46 VERFAHREN ZUR FEINBEARBEITUNG VON KURBELWELLEN UND BEARBEITUNGSZENTRUM DAFÜR EP05773760.3 2005-07-22 EP1907156A1 2008-04-09 FAIGLE, Bernd; MÄRKER, Wolfgang
The aim of the invention is to provide a machining sequence which enables the grinding process during the production of crankshafts to be completely eliminated. The fine machining is preferably achieved by dry machining and orthogonal rotational milling, all main bearings (37-39) and lifting bearings (48-51) being machined in a single clamping from the rough-machining dimensions to the final dimension. For a second machining sequence, some of the main bearings and lifting bearings are used as clamping surfaces, thus avoiding measuring chains. Compensation measures for compensating the flexibility of the crankshaft ensure dimensional accuracy of the crankshaft, even under large-scale production conditions.

48 SCHNEIDEINSATZ UND ZUGEHÖRIGES FRÄSWERKZEUG EP01923564.7 2001-02-09 EP1253989A1 2002-11-06 WERMEISTER, Günter
The invention relates to a cutting insert used for cutting metal, especially for milling for example camshafts. The inventive insert comprises at least one cutting edge (4, 4') that is formed by the intersection of a face (2) with a flank (3). The aim of the invention is to provide a cutting insert for a milling cutter and a corresponding milling cutter the noise level of which, even if at full load, is considerably reduced for high-speed milling. To this end, the cutting edges (4, 4') extend at an angle deviating from 90° relative to the cutting direction of the cutting insert.

54 Method of and Apparatus for Milling Workpieces Such as Camshafts US11939230 2007-11-13 US20080101880A1 2008-05-01 Bramwell Bone
A milling apparatus and method are provided for generating eccentric camshaft lobes with a peripheral surface that is parallel to the horizontal axis of the camshaft for preferably the entire 360° peripheral surface of the lobe. In one form, the cutter is shifted during milling so that the cutting insert is cutting the peripheral surface on the lobe that is always parallel to the camshaft axis. The cutter head can be tilted to keep the cutting edge straight and parallel to the camshaft axis and, as the cutting head pivots the cutting edge, it also moves sideways with the width of the cutter covering the width of the lobe's peripheral surface. If an eccentric lobe is of a drastic shape where the cutting edge does not cover the entire width of the lobe, a fourth axis may be used in an interpolative manner to keep the cutting edge always bridging the lobe surface.

60 Cam milling machine US631202 1984-07-16 US4614467A 1986-09-30 Masayoshi Takagi; Takehiko Hayashi; Fumio Sakamoto
A cam milling machine having a headstock and a tailstock, which are fixed on a bed and are horizontally spaced from each other for carrying at a time two camshafts to be rotatable respectively on their axes which extend horizontally in parallel relation with each other. A tool support carrier is guided on the top of the headstock and is movable by an index feed device in a horizontal direction parallel to the axis of each camshaft. Two tool supports each carrying a milling cutter are carried on the tool support carrier to be vertically movable by respective tool feed devices, each for moving the milling cutter associated thereto toward and away from one of the camshafts. The tool support carrier is moved by an index feed device in the axial direction of the camshafts so that each milling cutter is selectively brought into alignment with one of cams on each camshaft. Further, transfer bars horizontally extend across the space between the headstock and tailstock, so that unfinished camshafts are loaded two at a time into the machine from the front of the machine and after machining, are unloaded from the rear of the machine.
