This application relates to clamping of materials during cutting. More specifically, it relates to cutting protection guides for cutting tools.
When a saw such as a table top saw, a chop saw, miter saw, etc. is used to cut a material, such as wood, metal, plastic, cutting protection guides including clamps are used to prevent injuries to a person cutting the materials.
Cutting protection guides keep material pieces square to a cutting blade on a saw for accuracy, and allows the use of stops for repeat cuts and align the material to keep it straight while being cut. Cutting protection guides provide measure of safety for a user of a cutting saw.
There are several problems associated with cutting protection guides used for cutting saws. One problem is that many cutting protection guides are handheld by a user of a cutting saw and require a user of the cutting saw to push a material being cut past the cutting blade.
Another problem is this most cutting protection guides are not useable for cutting saws to hold a very small piece of material (e.g., about 1 or 2 inches or less) of material being cut.
Another problem is this most cutting protection guides are not useable for cutting saws to hold a very small piece of material including a large width, height or thickness of material being cut.
Another problem is that most cutting protection guides are not adjustable to apply different types of downward pressure.
Another problem is that most cutting protection guides are not adjustable in a vertical, horizontal, or on a desired arc, to hold a piece of small material to cut the material at desired angles.
Another problem is that most cutting protection guides are static and not dynamically movable on the cutting saw.
Another problem is that most cutting protection guides are not dynamically adjustable in both a vertical and a horizontal position on the cutting saws.
Another problem is that most cutting protection guides are not designed to hold a piece of material at various angles so a material (e.g., a crown molding material) that needs to be cut a very specific angle (e.g., for a corner of a room, etc.) can be cut safely.
Another problem is that most cutting protective guides are not easily adjustable to allow easy advancement of a piece of material being cut.
Another problem is that most cutting protective guides do not provide multiple different surfaces at multiple different angles to hold a piece of material being cut.
Another problem is that most cutting protective guides do not absorb vibrational forces and torquing forces from the cutting blade of the cutting saw. Such forces are generated when a small piece of material is to be cut and often cause kickback to move the material resulting in a piece of material hard to hold and often leading to an imprecise cut or cut at an improper angle.
There have been several attempts to solve some of the problems associated cutting protection guides.
For example, U.S. Pat. No. 11,383,336, that issued to Suhling teaches “A reversible flip-away work-stop for strut systems. The reversible flip-way work stop includes a first component allowing a work stop positioning plate to pivot in a semi-circular motion allowing the work stop positioning plate to be moved and immediately configured in a right-handed configuration or a left-handed configuration without manual disassembly and reassembly in a strut in a strut system. A second component allowing the work stop positioning plate to be micro-adjusted to measurements including thousands of an inch for precisely measuring a material to be cut. A third component includes a pre-determined length to exactly match an alignment of a front face of the work stop positioning plate allowing a measurement to be read on a measuring component in the strut on the strut system without obstruction. The third component also including a pre-determined width and shape matching a width and a shape of a measuring component in the strut on the strut system allowing easy movement of the reversible flip-away work stop within the strut in the strut system and providing the ability to add a custom measuring component to the strut system.”
U.S. Pat. No. 10,766,109, that issued to Suhling teaches “The invention allows for alignment perpendicular to a track engaged by a securing nut. An opposing tooth key type aligner has two functions: keeps the second track perpendicular to the first track and allows the securing nut to always be correctly oriented to engage with the track. A bolt clamps the securing nut to the track to lock the position of the invention. A second axis perpendicular to the lower track is created with a second track. A bolt connected to a coupler nut engages with the middle track to create a third axis perpendicular to both previous axes. A washer provides a neutral bearing surface between the coupler nut and second track. An elevation bolt sets the vertical position of the object to be mounted. A bolt can be used to fasten an object to the end of the elevation bolt.”
U.S. Pat. No. 10,836,066, that issued to Suhling teaches “A Zero Clearance Fence that gives precision to chop saw fences. The invention consists of two flat surfaces and mounting devices. The flat surfaces are beveled at one edge of both surfaces. The beveled edge allows a tape measure to be hooked on at any desired miter angle. The invention mounts onto the original chop saw fences so that they are able to slide towards and away from the saw blade. The ability to slide allows the fences to always be right next to the saw blade at any miter angle cut for precision in the cut measurements. The mounting apertures can be located anywhere to allow the Zero Clearance Fence to fit on any chop saw.”
U.S. Pat. No. 9,682,454, that issued to Suhling teaches “An in-line indexing mechanism as part of a work-stop system which employs a lead screw to alter the relative distance between a work-stop plate and a swing arm—as well as alignment pins and springs to maintain contact and rigidity between this work-stop plate and swing arm—in order to precisely alter the parameters of a workpiece plane. In particular, the indexing mechanism of the preferred embodiment resides within the extension of an arm, and is located, by default, within the workpiece plane; the act of indexing therefore exerts force upon a workpiece along a coincident axis within said workpiece plane. Additionally, the indexing mechanism may be removed from the workpiece plane, by way of axially rotating the arm, without abandoning the original workpiece parameter and adjustment values.”
