Abstract
A sample cutting assembly includes a blade, a base block, an external blade guide, and an internal blade guide. The cutter can be used to conveniently remove samples for material testing to determine serviceability or material condition. Apparatuses and techniques for using the sample cutting assembly are also disclosed.
Claims20
A sample cutter comprising:
- a blade having a cutting edge;
- a base block defining a blade channel having a variable portion of the blade therein, wherein the blade channel includes a pair of blade openings that open at a saw end of the base block such that an arc of the blade extends beyond the base block;
- an internal blade guide configured to engage the blade;
- an external blade guide, the external blade guide with the internal blade guide defining a portion of the blade channel toward the saw end of the base block;
- wherein the internal blade guide and the external blade are configured to engage the blade;
- an internal blade guide extension comprising a free end and a fixed end, wherein the fixed end is directly attached to the internal blade guide and the free end is configured to engage a portion of the blade adjacent to the arc of the blade, wherein the internal blade guide extension is flexible, and wherein the internal blade guide extension is configured to flex based on alignment of the blade channel, a kerf of a workpiece, and the blade;
- and
- a drive assembly supported on the base block, the drive assembly engaging the blade to move during a cutting operation.

A sample cutter comprising:
- a blade having a cutting edge defining a cutting direction;
- a base block enclosing a portion of the blade with a remainder of the blade extending outward of the base block to form an arc, wherein the base block is pivotally mounted;
- an internal blade guide configured to engage the blade;
- and
- an internal blade guide extension comprising a free end and a fixed end, wherein the fixed end is directly attached to the internal blade guide and the free end is configured to engage a portion of the blade adjacent to the arc of the blade, wherein the internal blade guide extension is flexible, and wherein the internal blade guide extension is configured to deflect based on alignment of a blade channel, a kerf of a workpiece, and the blade.
2 more elements
A method, comprising:
- providing a sample cutter, the sample cutter including:
- a blade,
- a base block having a saw end and a drive end,
- a saw pressure device disposed within the base block toward the drive end of the base block,
- an internal blade guide disposed toward the saw end of the base block and configured to engage the blade;
- and
- at least one internal blade guide extension comprising a free end and a fixed end;
- rotating the blade within the base block and internal blade guide, at least an arc of the blade extends beyond the saw end of the base block;
- supporting the blade using the at least one internal blade guide extension, wherein the fixed end is directly attached to the internal blade guide and the free end is configured to engage a portion of the blade adjacent to the arc of the blade, wherein the at least one internal blade guide extension is flexible, and wherein the at least one internal blade guide extension is configured to flex based on alignment of a blade channel, a kerf of a workpiece, and the blade;
- and
- moving at least the portion of the blade extending beyond the saw end of the base block through a sample cutting path including at least a portion of a workpiece.
