摘要： An apparatus for sensing a position of a cutting tool in a computer numerical controlled machine tool is provided including an arm supporting and moving a sensor that cooperates with the cutting tool. Also provided is a housing including a gear assembly and a driving motor for moving the arm, and a stopper for defining an operating position of the arm. The driving motor supplies rotation force to the gear assembly so as to pivot the arm against the stopper and then apply force to an elastic member. When the driving motor is stopped, the elastic member applies a force, through the gear assembly, urging the arm against the stopper in the operating position.

摘要： A method of truing cutting tools of the type comprising a plurality of stick-type cutting blades releasably secured in a cutter head, the cutting blades having a cutting edge and a cutting side relief surface oriented at a predetermined relief angle. The method comprises mounting a cutting tool to the spindle of a truing apparatus having a cutting tool spindle and a measuring probe with the probe capable of being moved along a first direction defining probe offset travel and along a second direction defining in/out feed motion of the probe. The cutting side relief surface of the cutting blade is positioned with respect to the probe whereby the cutting side relief surface is substantially parallel to the direction of probe offset travel. The cutting side surface of the cutting blade is probed and the position reading is recorded. The recorded position is compared with a predetermined position, and (a) if the recorded position is within a pre-set tolerance range of the predetermined position, the cutting tool is indexed to another cutting blade, or, (b) if the recorded position is outside of a pre-set tolerance range of the predetermined position, the position of the cutting blade in said cutter head is axially adjusted by an amount to reposition the cutting side within the pre-set tolerance range.

摘要： The single point machining head includes a probe that is removably mounted on a carriage that moves radially relative to a central axis of the machining head. A system controller moves the carriage in a radial direction while the machining head is fed in a vertical direction so that the probe contacts the surface of a workpiece. Each point of contact on the workpiece becomes a datapoint including the radial position and the vertical position when contact occurred. The surface of the workpiece is scanned with the probe and a profile is generated using the points of contact. A system controller calculates a difference between the measured profile and a desired profile to be machined to determine the amount of material to remove.

摘要： The invention relates to improvements in the multiple spindle rotary indexing machine tool systems of the prior art. Traditionally, such machine tool systems include a base and an upstanding vertical column which houses a plurality of machining stations each equipped with two-axis tool slides. In addition, the base supports a rotatable worktable, which carries a number of work-holding spindles. As the worktable rotates, these spindles are indexed through successive machining stations where a variety of operations are performed. In accordance with the invention, a spindle position measurement unit is provided to dynamically measure the exact location of each spindle indexed to position at a modified machining station. A computerized numerical control system calculates spindle position errors based on the position information provided by the measurement unit and offsets tool slide position commands to compensate for those errors. As a result, the control unit compensates for both fixed and variable spindle position variations, thus improving the machining tolerances of the machine tool apparatus. In accordance with another aspect of the invention, a high accuracy finishing station is provided which includes spindle position variation measurement and compensation in combination with an independent X and Y axis tool slide positioning system. The tool slide positioning system is responsive to CNC commands for speed control and position offset due to spindle errors.

摘要： A multi-purpose probe module 82, comprising both a touch-trigger type contact probe 84 and a non-contact type probe 86, is used in method and apparatus for monitoring and adjusting the accuracy of a computer-controlled machine for manufacturing precision bevel and hypoid gears. The probe module is mounted on the machine's tool support and is used in conjunction with locating points positioned on the machine's work support to monitor and recalibrate the relative positions of the tool and work supports. The probe module is also used to monitor the flanks of the gear-shaped workpieces (a) for initial stock division, (b) for pre-machining accuracy, (c) for first-piece testing, (d) for in-process accuracy, and (e) for post-machining accuracy. The same probe module is used in combination with a sacrificial test wafer mounted on the work support for adjusting the position of the machine's cup-shaped grinding wheel following each dressing of the latter's working surfaces.

摘要： In a grinding machine a measurement arrangement is provided for the monitoring of the processing of a work piece, especially to make tools. The measuring arrangement uses, preferably, combined transmitted-light and incident-light based techniques so that both the edges and surfaces and depressions on the work piece are detected precisely. The automatic measurements makes it possible to automatically adjust the process parameters for the grinding process so that changes due to temperature drift, mechanical imprecisions of the mechanical system of the grinding machine or wear on the grinding disks are automatically compensated. This makes possible production of relatively large batches within very close tolerances and with high precision.

摘要： A method for measuring the contour of a machined part with a contour gage apparatus, having a probe assembly including a probe tip for providing a measure of linear displacement of the tip on the surface of the part. The contour gage apparatus may be moved into and out of position for measuring the part while the part is still carried on the machining apparatus. Relative positions between the part and the probe tip may be changed, and a scanning operation is performed on the machined part by sweeping the part with the probe tip, whereby data points representing linear positions of the probe tip at prescribed rotation intervals in the position changes between the part and the probe tip are recorded. The method further allows real-time adjustment of the apparatus machining the part, including real-time adjustment of the machining apparatus in response to wear of the tool that occurs during machining.

摘要： A system and method are disclosed for automatically machining a work piece to precise selectively determined dimensions under computer numerical control. A movable probe is calibrated against position reference surfaces and is then used to calibrate the position of a fixed probe. The latter serves as a position reference for calibrating the cutting edge of one or more cutting tools. All calibrations are performed under closed loop control. Appropriate tool position offsets are automatically determined from deviations between the programmed and the actual probe and tool positions and are entered into numerical control means to modify the programmed machining operation. After machining has been initiated, probing of the work piece occurs at least once before the final cut is taken and the appropriate tool position offsets are determined and entered to assure that the dimensions of the finished surface will conform to the desired selectively determined dimensions. Any dimensional deviations which are shown to exist upon probing of the finished surface, are indicated together with the allowable machining tolerances for each dimension.