U.S. Pat. No. 9,545,734, that issued to Suhling teaches “A clamp that is meant to act as a coordinate locator for any number of power tools, but most specifically for use with the Biesemeyer T-style table saw fences. The assembly is comprised of a C-frame which offers the ability to enact a clamping action and the ability to enact an indexing action. The design of the assembly allows not only for the clamping of an imprecise reference point along a table saw fence, but also the fine adjustment of indexing a screw against the table saw fence.”
However, these solutions still do not solve all of the problems associated with cutting protection guides used for cutting saws. Thus, it is desirable to solve some of the problems associated with cutting protection guides used for cutting saws.
In accordance with preferred embodiments of the present invention, some of the problems associated with clamping materials during cutting are overcome. A cutting protection guide for cutting tools is presented.
Cutting protection guide for cutting tools. The Cutting protection guide includes different clamping components providing plural adjustable clamping pressures at plural different vertical and horizontal and arc curve position locations for a clamping point to clamp down and securely hold a piece of material being cut on a cutting saw. The cutting protection guide allows very small pieces (e.g., about 1 to 2 inches, or less, etc.) of materials (e.g., wood, metal, plastic, etc.) to be safely cut without endangering a safety of a user using the cutting saw.

“Manufacturing” includes the process of making items from raw materials. “Machining” includes various processes in which a piece of raw material is cut into a desired final shape and size by a controlled material-removal process.
A “3D printer” includes 3D printing or “Additive manufacturing.” 3D printing is a process of making a three-dimensional solid object of virtually any shape from a digital model. 3D printing is achieved using an “additive process,” where successive layers of material (e.g., metal, plastic, etc.) are laid down in different shapes. 3D printing is also considered distinct from traditional manufacturing and/or machining techniques, which mostly rely on the removal of material by methods such as cutting or drilling and are “subtractive” processes.
“Extrusion” is a manufacturing process where a material such as aluminum, etc. is pushed and/or drawn through a die to create long objects of a fixed cross-section. Hollow sections are usually extruded by placing a pin or mandrel in the die. Extrusion may be continuous (e.g., producing indefinitely long material) or semi-continuous (e.g., repeatedly producing many shorter pieces). Some extruded materials are hot drawn and others may be cold drawn.
The feedstock may be forced through the die by various methods: by an auger, which can be single or twin screw, powered by an electric motor; by a ram, driven by hydraulic pressure, oil pressure or in other specialized processes such as rollers inside a perforated drum for the production of many simultaneous streams of material. “Pultruson” is a manufacturing process for producing continuous lengths of materials. Pultruson raw materials include metals such as aluminum, etc. or a liquid resin mixture (e.g., containing resin, fillers and specialized additives) and reinforcing fibers (e.g., fiberglass, composite materials, etc.). The process involves pulling these raw materials (rather than pushing as is the case in extrusion) through a heated steel forming die using a continuous pulling device. The reinforcement materials are in continuous forms such as rolls of fiberglass mat or doffs of fiberglass roving. As the reinforcements are saturated with the resin mixture in the resin impregnator and pulled through the die, the gelation (or hardening) of the resin is initiated by the heat from the die and a rigid, cured profile is formed that corresponds to the shape of the die.
There are also protruded laminates. Most pultruded laminates are formed using rovings aligned down the major axis of the part. Various continuous strand mats, fabrics (e.g., braided, woven and knitted), and texturized or bulked rovings are used to obtain strength in the cross axis or transverse direction.
The pultrusion process is normally continuous and highly automated. Reinforcement materials, such as roving, mat or fabrics, are positioned in a specific location using preforming shapers or guides to form a pultrusion. The reinforcements are drawn through a resin bath where the material is thoroughly coated or impregnated with a liquid thermosetting resin. The resin-saturated reinforcements enter a heated metal pultruson die. The dimensions and shape of the die define the finished part being fabricated. Inside the metal die, heat is transferred initiated by precise temperature control to the reinforcements and liquid resin. The heat energy activates the curing or polymerization of the thermoset resin changing it from a liquid to a solid. The solid laminate emerges from the pultruson die to the exact shape of the die cavity. The laminate solidifies when cooled and it is continuously pulled through the pultruson machine and cut to the desired length. The process is driven by a system of caterpillar or tandem pullers located between the die exit and the cut-off mechanism.
A “composite material” is a combination of two materials with different physical and chemical properties. The different physical or chemical properties of the two materials remain separate and distinct at the macroscopic or microscopic scale within the finished structure. Common polymer-based composite materials, include at least two parts, a substrate (e.g., fibers, etc.) and a resin.
When they are combined, they create a material which is specialized material to do a certain job, for instance to become stronger, lighter or resistant to electricity. Composite materials also improve strength and stiffness of the materials. One reason for their use over traditional materials is because they improve the properties of their base materials and are applicable in many situations.
The composite materials include, but are not limited to, “Fiber-reinforced polymers” (FRP) including thermoplastic composites, short fiber thermoplastics, long fiber thermoplastics or long fiber-reinforced thermoplastics. There are numerous thermoset composites, but advanced systems usually incorporate aramid fiber and carbon fiber in an epoxy resin matrix. The composite materials also include carbon/carbon composite materials with carbon fibers and a silicon carbide matrix.
