Abstract

Systems and methods for milling saw blade tooth profiles and saw blades with milled tooth profiles are disclosed herein. The systems include blade milling systems that include a milling head, a blade support structure, a blade advance structure, and a control system. The methods include supporting a saw blade, advancing the saw blade, and machining a finished tooth profile in a working portion of the saw blade with an end mill. In some embodiments, the machining may include operatively translating the end mill relative to the saw blade with a milling head and within a plane that is at least substantially perpendicular to an end mill rotational axis. In some embodiments, the machining may include dry-machining the finished tooth profile in the working portion of the saw blade in a single pass. The saw blades include a plurality of teeth and may include at least one relief region.

Claims21

Dependent claims

A blade milling system for machining tooth profiles in a saw blade, the blade milling system comprising:

a milling head configured to rotate an end mill about an end mill rotational axis and to operatively translate the end mill within an end mill translation plane that is at least substantially perpendicular to the end mill rotational axis;
a blade support structure configured to operatively support the saw blade, relative to the milling head, such that a working portion of the saw blade extends within the end mill translation plane;
a blade advance structure configured to selectively and progressively advance the saw blade, relative to the milling head, to selectively define the working portion of the saw blade;
and
a control system programmed to:
(i) control operation of the blade advance structure to operatively position the saw blade, relative to the milling head, such that a target portion of the saw blade defines the working portion of the saw blade;
and
(ii) control operation of the milling head to operatively translate the milling head such that the end mill translates within the end mill translation plane and machines the working portion of the saw blade to define a finished tooth profile within the working portion of the saw blade.

5 more elements

A method of machining a saw blade tooth profile of a saw blade with a blade milling system, the method comprising:

supporting the saw blade, via a blade support structure, such that a side of the saw blade extends at least substantially perpendicular to an end mill rotational axis of an end mill;
advancing the saw blade, via a blade advance structure and within the blade support structure, such that a target portion of the saw blade defines a working portion of the saw blade;
and
machining a finished tooth profile in the working portion of the saw blade, with the end mill, by operatively translating the end mill relative to the saw blade with a milling head and within a plane that is at least substantially perpendicular to the end mill rotational axis.
