    Saw blade with profiled cuts
    The present invention relates to the field of material removal tools, and in particular saw blades having notches spaced along their periphery, these notches being dimensioned and profiled to form signs corresponding to one aspect of the tool.
    Common material removal tools include cutting tools and abrasives such as saw blades, abrasive saw blades and coring tools that are widely used on conventional mechanical saws and grinding machines. These tools are often circular and configured to be mounted centrally on a machine shaft and rotate around it during use. Other such tools, such as saw blades and the like, are configured to be driven around a pair of pulleys. All of these tools tend to be configured for unidirectional material removal movement relative to a workpiece.
    These tools often have nicks or indentations in the form of peripheral (ie devoid) indentations to perform functions such as removing debris (eg chips), cooling or relieving efforts in use. Notches / voids are also used on grinding wheels or sanding wheels to provide visual access to the workpiece being used, as disclosed in U.S. Patent Application Serial No. 09 / 769,941 to Conley et al. , filed March 2, 2001 and titled Abrasive Wheels With WorkpieceVision Feature.
    The unidirectional nature of many of these tools generally requires proper installation on the machine. The necessary directional orientation is often not easily identifiable for occasional users or even experienced by a simple visual inspection of the tool itself. This is why the correct directional orientation is often printed, painted or otherwise marked directly on the screen. tool, to facilitate its installation. Additional markings, including the tag, logo, or other items indicating the origin, are also often affixed directly to the tool in a similar manner. Unfortunately, however, cumbers are often worn or otherwise removed during the use of the tool, which complicates the identification of the orientation and / or origin of the tool. This may lead to an incorrect installation in the .cas where the tool is disassembled from the machine, and may cause a reduction in new commands if the origin of the tool can not be correctly identified.
    This is why a need exists for a cut / abrasive tool that overcomes the disadvantages mentioned above.
    One aspect of the invention comprises a circular diamond abrasive blade comprising a circular metal body having a substantiallycentral opening through which the saw blade can be mounted on a rotary drive shaft. A series of notches are spaced along a periphery of the body, and a series of notches are spaced between the wells. The cuts extend radially inwardly from the periphery of the body, and are dimensioned and profiled in the form of signs. Cessories may include letters, numbers, graphic shapes, and / or combinations of such elements.
    Another aspect of the invention includes a tool configured to be driven in a longitudinal direction to remove material from a workpiece. The tool includes a body that can be mounted on a drive mechanism and a series of spaced knives along a periphery of the body. At least one score is located between the knives, this notch extending inwardly from the periphery. This notch is dimensioned and profiled to form signs such as letters, numbers, graphic shapes and / or combinations of such elements.
    Another aspect of the invention includes a method for marking a diamond-shaped diamond abrasive cutting tool. This method comprises cutting a series of symbols, such as letters, numbers, graphical forms and / or combinations of such elements, into the metal core to mark the tool and relieve stress along a perimeter of the core. metal during the use of the tool.
    In yet another aspect of the invention, a method is provided for making a circular cutter tool having permanent signs thereon.The method includes providing a substantially circular body having a central opening through which the body can be mounted on an arbred rotary drive, and the provision of knives along a periphery of the body. The method includesproviding at least one notch on the body, extending from the periphery to the aperture, and configuring the selected notch or shaped cutouts in a group composed of alphanumeric and graphic symbols.
    These and other features and advantages of the invention will become more apparent upon reading the following detailed description of various aspects of the invention given in conjunction with the accompanying drawings, in which: FIG. IA shows a plan view of an embodiment of a material removal tool according to the invention, with optional aspects of it being shown in dashed lines; FIG. IB shows an enlarged plan view of a portion of the LaFig removal tool. IA; FIG. 2 shows an elevational view of the removal tool of FIG. IA; FIG. 3 shows a plan view of another embodiment of a material removal tool according to the invention; and Figs. 4 to 6 show similar views to that of FIG. 3, still further embodiments of the material removal tool according to the invention.
