A device and system for a rotary boring tool that enables a user to align the tool with respect to a target work surface is disclosed. The alignment system includes a rotating member that is mounted on the rotating portion of a rotary boring tool, and a separate portable stationary member that is designed to reside on the work surface. The rotating member includes a focused light source, such as a laser, that projects a light beam parallel to the direction of the rotary boring tool bit onto the stationary member which reflect the beam and produces a visible pattern on the surface of the stationary member that indicates alignment or misalignment of the rotary boring tool with respect to the work surface.

A drill device includes a drill tip and a drill body having a rear portion. The drill tip includes at least a first clearance surface and the drill body includes at least a first land having a margin. An edge is disposed between the first clearance surface and the margin. A textured area having a plurality of recesses extends along at least a portion of the margin, in the direction of the rear portion of the drill body, from a position of 200 μm from the edge, from a position on the least first clearance surface, or from a position therebetween.

A method for manufacturing a cutting tool according to one embodiment is a method for manufacturing a cutting tool, the cutting tool including a base material and a diamond single crystal material fixed to the base material, the diamond single crystal material having a rake face, a flank face continuous with the rake face, and a cutting edge formed by a ridgeline serving as a boundary between the rake face and the flank face. The method for manufacturing a cutting tool according to one form of the present disclosure includes a flank face irradiation step of applying a laser to the diamond single crystal material along the cutting edge from a side of the flank face. The laser has a pulse width of 1×10.sup.−12 seconds or less and a peak output of less than 1 W in the flank face irradiation step.

The invention relates to a method for creating a press connection arrangement and a clamping connection, the method including a plurality of steps, as well as a press connection arrangement and a clamping connection per se.

A device for ascertaining the orientation of a drill relative to a plane, the device being capable of being connected to the drill, the device having a laser distance measuring unit by which, from a prespecified position relative to the plane, a first distance to a first point in the plane and a second distance to a second point in the plane can be measured, and having an evaluation unit that is configured such that on the basis of the first distance and the second distance the orientation of the device relative to the plane can be ascertained.

A laser alignment system is affixed to a drilling machine M, the laser alignment system contains: a base, two first fixers, two lamp holders, two second fixers, two first resilient elements, two first adjustable screws, two second resilient elements, and two second adjustable screws. The base includes two symmetrical holding sections, two extensions, and two peripheral orifices. Each first fixer has a first arcuate portion, an accommodation hole, a first threaded hole, a limitation hole, a first protrusion and a second protrusion. Each lamp holder includes a peripheral knob, a first receiving orifice, a first rotation portion, a second rotation portion, and a swing portion. Each second fixer includes a second arcuate portion, a second receiving orifice, a first projection and a second projection.

A positioning aid is disclosed for a core drilling machine, having a core drill for creating a hollow-cylindrical drill hole. The positioning aid includes a light source for creating a centring pattern on a workpiece. The positioning aid is fastened in a releasable and centered manner to the core drilling machine. The positioning aid may include a laser pointer, which is releasably fastened to a centring pin.

A drill press laser alignment device includes a rigid plate that is attachable to the column of the drill press above the table. A plurality of cylindrical support posts carried by the plate engage the column to fixedly orient the plate relative to the table. A pair of laser modules mounted rotatably to the plate produce respective planar laser beams that are projected perpendicularly against the table such that the beam appears as a laser line on the table. The laser modules are manipulated to produce a laser crosshair alignment marking wherein the projected laser lines intersect at a point operatively aligned with the axis of the drill bit. This forms a target for accurately positioning a workpiece to be drilled on the table below the drill bit.

A method for manufacturing a cutting tool having a rake face, a flank face, and an edge having a ridge line interconnecting the rake face and the flank face, wherein on the flank face there is a cutting edge region from the ridge line of the edge to a point A away therefrom on the side of the flank face by a distance X, the method comprising producing and processing the flank face with a laser, the producing and processing being producing and processing the cutting edge region along the ridge line of the edge with a first laser beam having a depth of focus equal to or deeper than a width of the cutting edge region when the distance X is the width of the cutting edge region, the distance X being 0.2 mm or more and 5 mm or less.

The different advantageous embodiments may provide an apparatus comprising a vision system, a drilling tool, and a system controller. The vision system may be configured to generate data about a number of laser signatures on a surface of a workpiece. The drilling tool may be configured to drill a number of holes in the surface of the workpiece. The system controller may be configured to generate drilling instructions for the drilling tool using the data generated by the vision system.
