摘要： Disclosed is an apparatus for automatically detecting the position of the cutting tool in the computerized numerically controlled lathe which is capable of preventing over-load operation of a driving motor by allowing an arm having a touch sensor mounted thereto to be safely stop at a position of detecting the cutting tool while the driving motor stops operating. A bearing housing is fixedly mounted to one side of a housing main body fixed to one side of a headstock. A stopper is fixedly mounted to the bearing housing. A touch sensor is mounted to a front end of the arm and is pivoted by means of a gear assembly driven by receiving a driving force from a driving motor. A camshaft is fixedly installed at a radial outer circumferential surface of the arm. When the arm is rotated and reaches at a proper position, the worm and the worm wheel of the gear assembly are rotated until the camshaft is brought into contact with the stopper. The arm is moved toward the cutting tool and the cutting tool is brought into contact with the touch sensor in accordance with a program that is preprogramedly input into the computerized numerically controlled lathe. At this time, the touch sensor generates a sensing signal and provides the control part with it. After reaching at a position for sensing the position of the front end of the cutting tool, the arm can be fixed at this position due to the operation of an elastic member while the driving motor stops operating.

摘要： A system for transmitting a radio-frequency signal from a contact detecting probe (1), powered by a battery (4), to a remote interface (11), that includes the transmitting, by way of coded serial signals, of messages containing information regarding the state of the probe, the level of charge of its associated battery, and other possible control and identification information. In order to guarantee the repeatability of the delay time that cannot be avoided in the transmission of the change of state of the probe, the bit periods of the single bits that form the message are changed, with respect to a nominal bit period (TN) of the serial signal, on the basis of the delay or the advance at which there occurs the change of state, with respect to a theoretical instant (C0) pre-set within the nominal bit period. Each message comprises a number of bits that represent coded variables, and a start sequence (ST), clearly distinguishable with respect to the coded variables, and enabling the interruption of serial signals the transmission of which is in progress.

摘要： An apparatus for checking thickness dimensions in a semiconductor wafer (1) during grinding operations includes an optical probe (3) which transmits infrared radiations on the surface (2) being machined of the wafer (1), and detects beams that are reflected by said surface, by an opposite surface (2′) of the wafer and/or by surfaces (2″, 2′″) separating different layers in the wafer. The beam of emitted and reflected radiations travels along a path (4) with known and constant discontinuities, in part through the air (15) and in part through a cushion (30) of low flow liquid, which flows with substantially laminar flow. A support and positioning element (7) for the optical probe includes hydraulic ducts (22,25) that generate the liquid cushion. A method for checking the thickness dimensions includes the generation of the liquid cushion at the path along which the beam of emitted and reflected radiations travels.

摘要： In a machine tool (1) comprising a rotating spindle (2) and a vision system (7) for acquiring images of a tool (3) mounted on the spindle, for each value (VC) of an interval (ICN) of preselected rotational speed values centered on a nominal rotational speed value (VN) of the spindle, an image acquisition period (TA) is determined, that is a multiple of the rotational period (TR) of the spindle calculated for that preselected speed value and compatible with the vision system, and, while the spindle is rotating at the nominal rotational speed, a representative couple of tool images that are temporally spaced apart from one another of the image acquisition period is obtained, in order to obtain an estimated speed value (VS), associated to the nominal speed value, by selecting that preselected speed value to which the representative couple of images that are the most similar to each other on the basis of a similarity rule corresponds.

摘要： Bidirectional measuring head (1) comprising: a stationary frame (12), a feeler (2), a kinematic motion assembly (13) which is supported by the stationary frame and carries the feeler to enable the feeler to move along two measuring directions (D1, D2) perpendicular to each other, and at least one position sensor (3a, 3b) that is mounted on the kinematic motion assembly and detects the position of the feeler along at least one measuring direction. The kinematic motion assembly has four columns, each of which runs perpendicular to the two measuring directions: a first column (14) is rigidly linked to the support frame, a second column (15) is adapted to translate along both measuring directions and supports the feeler, a third column (16) and a fourth column (7) each performs a displacement almost exclusively along one of the two measuring directions. The kinematic motion assembly may be a deformable mechanism. The kinematic motion assembly further comprises two balancing elements (60) each of which is hinged to the stationary frame so as to rotate around a rotation axis (33) perpendicular to the measuring directions and comprises one end which is mechanically constrained to the third column or the fourth column.

摘要： A system for numerical control machine tools comprises contact detecting probes, powered by a battery, that transmit radio-frequency signals to associated interfaces. When the probes are not being utilized for checking cycles, they are in a low-energy consumption state, in other words the circuits of the probes are only partially powered. When the need arises, the circuits of a probe are fully powered by the battery, by a radio-frequency activation signal. The procedure for activating a selected probe includes the sending of a generic activation signal from the associated interface, the transmitting of an identification signal from all the probes that have been activated by the generic signal and the sending of a generic confirmation signal from the interface in reply to the identification signal of the selected probe.
