摘要： Provided is a method of phasing a threaded grinding stone, as well as a device therefor, the aforementioned method and device being such that contact or non-contact of a threaded grinding stone with a disk dresser can be detected with high accuracy, with the result that the phasing of the threaded grinding stone can be accurately performed. For the purpose of achieving the above, a threaded grinding stone (14) is phased with respect to a disk dresser (32) prior to the engagement of the threaded grinding stone (14) with the disk dresser (32) during dressing. In performing this phasing, it is determined whether or not the threaded grinding stone (14) contacted the disk dresser (32), on the basis of a voltage (V) which is commensurate with the amplitude of the elastic wave generated in the threaded grinding stone (14) at the time when the threaded grinding stone (14) contacted the disk dresser (32). In a case where the voltage (V) does not exceed a threshold value (Vo) even if the threaded grinding stone (14) contacts the disk dresser (32), then the rotational speed of the disk dresser (32) is increased, with the result that there is forcibly created a situation where it is determined that contact occurred. Subsequently, the threaded grinding stone (14) is positioned, on the basis of the resulting phase thereof, in an intermediate phase where the aforementioned engagement is feasible.

摘要： A gear shaping machine is provided. The gear shaping machine includes a pair of horizontally reciprocating gear shaping heads mounted to a column. Each gear shaping head includes a spindle assembly including an integral rotary drive for indexing the spindle. The spindle assembly is carried by a spindle slide. The spindle slide also carries a plurality of bearing blocks to allow for sliding movement of the gear shaping head relative to rails mounted on the column. A linear drive arrangement is operably coupled between each gear shaping head and the column. The linear guide arrangement allows for controlled linear translation of each gear shaping head independently of one another. Each gear shaping head also includes a back-off mechanism for independently moving the spindle assembly toward the workpiece during a cutting stroke and away from the workpiece during a return stroke of each gear shaping head.

摘要： Provided is a gear processing machine which has a simple configuration, and is capable of processing a gear with high accuracy. For this purpose, a gear grinding machine wherein a tooth alignment operation is performed prior to grinding, is equipped with a workpiece processing rotation shaft (22) which rotates a workpiece (W1) located at a workpiece processing position (P2) ; a workpiece swing device (30) whereby a tailstock (50) that holds the workpiece (W1) is swung between a workpiece replacement position (P1) and a workpiece processing position (P2) ; a workpiece alignment rotation shaft (52) which rotates the workpiece (W1) held by the tailstock (50); and a tooth alignment sensor (43) that detects the rotation phase of the workpiece (W1), which was rotated by the workpiece alignment rotation shaft (52). Before the workpiece (W1) held by the tailstock (50) is placed at the workpiece processing position (P2), the rotation of the workpiece alignment rotation shaft (52) is controlled on the basis of the rotation phase detected, so that the workpiece (W1) will engage with a threaded grinding stone (16).

摘要： To provide a method of controlling a machine tool and a machine tool which allow preventing relieving interference without using a mechanism for causing an offset between a cutter (13) and a workpiece (50) , a controller (40) performs control such that the workpiece (50) is machined by repeating the steps of: machining the workpiece (50) by moving the cutter (13) for machining the workpiece (50) in a direction parallel to a rotational axis of the cutter (50) while rotating the workpiece (50) together with the cutter (13); and returning the cutter (13) to a machining start position again after termination of the machining step, and performs offset control such that the cutter (13) is moved away from the workpiece (50) in a rotation direction of the cutter (13) upon the termination of the machining step.

摘要： A numerical controller capable of reducing machining time in synchronization control machining. A workpiece (1) already rough-machined into a shape of a gear, and a tool (2), are rotated in synchronism. Proximity limit distance Lt ensuring that the workpiece (1) and the tool (2) do not interfere with each other, approach amount Ap required to bring the workpiece (1) and the tool (2) into a positional relationship for performing normal gear machining (condition in which the workpiece engages with the tool), and phase shift amount Fs corresponding to the depth of cut are given as commands. In parallel with approach motion, phase adjustment motion for making the workpiece (1) face a tooth space of the tool (2) is performed. When the approach motion progresses by the proximity limit distance Lt, if the phase adjustment is completed, the approach motion is continued without interruption. If not, the approach motion is interrupted, and resumed after the phase adjustment is completed. After the approach motion is completed, phase shift is performed to give a cut, and machining is performed. When cutting loads become a certain value or smaller, it is determined that the machining is completed. Since the approach motion and the phase adjustment are performed concurrently and completion of machining is automatically determined, the machining time can be reduced.
摘要翻译：一种能够减少同步控制加工时间的数值控制器。已经粗加工成齿轮形状的工件（1）和工具（2）同步旋转。接近极限距离Lt确保工件（1）和工具（2）不彼此干涉，使工件（1）和工具（2）进入正常齿轮加工的位置关系所需的接近量Ap （工件与工具接合的状态）和与切削深度对应的相移量Fs作为指令。与进场运动并行，执行用于使工件（1）面对工具（2）的齿空间的相位调整运动。当接近运动进行接近极限距离Lt时，如果相位调整完成，则连续运动不间断地继续。如果没有，则进场运动中断，并在相位调整完成后恢复运行。进场运动结束后，进行相位切换，进行加工。当切削负载变为一定值或更小时，确定加工完成。由于进行运动和相位调整同时进行，并且自动确定加工的完成，因此可以减少加工时间。

摘要： A spindle (60) for a machine tool comprising a rear spindle portion (62) and a forward spindle portion (64) with each of the rear spindle portion and the forward spindle portion being rotatable about the same axis relative to one another. The inventive spindle includes one or more spring elements (68) extending between the rear spindle portion and the forward spindle portion whereby with the forward spindle portion and the rear spindle portion rotating at a predetermined amount and with the rotation of the forward spindle portion being constrained at that amount, an additional rotation applied to the rear spindle portion results in a deflection of the springs thereby effecting a torque between the forward and the rear spindle portions. The present invention also includes a control method which has as its objective to control the position of, not the torque applied to, one of the spindles, usually the gear member spindle. In this method, the gear member spindle position is controlled relative to the pinion member spindle position by means such as computer numerical control (CNC). As the pinion member is turned at some speed, the gear member is kept in coordination with the pinion (according to their ratio) by the CNC control. The gear member spindle can be commanded to include additional rotational components which, in effect, advance or retard the gear rotation relative to the pinion.

摘要： A method for machining straight toothed conical gear wheels (1). At least one part of the tooth profiles are milled with a milling cutter (2), the left tooth profiles are milled at a different moment from the right tooth profiles, the machined conical gear wheel (1) is rotated at an angle between the milling of one left tooth profile and the milling of a right tooth profile, and the inclination of the milling cutter axis remains unchanged during the milling of said gear wheel. The angle of rotation is not a multiple of the base pitch α .
