摘要： A cutting insert includes a top face and a bottom face parallel to the top face. Four side faces and four corner faces extend between the top and bottom faces. At least one cutting edge is formed at an intersection of the top face and at least one of the corner faces and two of the side faces connected to the corner face. The top face forms a rake surface, while an upper part of the corner face and the two side faces form a relief surface connected to the cutting edge. In order to reduce the cycle time for crank shaft milling, the cutting insert has two diagonally opposed corners including an acute angle between 70° and 85°. At least one of the acute angled corners including the corner face providing a corner cutting edge. A disc milling tool including such cutting inserts is also provided.

摘要： A method of manufacturing a crankshaft includes the steps of: (1) forming a crankshaft blank via a first half and a second half; (2) measuring a plurality of surface variations between a predetermined surface in a first region and a corresponding predetermined surface in a second region of the crankshaft blank; (3) calculating centering offset data based on the plurality of surface variations; (4) machining a pair center holes based on the centering offset data; (5) machining a counterweight and a journal relative to the pair of center holes to produce a partially machined crankshaft; (5) milling and grinding the partially machined crankshaft to produce a finished machined crankshaft; and (6) rotating the finished machined crankshaft typically on the outermost main journals in a final balancing machine and then modifying the counterweights to eliminate undesirable vibration generated during the rotation and engine operation.

摘要： To increase precision in straightness on a journal thrust surface relative to an outer peripheral surface of a journal in a crankshaft, a control system is provided for controlling movement of a cutter in axial directions by running a control program transferred from an automatic programming apparatus. The automatic programming apparatus corrects machining data on the basis of data for correcting the straightness gained through a comparison between results of a measurement of machining dimensions of the journal thrust surface in the workpiece on which a cutting process has been carried out and target machining dimensions for the journal thrust surface. A control program is prepared on the basis of the corrected machining data after correction of the machining data.

摘要： The invention relates to a tool coupling for connecting a tool carrier which can be driven in a rotating manner, in particular a milling tool with a machine spindle or an adapter connected to a spindle, wherein four drivers in a crosswise formation are provided for transmitting torque between the said parts and in the clamping state engage in four recesses. To allow the tool coupling to be easily operated and to be of a simple construction, and also to counteract undesired jamming, it is proposed that the drivers respectively have on the side transmitting the torque a planar face which lies with full surface-area contact against a wall of a groove-shaped recess in the clamping state, that on the opposite side the driver has a smaller positively or frictionally engaging contact with the wall there of the groove-shaped recess and that a quick-acting clamping device is providing for the axial clamping of the tool carrier and the spindle or an adapter.

摘要： A method of machining a crankshaft from a workpiece whereby all of pin and journal portions of the workpiece are milled and thereby machined with a single crankshaft miller unit. The method comprises: establishing a phase position of the workpiece (3) with a phase positioning jaw (4c) that is provided in one of the chucks (4); clamping the workpiece (3) at its opposed ends with both the chucks (4); milling with a cutter (5e), thereby machining journal and pin portions of the workpiece (3) in succession; after all of the journal and pin portions are milled in the workpiece (3) except a first journal portion (J1) that is located at a position where the phase positioning jaw (4c) and the cutter (5e) may interfere with each other, unclamping the one chuck (4) provided with the phase positioning jaw (4c) and retracting that one chuck (4) to a position at which the jaw (4c) and the cutter (5e) may no longer interfere with each other; clamping again the workpiece (3) at its opposed ends with both the chucks (4); and thereafter milling and thereby machining the first journal portion (J1) with the cutter (5e).