    Illustrative embodiments of the invention are described in detail hereinafter with reference to the figures of the accompanying drawings. For the sake of clarity, the like elements shown in the accompanying drawings are shown with like reference numerals. and the similar elements shown in various embodiments in the drawings are indicated with similar reference numbers.
    Embodiments of the invention include diamond abrasive cutting tools with a metal core, such as, for example, saw blades of the type commonly used for cutting masonry elements, having notches configured as alphanumeric and / or graphical indicia. These are normally cut in the metal core, but can be created using any suitable metal fabrication process or technique. These nicks may be configured to provide origin information (e.g., brand mark or distribution mark), security information, or a combination of these. For example, the notches may be configured with letters and / or symbols that represent a tool-maker name or a mark, and / or that are asymmetrical so as to be readable when the tool is installed in the proper orientation (eg ) on a particular piece of equipment (eg a power saw).
    Embodiments of the invention thus provide the combined functions of providing signs that do not wear out or are destroyed in the same manner during use, while providing stress relief along the perimeter of the metal core. .
    In the present description, the term "axial", when used in conjunction with a tool (for example a saw blade) described herein, refers to a direction relative to the tool which is essentially parallel to its center of rotation. (Figs IA and 2) in use. The "longitudinal" and / or "cutting" direction of a tool refers to the direction of the material removal movement of the tool relative to the workpiece. For example, if the tool is circular, the longitudinal / cutting direction is orthogonal to the axial direction. The "face" of a tool is a surface of the tool that extends in the cutting direction.
    Various embodiments of the invention will be described with reference to the figures. On theFig. 1 to 2, an embodiment of the invention comprises a cutting tool such as a masonry circular saw blade 10. The blade 10 comprises a metal core 12 having an opening or a central hole 11 by means of which the blade 10 can be mounted fixed to the shaft of a circular saw (not shown) in a conventional manner, for example with a threaded fastener. As shown, the core 12 is substantially circular in shape and may include virtually any material having sufficient specific strength, and preferably a density of about 2.0 to about 8.0 g / cm 3. Examples of suitable materials are steel, aluminum, titanium, bronze, their compounds and alloys and combinations of these elements. Reinforced plastics with sufficient specific strength can also be used to make the core. Generally, desirable materials for the metal core include ANSI 4140 steel and 2024, 6065 and 7178 aluminum alloys.
    A plurality of knives 14 are spaced apart from the periphery of the core between a series of notches 16, 18. As shown, the knives 14 may comprise abrasive segments of the type used on conventional abrasive saw blades. Cessegments have abrasive grains brazed or otherwise fixed to the surface of the core 12. Practically all conventional abrasives can be used, such as, but not limited to, alumina in molten, sintered and / or by solid process. gel, silica, silicon carbide, zirconium alumina, molten alloys or sintered alumina with at least one ceramic oxide selected from the group consisting of MgO, CoO, TiO2> V2O3, Cr2C> 3, cerium oxide, boron suboxide, legrenat and emery. Super-abrasive grains can also be used, such as, but not limited to, diamond and cubic boron nitride (NBC), with or without a metal coating.
    Furthermore, in an optional variant, the blade 10 may be provided with knives 14 'which comprise a series of teeth 15, as shown in dashed lines in FIG. IA. The teeth may in principle be of any size and shape commonly used on saw blades, for example to cut relatively soft materials such as wood, plastic and the like. In another variant, the teeth may be provided with conventional hardened tips (not shown), such as those made of tungsten carbide.
    As shown, the notches 16, 18 extend inwardly from the periphery of the core 12, preferably terminating in an air-like (for example, substantially circular) air (Fig. 1B). It will be appreciated by those skilled in the art that atmospheric air 20 advantageously aids in attenuating stresses which may otherwise tend to generate stress fractures in the core at the base of the notch.
    The notches can be configured as virtually any sign, including alphanumeric characters and / or various graphical elements. For example, in the embodiment shown in FIGS. IA and IB, the notches 18 are configured to form the letter "W".
    As also shown, each notch 16, 18 must not necessarily be configured as a single. On the contrary, the notches configured as designees 18 may be interposed between conventional notches 16, as shown. This intercalated arrangement may be particularly useful in embodiments that employ knives 14 'each having a relatively large number of teeth 15 and notches 16, as described above.
