    摘要: The invention relates to a method for reducing regenerative chatter in that a workpiece (1) rotates in relation to a tool head (2) having at least one chip-removal tool (3, 3a, 3b, 3c) arranged at one end of the tool head (2), the tool head (2) machines walls of the workpiece (1) by means of the at least one chip-removal tool (3, 3a, 3b, 3c), the tool head (2) is vibrationally excited during the machining, a loose additional mass (m
    z ) is moved by the vibration, which additional mass randomly touches the tool head (2) in first positions or randomly has no connection to the tool head (2) in second positions, and thus the total mass of the tool head (2) is randomly changed by the amount of the additional mass (m
    z ) and the vibrational behavior of the tool head (2) is changed because of the mass change and thus counteracts regenerative chatter, and in that a receptacle (51), by means of which the tool head (2) can be exchangeably placed onto a spindle, is arranged at another end of the tool head (2) opposite the one end.

    摘要: Method for reducing milling failure in a machining tool due to coincidence between first vibrations v1 substantially caused by mutually exerted forces between the machining tool and an object being machined, and second vibrations v2 substantially caused by mechanical resonance by or in the the machining tool itself and/or one or more subsystems of the machining tool. The method comprising the steps of detecting frequencies of v1 and the frequencies of v2; determining the extent of the coincidence between the frequencies of v1 and the frequencies of v2. If the extent of coincidence between the frequencies of v1 and at least one of any of the frequencies of v2 is within a certain range, the vibration causing said coincidence between the frequencies of v1 and at least one of any of the frequencies of v2 is counteracted. To counteract said coincidence the respective frequencies of v1 and v2 one or more machining parameters may changed or relevant vibrational characteristics of the machining tool itself are changed by means of passive or active components, e.g. actuators.

    摘要: An engraving head (20) incorporates a shaft (30) which is supported for high frequency oscillation by axially spaced metal spring elements (33), and the shaft is acted upon by improved dampening means (65) to minimize undesirable transverse and transient vibrations. A diamond cutting stylus (45) is carried by a holder (44) mounted within an arm (42) projecting from the shaft to facilitate convenient removal and resharpening of the stylus. A diamond guide shoe (80) has a flat face (81) which engages the surface to be engraved adjacent the stylus and is supported by plate (86) which may be conveniently adjusted without rotation to obtain precision alignment of the face with the surface. A diamond deburring or shaving element (105) has a shearing edge (107) adjacent the stylus and is also supported for convenient angular adjustement to obtain precise alignement. The entire engraving head is pivotally supported by leaf springs (110) and is raised and lowered by power operated mechanism (116-118). The apparatus also incorporates a scanning head including an improved optical system (130) for precisely and effectively illuminating and detecting the copy to be engraved. Circuitry is also provided for automatically correcting and compensating for unbalance in copy density at repeated lengths on the copy, and the engraver shaft drive is controlled to produce a flat frequency response which passes through the resonant frequency of the oscillating components.
