The radial positioning of the whirling head determines the depth of the grooves that are produced.

In the described way, the straight jointing stone 25 oscillates without radial advancement in the axial direction.

The smooth cutting edge 9 is achieved by the axial stroke movement of the jointing stone 25 without radial advancement.

Besides, the overall dimensions of this chuck design are very large in the axial and also in the radial directions due to the rod type centering jaws inclined to the longitudinal axis of the chuck. However, the clamping range is small because the radial feed of the jaws depends on the slant of the centering jaws.

A further advantage of this structure according to the invention is that the setting of the desired workpiece diameters can be simplified greatly in a structural respect without there being any change in the rigidity inherent in the structure, since the tool can be set with respect to the workpiece by a radial adjustment.

To determine the required radial feed movement 38, a diameter measuring device 42 may be positioned at a point on the circumference of the dressing roller 19.

A radial in-feed which is too quick would not only increase the chip thickness to unacceptable levels but also, above all, the corollary transverse forces which are introduced into the workpiece would become relatively high, due to the chip length, which is then considerable owing to the relatively great wrap between a disc-like external-milling cutter, which rotates about an axis parallel to the bearing-journal axis, and the current machining point.

The crowning in the middle of the tooth height, i.e. the middle between the tip cylinder and the root cylinder, corresponds to the desired value, but the inclination of the plane of action leads to an undesirable distortion at the tip and root since the radial feed for generating the longitudinal crowning is only correct for the middle of the tooth.

Once the bending roller 13 and the shaping roller 14 have reached their end positions, the pressing member 5 is moved counter to the action of the compression springs 31 relative to the workpiece 17, without the slide 11 undergoing any further radial advancing in the direction of the workpiece 17 .

For example, in this case, the distance can initially be kept constant, and a radial feed can take place with progressive machining.

In order to process a large number of different cable harness types with one processing unit, a controlled radial feed of the nozzles in the direction of a central axis is provided.

Rather, the radial setting during the grinding via the wheels has been made superfluous by virtue of the fact that the rod-shaped workpiece runs through wheel groups with an increasing diameter, the grinding gap becoming narrower and narrower.

The outward radial adjustment of the cutting material elements is continued until the cutting material elements reach a previously defined first radial position (FIG.

In this case, it is possible to move with a step motor and a threaded spindle the pressure rods with the desired precision and repetition accuracy in axial direction relative to the base member so that, by means of the deflection with the feed cone and the feed slants, the desired radial feed action of the machining tools is achieved.

In conventional multiple cut machining, the machining depth for the individual cuts is produced by the radial infeed with respect to the workpiece 50 .

Accordingly, the proposed concept provides the possibility after the actual dressing and out of meshing of dressing tool and grinding worm to rotate and to shift respectively the grinding worm by one or more partitions (channels) so that at the subsequent dressing stroke, which preferably takes place without selective (radial) infeed, other grooves of the dressing tools come into contact with the channels of the grinding worm.

The invention has been explained above with the help of an exemplary embodiment in which locking is achieved by a radial feed of the brake member to the locking sleeve.

The axes of the locating channel and of the opening in this case are advantageously arranged perpendicular to one another, in order to allow a radial feed of the brake member.

Now, the pivoting around the axis of rotation A takes place for a certain radial infeed X in such a way, that the first abrasive area 6 contacts the first flank 3 and simultaneously the second abrasive area 7 contacts the second flank 4 .

The design of the cutting bit according to the invention enables the cutting bit to be inclined somewhat downwardly relative to the feed direction, wherein a free surface is prepared for improved radial feed of the cutting bit to the work tool or to the work piece surface for machining, on the one hand, whilst it is still possible to maintain a positive cutting edge geometry whereby the cutting forces occurring are reduced.

The corresponding method uses a cutting bit and a cutting tool of the afore-mentioned kind, wherein the radial feed of the cutting bit towards the work piece surface is such that the top and bottom surfaces are inclined such that they fall away to the front relative to that feed direction.

FIG. 5 also shows an actuator element 26 which can also be a pneumatic actuator element, for example, and by which, inside the equalizing station 14, the radial feed motion of the roller 13 is controlled to achieve the most constant possible movement of the film strip.

