摘要： An apparatus and method are provided for performing multiple machining operations on a workpiece such as a crankshaft. Oil holes may be drilled in a crankshaft by a tool shifted along a curved path between successive, acute angle tool plunging locations. The tool's carrier is shifted parallel to the crankshaft axis and the tool carrier is rotated to the desired acute angle about a point on the crankshaft axis for each of successive oil hole drilling locations thereby reducing programming needed to drill the oil holes at the specified angles. Offset tolerance errors are reduced by a large factor as the tool is plunged from an outer initial position toward the crankshaft axis.

摘要： 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.
摘要翻译：提供了一种用于产生偏心凸轮轴凸角的铣削装置和方法，其具有平行于凸轮轴的水平轴线的周边表面，优选地为凸角的整个360°圆周表面。在一种形式中，铣刀在铣削期间移动，使得切削刀片切割总是平行于凸轮轴轴线的凸角上的外周表面。刀头可以倾斜以保持切割边缘平直于凸轮轴轴线，并且当切割头枢转切割边缘时，切割头也可以横向移动，刀具的宽度覆盖凸缘的外周表面的宽度。如果偏心凸角是切割边缘不覆盖凸缘的整个宽度的重大形状，则可以以内插方式使用第四轴线，以保持切割刃始终桥接凸角表面。

摘要： A method and apparatus are provided for rolling outer fillets of arcuately offset, split pin bearings on crankshafts with a pair of work rollers, each pair engaging and rolling a respective outer pin fillet. A backup roller is positioned opposite the pair of work rollers. The work rollers may be positioned above and below a centerline of the split pin, preferably about 90° apart. The work rollers can perform identical rolling operations at identical pressure and the work rollers and backup rollers are positioned to keep the adjacent tool heads in parallel planes during these rolling operations. Rolling arms carry the tool heads and stops are provided to keep rear portions of the tool arms in parallel planes against sideways forces. The work rollers and the backup roller may be mounted on the same tool arm and are movable relative to each to clamp or release a pin bearing.
摘要翻译：提供了一种方法和装置，用于在一对工作辊上滚动曲轴上的弧形偏移的分离销轴承的外圆角，每对工作辊啮合并滚动相应的外销脚。支撑辊位于一对工作辊对面。工作辊可以位于分开销的中心线的上方和下方，优选地相距约90°。工作辊可以在相同的压力下执行相同的轧制操作，并且工作辊和支撑辊定位成在这些轧制操作期间将相邻的工具头保持在平行的平面中。滚动臂携带工具头和止动件，以将工具臂的后部保持在平行的平面上，防止横向力。工作辊和支撑辊可以安装在相同的工具臂上并且可相对于每个工具夹持或释放销轴承。
