The flow of heat energy from the cutting edge rim of a self-propelled round annular rotary cutting element (“insert”) to axial-load and radial-load bearings in a cartridge which rotatably supports the insert on a machine tool body is reduced by defining heat flow paths from the insert rim to cartridge components which engages the bearings to have low thermal conductance relative to heat flow paths from the insert rim to other parts of the cartridge. Control over heat flow path thermal conductance is obtained by selection of materials used between the insert rim and the mentioned cartridge components, by reductions in the cross-sectional areas of the critical heat flow paths, and by combinations of those two techniques. Protection of the bearings from heat enables the insert and the cartridge to be reduced in size. Improved mountings of insert-supportive cartridges to tool bodies are disclosed.

A fly-cutting system is disclosed, and in particular one that comprises a dynamically-controllable actuator for controlling the position, orientation, or both position and orientation of a cutting element carried by a fly-cutting head. In certain embodiments, the actuator can adjust the position or orientation of a cutting element, or both, hundreds or thousands of times per second, enabling precise control over the shape of features formed by the cutting element in a surface of a workpiece. 1. A method of manufacturing a microreplication tool , the method comprising:sending, with a control system, a first set of electronic signals to operate a motorized spindle to rotate a cylindrical workpiece mounted to the motorized spindle; a cutting element mounted to an outer radius of the fly-cutting head; and', 'a dynamically-controllable actuator, positioned between the axis of rotation and the cutting element and radially spaced from the axis of rotation;, 'sending, with the control system, a second set of electronic signals to operate a continuously rotatable fly-cutting head to form one or more features in the workpiece, the fly-cutting head being rotatable about an axis of rotation, wherein the fly cutting head includesmonitoring, with the control system, angular positions of the fly-cutting head while operating the fly-cutting head;sending, based on the monitored angular positions of the fly-cutting head, with the control system, a third set of electronic signals to operate the dynamically-controllable actuator to trace a controllable, predetermined cutting path relative to the position and rotation of the workpiece by changing a position of the cutting element relative to the fly-cutting head during a cutting operation.2. The method of claim 1 , wherein sending the third set of electronic signals to operate the dynamically-controllable actuator comprises sending the third set of electronic signals via a slip ring to transfer the third set of electronic signals from ...

The embodiments described herein relate to methods, systems, and structures for cutting a part to form a highly reflective and smooth surface thereon. In some embodiments, the part includes substantially horizontal and vertical surfaces with edges and corners. In described embodiments, a diamond cutter is used to cut a surface of the part during a milling operation where the diamond cutter contacts the part a number of times with each rotation of the spindle of a milling machine. The diamond cutter has a cutting edge and a land. The cutting edge cuts the surface of the part and the land burnishes the surface of the part to form a highly reflective and smooth surface. Thus, the diamond cutter cuts and burnishes portions of the part, thereby eliminating a subsequent polishing step.

Double-sided, indexable turning insert

Номер: US20140286718A1

Автор: Maths Scherman, Ronnie Löf

Принадлежит: Sandvik Intellectual Property AB

A double-sided, indexable, polygonal turning insert includes a plurality of corners, a peripheral clearance surface, and identical upper and under sides. Along the upper side and underside, primary cutting edges, which individually include a nose edge situated in a corner and two main edges, converge toward the same and transform into auxiliary cutting edges, which separate each pair of primary cutting edges along one and the same side. Chip-directing guide surfaces are placed inside the chip surfaces of the cutting edges. The primary cutting edge has a generally positive cutting geometry such that a wedge angle of the cutting edge between the chip surface and the clearance surface is acute in arbitrary sections along the nose edge, as well as along the two main edges. In such a way, the primary cutting edge produces chips that can be guided in a careful, although distinct, way by the guide surfaces.

A clearance angle, of a blade-like tool or tool tooth of a tool for hob peeling workpieces is determined by defining the rake face contour of the tool and calculating the progression of path movement of the rake face during chip-breaking hob peeling, taking into account a pre-determinable transmission ratio between the tool and the workpiece determined by the respective number of teeth, and the desired tooth cross-section contour of the tool, and determining a tangential speed for points of the cutting edge of the tool during chip-breaking, wherein hob peeling is determined in the form of vectors that are displayed graphically as bundles for each point on the cutting-edge and a closed envelope surface is determined, which plus a desired clearance angle is selected as the shape for the flank face contour of the tool or of the flank face of the tool tooth. A tool is also provided. 1. A tool for gear skiving , comprising:a plurality of teeth, each of the teeth having faces with cutting edges and adjoining flank faces, the teeth being arranged on a cylindrical or conical shell, wherein the tool can be driven rotatingly about a tool rotational axis spaced a radial distance away from a workpiece axis and can be advanced in rolling engagement at a crossed-axes angle between a rotational axis of a driven workpiece and the tool rotational axis, wherein a closed annular envelope surface, within which no tangential velocity vectors lie and in relation to which the flank face of the respective tooth is inclined by 2° to 10° is formed by a bundle of tangential velocity vectors of each cutting edge point.2.