The adjustability of the first section provides here the radial feeding of the cutting or welding torch, while the other two sections permit substantially the changing of the orientation of the cutting or welding torch in relation to the surface of the workpiece.

Here, the adjusting devices provided individually for each holder according to the first embodiment are therefore replaced with pressure pieces which are moved by a central adjusting device and effect the elastic deflection of the holder, resulting in a radial infeed of the cutting tips for producing a bore diameter different from that set beforehand.

This is necessary since a hook-like turning tool is inserted into the recess for manufacture of the cooling channel open to the bottom and the cooling channel must be hollowed out into its required form by appropriate axial and radial infeed.

In particular, the radial advance of the clamping jaws, which must take place synchronously to achieve central clamping of the sleeve, is undertaken with the help of a hydraulic circuit by means of which a clamping piston allocated to each clamping jaw is moved axially in the pivoting ring, with the clamping piston making contact with one of the clamping jaws in such a way as to provide an active driving effect.

In the so-called plunge-cut phase, in which radial feed only of the tool T takes place, preferably the two edge areas of the workpiece W are machined by the outer layers b and c. If the plunge-cut phase has ended, a more or less even amount of metal is removed from the tooth flanks, as is shown in FIG. 5 .

The machining tests were performed under the following conditions: workpiece steel DIN 1.2344 hardened to 45HRC, tool diameter 10 mm, solid cemented-carbide milling cutter, cutting speed 220 m/mm, feed per tooth 0.1 mm, axial infeed 10 mm, radial infeed 0.5 mm.

Avoiding tilting of the cutting material elements during the radial adjustment means that uneven wear can be avoided.

The condition attained after this procedure following radial infeed of the grinding wheel is shown in FIG.

Through an axial shift of the press cylinders in relation to the spindle and a radial infeed of the press cylinders, the desired shape of the workpiece is attained, in the course of which the internal shape is developed that corresponds to the matrix.

The essential aspect of the inventive method and of the inventive device resides in the fact that by a movement of a profiled tool in rolling contact with a simultaneous radial feed the tooth shape with oblique entry surface and undercut, that is required for change speed gears, can be manufactured at low cost with application of simple tools,

In order to provide a compensation for the centrifugal force when the sliders because of radial adjustment no longer are all at exactly the same radial spacing from the rotation axis and thus such that the centrifugal force does not act equally upon all of the sliders and cannot be balanced by identical positioning of the sliders, an additional centrifugal force balance system has been disclosed in the German Patent Document DE 101 33 856 A1.

According to the invention an extremely economic method is obtained in that the inner collar and/or the outer collar undergoes shaping in a radial infeed by means of a spinning roller, which has an outer contour corresponding to a desired collar shape.

Recently developed alternative prediction methods enable to consider the instability of Flip-Bifurcation in addition to Hopf-Bifurcation, which occurs with the decrease of radial depth of cut.

This research work proves the semi-discretisation-method’s validity independently of radial depth of cut thus its universally valid character for the prediction of process stability in high-speed-milling processes.

Particularly in FIG. 15.2-5 on page 536, the example of a radial infeed in three equidistant infeed steps is used to explain that after the first infeed step in the height direction of the tooth, the engagement of the appropriately profiled tool covers only the area at the foot of the tooth flank and reaches the area at the head of the tooth flank only in the course of the further infeed steps.

With radial infeed, if the iteration does not converge, then the difference between the magnitude of the design angle and the magnitude of the helix angle is not large enough. Accordingly a grinding wheel with a design angle of an appropriately selected larger magnitude should be used.

The method can be a single-flank process, but in particular with radial infeed a dual-flank method is preferred.

Secondly, a relative displacement between honing stick and honing-stick opening occurs in the radial direction during radial infeed of the honing sticks, such that the elastomeric material clamped in place in between is subjected to transverse forces which fold or flex the material.

It is also possible to attach two grinding spindles to a single cross slide, which are used simultaneously but with a different radial infeed to two rod bearings having different or identical phase position.