    The cuts 18 are normally cut in the core using conventional cutting or grinding processes. However, the cuts can be made using any suitable manufacturing process, such as molding, stamping or laser machining.
    In Figs. 3, 5 and 6, other embodiments of wheels 10 are shown in the form of holes 110, 310, 410 having notches 118, 318, 418 which are respectively in the form of letters "N", "C" and "V". . Although these figures represent wheels that have notches representing the same letter, disks may be provided with virtually any combination of alphanumeric or other symbols. The same wheel can thus be provided with notchesconfigurées in the form of different letters to be able to form acronyms, abbreviations or words. Decide way, tools 10, 110, etc. can be customized for particular buyers.
    For example, in FIG. 4, a tool 210 made by "Saint-Gobain Abrasives, Inc." can be customized with a repeating pattern of 218,218 ', 218' 's-shaped, "t" and "g" notches. In addition to alphanumeric signs, the notches can be configured as a corporate logo (an example of a company logo that may be appropriate for such use is the NikeCorporation NIKE® SWOOSH® logo in Beaverton, Oregon. ). This form of realization thus provides a mark / indication of indelible origin which can constitute a practical means for asserting the identity of a brand among its customers.
    This embodiment also provides a convenient way to "mark" the tools intended for resale, for example by configuring the notches with signs associated with the customer / reseller. In this way, the reseller can have a range of custom tools to sell to his end customers. This approach, with the marking in principle permanent, can promote brand loyalty within the customer.
    Likewise, as indicated above, while notches 18, 118, and so on. Combining identification with the functional aspects of stress relief and debris / chip removal, another potentialfunctional aspect of these embodiments is increased safety. Because the alphanumeric signs are cut into the nucleus, extending over its entire axial dimension, these signs will be correctly visible and / or readable (ie, vertical and readable from left to right at the top of the alum as shown in FIG. 4) on one side of the blade, while the inverted image (that is, vertical but returned to the top of the blade) would appear on the other side (for example, if the blade is not installed correctly). As noted above, many saw blades are unidirectional, i.e., they are designed to cut a workpiece in one direction. Those skilled in the art will understand that this unidirectional character usually depends on asymmetries in the configuration of the segments as the orientation of the segments. individual abrasive grains and / or their cutting teeth. As a result, use of these blades in the reverse direction can result in inefficient cutting performance and / or reduced safety. To overcome these disadvantages, embodiments of the invention can be made such that the alphanumeric signs are properly visible on the side of the threaded fastener of a given mechanical saw, as shown in FIG. 4, when properly installed. These embodiments thus provide an easily distinguishable visible indication that the blade 18, 118, and so on. is correctly installed or not. In addition, since this directional information is provided independently of conventional painted or other markings on the face of the core 12, the quality of such visual indication can not fade, defile or otherwise degrade during use. .
    Although the invention has been described with respect to circular saw blades, the skilled person will recognize that virtually any type of cutting or grinding tool of this type having cuts can be used without betraying the spirit or leaving the machine. framework of the invention. For example, otherwise conventional slotted saw blades may be provided with the notch configurations disclosed herein. In addition, non-abrasive circular saw blades of the type commonly used to cut wood, plastic or other relatively soft materials may incorporate the cuts described herein. In addition, although the tools described herein are cutting tools or abrasive cutting tools, the skilled person will assume that cuts configured as described above can be applied to other types of material removal tools such as segmented diamond abrasive wheels with conventional steel core without betraying the spirit or going outside the scope of the invention.
    In addition, although the embodiments described herein disclose notches in designated form, these signs may be placed elsewhere on the tool, for example within the periphery of the tool, without betraying the spirit or going beyond the scope of the tool. 'invention.
    In the above description, the invention has been described with reference to specific examples of embodiments thereof. It is evident that various changes and modifications may be made without betraying the spirit or departing from the larger scope of the invention as set forth in the claims which follow. The description and drawings should therefore be considered in an illustrative rather than restrictive sense.
    Having thus described the invention, the claims are as follows:
