41 Turn broach abnormality sensing apparatus US09091161 1998-06-09 US06201567B1 2001-03-13 Yoshiaki Kuroda
A turn broach abnormality sensing apparatus is provided for use in a turn broach for cutting a rotating workpiece (3) by rotating a broach cutter (18) that comprises a plurality of unitary cutters (18b) axially coupled together, each having a plurality of tip rows (181, 182, . . . 18n) arranged on, a peripheral surface thereof in the form of a helicoid. The abnormality sensing apparatus includes a plurality of image pickup means (23) disposed corresponding respectively to the unitary cutters (181, 182, . . . 18n) of the broach cutter (18b) for sensing an image of each of individual tips on the respective tip row of each of the plural unitary cutters, a focusing adjustment means (27) for maintaining a distance between the image pickup means (23) and each individual tip on the respective tip row of each of the unitary cutters, substantially constant, and an abnormality sensing means for image processing the image picked up by the image pickup means (23) of each individual tip to determine an extent of wear thereof or damage thereto, thereby ascertaining an abnormality of each of the individual tips.
42 Machine for turn broaching crankshafts with rotationally symmetrical surfaces US395389 1995-02-27 US5743688A 1998-04-28 Herbert Kiefer; Herbert Klemisch; Kurt Rohr; Rolf Santorius; Manfred Schuler; Wolf-Dietrich Voss
A machine and a process of using the machine for turn-broaching a workpiece to for crankshafts or camshafts. The machine comprises turn-broaching units having peripheral cutters whose cutting surfaces are monitored and automatically adjusted to compensate for wearing. The angular positions of the cutters of a turn-broaching unit may also be offset with respect to one another such that only one cutter is in contact with the surface of the workpiece at each instant.
43 Method for machining a radially symmetrical workpiece surface and a tool for performing the method US969016 1992-10-30 US5373631A 1994-12-20 Karlheinz Schmid
A method for machining a rotation-symmetrical workpiece surface includes the steps of rotating the workpiece during machining, roughing the workpiece surface, smoothing in a longitudinal turning process the workpiece surface with a cutting tool having a cutting blade with a divided edge arrangement, advancing the cutting tool in a radial direction relative to the workpiece surface in the smoothing step, and moving the cutting tool in the axial direction of the workpiece surface for carrying out the longitudinal turning process. The cutting tool for carrying out the aforementioned method comprises at least one first cutting blade for the smoothing step, the first cutting blade having at least two adjacent edges axially spaced at a distance from one another.
44 Method of machining round material or the like by the whirling process US802241 1991-12-09 US5238337A 1993-08-24 Walter Nussbaumer; Karl-Heinz Beyrer; Josef Mark
A method for machining round material and in particular tubes by the whirling process, in which the whirling tool is designed as an annular cutting tool having an internal tooth system. The center point of the whirling tool is guided from the start on a path or curve so that a tube wall, for example, is not cut through by a linear feed but by a curve-like feed. This curve is followed via a CNC system. Due to the whirling process, which starts immediately, the length of cut of the tool in the workpiece is given a virtually uniform value just after the start of machining so that the chip volume can be optimized. In this way, the radial and tangential forces on the tool can also be reduced, which leads to optimization of the tool.

46 Tool-outfitted turn broaching machine US466896 1990-01-18 US5030049A 1991-07-09 Wolf-Dieter Voss
A turn broaching machine can be used either as a single turn broaching machine or as a set turn broaching machine with a minimal retooling expense by employing two independently movable tool supports into which either a single turn broaching tool or a turn broaching tool set can be inserted, where the ends are designed so they are suitable for chucking in the chucks of the two tool supports.
47 Machine tool for broaching crankshaft connecting rod bearings US109934 1987-10-16 US4895057A 1990-01-23 Garri Berstein; Hans W. Obrig; Helmut Wittkopp; Hermann Wolters
The known turn broaching of crankshaft main bearings is not suitable for broaching crankshaft bearing pins for the connecting rods because that would require locating the rotational axis of the crankshaft in the connecting rod bearing pins, whereby the crankshaft would rotate eccentrically. The resulting unbalances prevent driving the crankshaft with the r.p.m. required for the turn broaching operation. To avoid this problem a broaching lathe for the rotational or turn broaching of crankshaft connecting rod bearing pins is equipped with a steady rest including a rotating support device which permits mounting the crankshaft in the lathe in such a way that the rotational axis coincides with the axis of the connecting rod bearings of the crankshaft.
48 Method of designing a turn broach US239806 1988-09-02 US4841820A 1989-06-27 Brian D. Kaminski; Pulak Bandyopadhyay
An improved cutting tooth configuration in which, unlike the conventional, straight line tool pattern with its constant tool rise, each tooth is incrementally advanced relative to the prior tooth by an amount that progressively decreases. This accounts for the variations in reaction force on the cutting teeth caused by workpiece deflections, so that the net thickness of material removed by each cutting tooth remains relatively constant. Instability and variation in the cutting force is thereby avoided, and tool wear is decreased.
49 Crankshaft broaching machine and method US93084 1987-08-28 US4801226A 1989-01-31 Patrick J. Gleason
A broaching machine and method for machining main bearings and crankpin bearings on a crankshaft for an automotive engine wherein a plurality of removable cutting tool inserts are arranged on a horizontally reciprocating slide below a rotating crankshaft to machine a plurality of bearings and distribute machining forces over the machining operation during a single pass of the slide. The slide also serves as a transfer device for loading and unloading crankshafts into the machine. An air bearing can be developed between the slide and the tooling to assist the operator in removing the tooling from the slide.

56 Repetitive rotary broaching US15082200 2016-03-28 US10029321B1 2018-07-24 Brian E. McCarthy
A broaching tool is held during the conduct of repetitive duplicate rotary broaching operations on serially presented workpieces. The broaching tool is engaged serially with each workpiece for rotation with the engaged workpiece during a corresponding rotary broaching operation. Each workpiece has a given configuration and the broaching tool has a prescribed configuration placed at an initial orientation for establishing a broached configuration placed at a same predetermined orientation relative to the given configuration of each workpiece. Upon completion of a rotary broaching operation on a workpiece, the broaching tool is returned to the initial orientation of the prescribed configuration in preparation for a duplicate rotary broaching operation on a subsequent serially presented workpiece.
57 Method and tool for producing a surface of predetermined roughness US12362528 2009-01-30 US09643265B2 2017-05-09 Holger Ast; Lutfi Bozkurt; Peter Sommerfeldt; Horst Reimann; Bernhard Gand; Frank Orlamünder
For producing a cylindrical surface that has a surface structure of predetermined geometry suitable for application of material by thermal spraying, a geometrically predetermined groove structure of minimal depth and width is introduced into the surface by a tool embodied as a follow-on tool in that a groove cross-section is processed successively to a final size. In order for the surface to be producible in mass production with constant quality, the groove structure is worked in such that first a base groove is introduced with a groove bottom width that is smaller than the groove bottom width of the finished groove. Subsequently, at least one flank of the base groove is processed for producing an undercut groove profile by a non-cutting action or cutting action wherein the introduced groove structure is deformed in such a way that the groove openings are constricted by upsetting deformations of material.
