| 181 | Method and device for detecting contact between tool and workpiece fastened on processing machine | JP2002182749 | 2002-06-24 | JP2003025187A | 2003-01-29 | ULBRICH DIETER |
| PROBLEM TO BE SOLVED: To provide a method and device for easily and accurately detecting the first contact between a cutting tool of a machine tool and a workpiece without damaging the workpiece. SOLUTION: A high frequency electric signal or a solid borne sound signal is applied between a position 8 on the tool 4 of the machine tool 1 and a position 9 on the workpiece 5. Unless the tool has contact with the workpiece, a resistance between both positions is high because it is a resistance of a signaling channel 11 passing through the machine. However, when both have contact with each other at a position 10, a signalling channel 12 having a low resistance is established in parallel to the signalling channel 11 to produce a great change in signal at positions 8, 9. The signal changes are evaluated by a signal evaluation device 16 and an output signal 17 therefrom is fed to a machine control device 18 which controls the movement of a spindle of the machine tool 1. | ||||||

| PROBLEM TO BE SOLVED: To provide a device for judging an axial position of a tooth of a work on a machine and to set the work and its method. SOLUTION: Starting and finishing positions in positions in the axial direction of works 11, 18 of a working program of a gear manufacturing device are judged by using a laser beam 14 vertically irradiated on axes of the works, and a position of this beam against standard points of tools 5, 17 are known. The beam 14 and one or both end surfaces 16 are made to match with each other by alternate movement in parallel with the axes of the works. A position in the axial direction provided in this way is transmitted to a mechanical control system. In the same way, decision of a position in the axial direction of the tool is practiced by vertically irradiating the laser beam against an axis of the tool on a circumferential surface of the tools 5, 17. | ||||||

| PURPOSE:To improve grinding accuracy by detecting a mating state between a whetstone and a gear to be processed as a quantity of electricity, and avoiding the use of a tooth of a gear corresponding to a maximum amount of electric power. CONSTITUTION:The captioned device includes a driving source for tool 34 for rotating a rotary tool 36, a driving source 22 for work that is connects to a work 20 via a clutch mechanism and allows the work 20 to be rotated, a detecting circuit 54 that is connected to the driving source for tool 34 and detects an increase of a load against said driving source 34, and a cricuit for energyzing the clutch mechanism 48 while delayed from the time of a prescribed increase of the load detected by said detecting circuit 54. Provided from the time a driving current of a whetstone motor 34 becomes a maximum, a corresponding tooth of a gear 20 is slightly displaced, and the clutch 48 is thrown in with synchronization therewith, mating between the whetstone 34 and the gear 20 is avoided, enabling a gear grinding machine to be obtained, which can provide a proper grinding margin. | ||||||

| PURPOSE: To simplify a mechanism by changing a set value of an indexing counter in responce to the number of revolutions of a transverse motor. CONSTITUTION: A pulse is generated from a second pulse generator 42 which is connected to a third rotation driving source 18 for displacing a gear 20 to be processed with respect to a whetstone 36 and is adapted to generate a prescribed pulse in responce to the number of revolutions of said driving source. The pulse is added to another pulse with is generated from a first pulse generator 40 connected to the whetstone 36 brought into rotation by a first rotation driving source 34. The added result is introduced into a second rotation driving source 22 which brings the gear 20 to be processed into revolution and forces it to be engaged with the whetstone, and thereby the second driving source is controlled in its rotation, thus allowing the gear to be processed to be processed. Hereby, a mechanism of the capationed device can be simplified without the need of plural differential gears. COPYRIGHT: (C)1985,JPO&Japio | ||||||
| 187 | Gear shaper with relieving interference detecting function | JP19336183 | 1983-10-18 | JPS6085823A | 1985-05-15 | KIGAMI YUKIO |
| PURPOSE:To obviate the superfluous wastage of a tool and a machine itself befor it happens, by detecting the presence of relieving interference accurately and speedily, while constituting a gear shaper so as to stop its gear cutting at once, of the gear shaper provided with a relieving interference detecting function. CONSTITUTION:When a relieving interference happens in a cutter 3, this cutter 3 and a work 15 come into contact with each other whereby torque FR in the same direction as feed component force or in the reverse direction is added to the cutter 3 being in its return stroke. In this case, the torque FR by means of the relieving interference is generated in the reverse direction against the cutting resistance. If suchlike torque happens, sampling voltage grows larher than a threshold value. Therefore, a warning indicator lamp is lighted and simultaneously gear cutting is stopped by a control part. With this constitution, the superfluous wastage of a tool and a machine itself can be obviated before it happens. | ||||||

| A device for phasing a threaded grinding stone is phased with respect to a workpiece or a disk dresser prior to the engagement of the threaded grinding stone with the workpiece or with the disk dresser during grinding or dressing. In performing this phasing, it is detected, by means of an AE fluid sensor provided to a grinding stone head which rotatably supports the threaded grinding stone, whether the threaded grinding stone has had contact with the workpiece or the disk dresser. Subsequently, on the basis of the phase of the threaded grinding stone at the time when contact was detected, the threaded grinding stone is positioned in a phase where the aforementioned engagement is feasible. | ||||||

| Provided is a gear grinding method wherein an initial cutting position by a grindstone is appropriately set, resulting in an improvement being able to be made in machining accuracy. For this purpose, the gear grinding method is such that rotation of a workpiece (W) about a workpiece rotation axis (C), cutting by a grindstone (15) in the X-axis direction, and feeding of the grindstone (15) in the Z-axis direction are controlled, resulting in the workpiece (W) being ground by the grindstone (15). In this method, measurement points (P1-P9) are set in a grid-like pattern on a left tooth surface (WL) and a right tooth surface (WR) of a predetermined tooth (Wa) of the workpiece (W); rotation phases about the workpiece rotation axis (C) at the measurement points (P1-P9) are detected; tooth thickness deviation amounts (e) between a reference involute tooth surface and the measurement points (P1-P9) on the left and right tooth surfaces, as well as tooth thickness deviation amounts (e) between the involute tooth surface and corresponding points (Q1-Q9) on all teeth other than the tooth (Wa), are obtained on the basis of the detected rotation phases; and an initial cutting position (X1) for the grindstone (15) is set on the basis of the largest of the deviation amounts (e). | ||||||

| A method of determining a desired power level (P) as a function of relative tool to workpiece position, thereby enabling adaptive control advantages that were previously inaccessible for machining, such as bevel gear grinding, from solid applications. Preferably, set point power is expressed as a function of specific power (P′, P″) and roll position (Q) for a generated gear or as a function of specific power and plunge position for a non-generated (i.e. Formate) gear. Specific power is defined and preferably remains as defined during machining even as process conditions vary during machining. | ||||||
