    摘要： When turning machining is performed on a bag hole where the size of tool insertion hole 5c is smaller than machining diameter D1 of the portion to be machined inside a workpiece with a turning tool 9 having cutting portion 9c at the top end of main body 9a in the shape of a bar, a tool is moved in X-axis direction, in Y-axis direction and in B-axis direction from the tool insertion hole of the workpiece along the tool shape of the tool so as to position cutting portion 9c of the tool on portion to be machined 5e, then, the turning machining is started. The cutting portion 9c of the turning tool can be positioned at the portion to be machined 5e inside the workpiece without the interference between the tool and tool insertion hole 5c of the workpiece by rotating and moving the tool in the B-axis direction. Accordingly, the machining on a bag hole is possible without using a formed tool, as a turning tool.

    摘要： The invention concerns a method and device for producing workpieces with a non-circular internal and/or external shape on a machine holding at least one workpiece (8) driven to rotate at constant speed and at least one tool (5), in particular a machining tool, movend by means of a carriage (3) both radially to the axis of rotation (2) of the workpieces and longitudinally along this axis (2). In order to provide a method which enables workpieces with widely different internal and/or external shapes to be produced on commercially available equipment, the tool (5) is driven to rotate so that its cutting surface describes a circular path, at a constant speed which differs in magnitude and direction from the rotational speed of the workpiece (8), about an axis (6) which differs from the axis of rotation (2) of the workpiece.

    摘要： Pistons and cylinders are manufactured to an oval shape, which is defined as being an oval where the ratio of the major axis to the minor axis is between 1.1:1 and 3:1. Pistons and cylinders are generally finish machined by relative rotation between the tool and the workpiece and movement of the tool in a defined path to produce a finished profile. In general, however, conventional machine tools cannot machine such oval profiles at commercial production rates because of the excessively high tool accelerations which this would involve and of which the conventional machine tools are not capable. Disclosed are a machine tool for machining such oval pistons (23, Fig. 1; 32, Fig. 2) in which an oval piston blank is rotated in a path such that, when each part of the piston surface reaches the tool (24, Fig. 1; 33, Fig. 2), it is at a constant datum position. Thus the tool considers that it is machining a surface of constant radius and normal tool movements can be performed. There is also a boring machine for machining such oval cylinders where the tool (45) is moved in a required oval path. A mechanism (11,11 a, 22, Fig. 1; 28,31, Fig. 2; 37, 39,40,41, 42, Fig. 3) is disclosed which can be used either for turning pistons or boring cylinders to ensure that they are complementary with one another.

    摘要翻译： 活塞和气缸制造成椭圆形，其被定义为椭圆形，长轴与短轴之比在1.1：1和3：1之间。 活塞和气缸通常通过工具和工件之间的相对旋转以及工具在限定路径中的移动来完成加工，以产生成品轮廓。 然而，一般来说，传统的机床不能以商业生产速度加工这种椭圆形轮廓，因为这会涉及过高的刀具加速度，而传统的机床不具备这些加速度。 本发明公开了一种用于机加工这种椭圆形活塞（图1; 32，图2中的23）的机床，其中椭圆形活塞毛坯在路径中旋转，使得当活塞表面的每个部分到达工具（24， 图1; 33，图2），它处于恒定的基准位置。 因此，该工具认为它正在加工一个恒定半径的表面，并且可以执行正常的刀具运动。 还有一种用于加工这种椭圆柱体的镗床，其中工具（45）在所需的椭圆形路径中移动。 公开了一种机构（图11,11a，22，图1; 28,31，图2;图37，图39，图39，图41，图42），其可以用于将活塞或镗缸转向 确保它们是互补的。

    摘要： The invention relates to an apparatus for cutting an oval hole in the wall of a pipe. The pipe secured to a baseplate (1) of the apparatus is cut for an oval hole by means of a tool (20) having its cutter head (24) rotated about its axis while it is driven along a circular path in relation to a carriage (2) of the apparatus. The carriage (2) is mounted on the baseplate (1) by way of linear runners (3). Adapted for rotation along with a drive pulley (4) of the tool (20) is a cogged wheel (10), which through the transmission of a cam lever (11) is adapted to drive a shaft (12) having its rotational motion transmitted on the one hand to drive a gear (22) and on the other hand to work the carriage (2) back and forth in relation to the baseplate (1), a round-trip displacement (2xa) being equal to a difference between the major axis and the minor axis of a desired ellipse.
