Abstract
Stabilization of a circular saw blade is provided, through use of a blade stabilizer mounted adjacent a workpiece in a fixed relationship to the workpiece and having a stabilizer contact element adapted to bear against the circular saw blade and exert a force against the saw blade in a direction substantially perpendicular to a cutting plane of the saw blade at a point on at least one of the blade faces on the working side of the blade, proximate an axis of motion passing through an axis of rotation of the saw blade and the workpiece in the cutting plane, as the circular saw blade and/or the workpiece move relative to one another along the axis of motion. The axis of motion may be linear or curved. Some embodiments include additional blade stabilizers.
Claims21
An apparatus, comprising:
- a workpiece support arrangement;
- a saw blade arrangement including a circular saw blade having a diameter and being mounted for rotation in a cutting plane about an axis of rotation and movable along a horizontal linear axis of motion of the circular saw blade extending through the axis of rotation perpendicular to the axis of rotation and within the cutting plane for cutting a workpiece carried by the workpiece support arrangement and extending through the cutting plane along a workpiece axis extending through the cutting plane, with the circular saw blade also defining oppositely oriented first and second faces thereof joined by a cutting edge extending around a periphery of the circular saw blade, the circular saw blade further defining a working side thereof extending toward the workpiece axis along the axis of motion of the circular saw blade and a non-working side thereof extending oppositely from the workpiece axis along the axis of motion of the circular saw blade;
- a first blade stabilizer mounted to the workpiece support arrangement adjacent the workpiece axis in a fixed relationship to the workpiece axis and having a stabilizer contact element adapted to bear against the circular saw blade and exert a force against the circular saw blade in a direction substantially perpendicular to the cutting plane at a point on at least one of the circular saw blade faces proximate the axis of motion of the circular saw blade on the working side of the circular saw blade as the axis of rotation of the circular saw blade moves laterally along the axis of motion;
- further comprising, a secondary blade stabilizer mounted opposite the first blade stabilizer substantially along the axis of motion of the circular saw blade in a fixed relationship to the rotational axis of the circular saw blade and having one or more stabilizer contact elements adapted to bear against the circular saw blade and exert a force against the circular saw blade in a direction substantially perpendicular to the cutting plane at a point on at least one of the circular saw blade faces proximate the axis of motion of the circular saw blade on the non-working side of the circular saw blade as the axis of rotation of the circular saw blade moves along the axis of motion of the circular saw blade;
- and
- wherein the first blade stabilizer is linearly movable with the circular saw blade along the axis of motion of the circular saw blade and the second blade stabilizer is not linearly movable with the circular saw blade along the axis of motion.
