Abstract: An apparatus (100) and method (200) of contact machining having applications in profiling operations utilizes at least one static cutting tool (101) and turret (102) driven by rotary motion (103) about a support mechanism (109) for providing sufficient force to achieve deformation by controlled fracturing (523). This allows the separation of material from a workpiece (105) without imposing axial symmetry upon either the cutting tool (101) or the workpiece (105). The apparatus and method mitigates and/or eliminates the adverse effects of plastic deformation (504) while machining a wider range of shapes and materials with greater productivity and precision than existing methods of machining.

Abstract: A non-rotary shaping method (700, 800, 900) and shaping center (600) for forming a part using a non-rotating cutting tool (400) for removing material from a non-rotating workpiece within a three-dimensional work envelope that obsoletes the use of mills for profiling operations. Without the need to rotate to produce sufficient surface footage to remove material, the cutting tool (400) applies constant cutting force to the workpiece along a one-, two-, or three-dimensional cutting path at a sufficiently high feed rate to remove material by means of controlled fracturing instead of plastic deformation. Also, without the need to rotate, neither the cutting tool nor the part are constrained in shape by axial symmetrical. Therefore, parts without any restriction in shape can be produced with finer surface finishes and higher material removal rates than by milling.

Abstract: An angle adjusting mechanism or a linear axis of a processing machine is provided with a reciprocation device. A tool and a tool cutting mechanism are mounted on a moving part of the reciprocation device. A workpiece is processed by the tool based on a combination of the drive of the processing machine and the drive of the reciprocation device.
Abstract: The bead trimmer is preferably applied in a production line for elements having longitudinal weld beads (21), where an element slides along a parallel direction to a longitudinal axis thereof (x), and comprises a tool-bearing turret (2) for removable fixing of a trimming tool (30), associated to a first slide (3) which is slidable along a horizontal direction (y) which is transversal with respect to the longitudinal axis (x) between an internal position, in which the tool (30) is aligned with the weld bead (21), and an external position, in which the tool (30) is not aligned with the weld bead (21). The first slide (3) is associated to a second slide (4) which is vertically slidable on a bearing structure (40) along a vertical direction (z) between a lowered position, in which the tool (30) is in contact with the weld bead (21), and a raised position, in which the tool (30) is distanced from the weld bead (21).
Abstract: An apparatus for resurfacing a pair of guide plugs includes a turntable rotatably mounted on a frame having cutting tools Interacting with resurfaceable guide plugs mounted on a reciprocating slide assembly which includes a guide support block adapted for reciprocating motion with respect to the cutting tools. The block has a pair of saw guides selectively attached thereto so as to be parallel to each other so that parallelism is maintained during the resurfacing process.

Abstract: According to this invention, introduction of dynamic, closed-loop force and position control over press rolls of a planer or infeed table provides a dramatic increase in capability, performance, and reliability, as compared to the prior art.
Abstract: A planing device for planing a first, movable surface of a machine is set forth. The machine includes a second surface from which the first, movable surface can be retracted. The planing device includes a base and a planing assembly. The base is slidably connected to the second surface and partially seated in an interspace formed between the first and second surfaces. The planing assembly includes a stationary planing tool and is connected to the base.
Abstract: A device for engraving intaglio cylinders and similar printing forms having an engraving tool which, together with a sensing member sensing the surface of the printing form to be engraved, is mounted in a holder movable relative to the surface of the printing form. The sensing member is a distance measuring member which contactlessly measures the distance from the surface of the printing form. On the basis of the distance measured from the distance-measuring member, the holder is adjusted relative to the surface of the printing form by an adjusting element, for maintaining a predetermined tool distance between the engraving tool and the surface to be engraved.
Abstract: A tool T is mounted to the tip of the rotatable main shaft S, and at least the rotation angle of the main shaft S is controlled so that the edge of the tool T is always maintained at the right angle against the direction of the tool movement on the machining program locus, when a work W is machined with the edge T.sub.A of the tool T in the state that the edge T.sub.A of the tool T is offset from the rotation center S.sub.0 of the main shaft S.
Abstract: A machine for automatically shaving a large bar of chocolate for forming a thin chocolate shaving that curls into a spiral, for use for decorative purposes. The machine has cutters that will cut an end of a chocolate bar in three separate spirals, on each stroke of the cutter. The chocolate bar is moved a desired distance for new cuts. The knives are partly curved in cross section and have cutting edges that are angled to insure a smooth separation of a thin shaving to form the curl around the curvature of the individual knife. The chocolate temperature is important in cutting, and generally is maintained in the range of 88 to 90 degrees Fahrenheit. The machine itself can be placed in a suitable environment or chamber to maintain that temperature.
