle, and wedge angle.

The rake angle primarily affects the force required to cut through the wood. A larger rake angle results in better cutting sharpness, lighter cutting, and easier material feeding. Generally, when processing softer materials, a larger rake angle is chosen, while a smaller rake angle is preferred for harder materials.

The angle of the saw teeth in a multi-blade circular saw refers to the position of the teeth during cutting. The angle of the saw teeth influences the performance of the cutting process. The most significant angles are the rake angle (γ), clearance angle (α), and wedge angle (β). The rake angle (γ) is the angle at which the tooth enters the material. A larger rake angle in a multi-blade circular saw results in faster and lighter cutting. The rake angle is typically between 10-15 degrees. The clearance angle (α) is the angle between the tooth and the already processed surface. Its purpose is to prevent friction between the tooth and the surface, with a larger clearance angle resulting in less friction and a smoother finish. For carbide-tipped saw blades, the clearance angle is generally set at 15 degrees. The wedge angle (β) is derived from the rake angle and clearance angle. However, the wedge angle should not be too small, as it affects the strength, heat dissipation, and durability of the saw teeth. The sum of the rake angle (γ), clearance angle (α), and wedge angle (β) is equal to 90 degrees.

Please note that these angle parameters are critical for achieving optimal cutting performance and should be carefully considered during the selection and design of the saw blades.
