摘要： A system for establishing data defining a path for machining tool such as a three-axes milling machine tool. The machining tool path is established within a three-dimensional rectangular coordinate system which corresponds to a machine coordinate system for numerical control. The tool path is established along a first coordinate axis. The tool path is shifted to an adjacent path along the first coordinate axis in a second axis direction. The shifting pitch of the path corresponds to the interval of said path along the first the coordinate axis. The tool is shifted in third axis direction during travel along the path defined in the first and second axis direction.

摘要： In order to permit manual operation under a condition where the axial direction of a tool and the direction of a hole to be machined in a workpiece are held in agreement, the tool of a radius .gamma. is rotated by .theta. in the vertical rotational direction and by .rho. in the horizontal rotational direction in a orthogonal coordinate system and in a spherical coordinate system the origins of which coincide with the center of rotation of the tool. Upon doing so, in the orthogonal coordinates, the position of the front end of the tool becomes X.sub.0 =.gamma. sin .theta..multidot.cos .rho., Y.sub.0 =.gamma. sin .theta..multidot.sin .rho. and Z.sub.0 =.gamma. cos .theta.. Therefore, a train of pulses (Hp) from a manual pulse generator are distributed as X-, Y- and Z-axial components in the proportion to the above values by a manual pulse distribution circuit, and motors for the respective axes are driven through servo circuits by the pulses.

摘要： An apparatus for forming composite, fiber/resin components with fibrous, resin-impregnated tape is disclosed. The apparatus employs a gantry for positioning a tape dispensing head assembly over a mold structure, which defines a mold surface of planar or contoured configuration. A control system is employed having sensing devices for generating signals indicative of relative positions of components of the apparatus in several axes of permissible movement, and tape application is effected by means of major and secondary command inputs to appropriate servomotor devices. Primary and initial movement is controlled in accordance with a sequence command program in cooperation with a resident program in a digital computer, and a second, adaptive control system is alternatively employed for enabling the tape dispensing head to follow vertical contours of the mold surface during X-Y movement across the surface.

摘要： Ordinarily, an interpolator (102) executes pulse calculations on the basis of a movement command from a command tape (101), to generate the respective distributed pulses XP, YP, ZP, BP and CP of cartesian coordinate axes and spherical coordinate axes, and these pulses drive corresponding servomotors (113)-(117) through servo circuits (108)-(112). In order to keep the relative position between the nose of a tool and a workpiece unchanged in a manual operation, a tool holder is positioned in the cartesian coordinate system, whereupon manual pulses in the B-axial or C-axial direction are generated by a manual pulse generator (103). Then, the distributed pulses BP and CP are generated through the interpolator (102) and rotate the servomotors (116) and (117). The distributed pulses are simultaneously impressed on a compensation circuit (104), which calculates the compensation pulses XHP, YHP and ZHP so as to drive the servomotors with pulses obtained by adding the compensation pulses to the distributed pulses.

摘要： An improved drilling device for drilling normal holes in a workpiece surface is carried and positioned by an automatic control arm. The improved drilling device includes a compliant drill head generally comprising a drill housing and a pressure foot. The pressure foot for contacting the workpiece surface is connected to the drill housing at a universally swiveling joint. The drill housing encloses a drill drive means that advances and rotates a drill tool about a drill axis. Both the pressure foot and the drill housing have axial chambers and holes for permitting the drill tool to advance to the workpiece surface. Linear gauges mounted to the drill housing probe the orientation of the pressure foot relative to the drill housing. The linear gauges provide data to the automatic control arm so that when the pressure foot contacts a portion of the workpiece surface that is not normal to the drill axis and the pressure foot swivels relative to the drill housing as the pressure foot orients normal to the workpiece surface, the control arm can realign the drill housing with the pressure foot so that the drill axis is normal to the work piece surface and so that the drill tool can be advanced and rotated toward and through the workpiece surface there by drilling a normal hole in the workpiece surface.

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 computer-based system and method is provided for positioning a cutter tool to an edge of a solid model in a computer aided manufacturing environment. A shortest distance and direction required to position the machine tool cutter to the edge of the solid model is determined. Edges are defined as three dimensional space curves. The machine tool cutter is defined as a convex envelope. Using the space curve definition, the cutter location, and the center axis of rotation for the cutter, computations are executed to determine a directional vector and distance such that moving the cutter along the vector for the prescribed distance will cause it to be in contact with the curve. Adjustments are available which cause the cutter to travel to offsets from the curve, including aligning the front of the cutter to the curve, the end of the cutter on the curve, or the back of the cutter past the curve.

摘要： A digitizing control apparatus successively receives positional data and produces NC data while tracing the shape of a model. The digitizing control apparatus has a tracer head (3) having first and second non-contact-type distance detectors (30a, 30b) for independently measuring distances up to the surface of the model, the first and second non-contact-type distance detectors being positioned to travel parallel to a feed direction. A sampling circuit (16) samples measured values from the first and second distance detectors (30a, 30b) at predetermined times. A memory (13) stores a previously sampled measured value from the non-contact-type distance detector (30a) and a previously sampled measured value from the non-contact-type distance detector (30b). Data in a normal direction of the model surface (4) are determined based on at least three of the previously sampled measured values, a presently sampled measured value from the non-contact-type distance detector (30a), and a presently sampled measured value from the non-contact-type distance detector (30b). Therefore, the data in the normal direction can be obtained at high speed. The data in the normal direction thus determined are used in the determination of a tool offset, for example.

摘要： The coordinate values (X, Y, Z) for the position of the front end of a tool and the vector (I, J, K) of the axial direction of the tool are read in from a command tape by a tape reader. Using these values and a tool length l set by a dial or the like, a movement data calculation circuit calculates the orthogonal coordinate values (x, y, z) of the position Q of the center of rotation of the tool and spherical coordinate values (b, c) indicative of the position of the rotational angle of the tool. After these coordinate values are converted into pulses for moving the tool in the respective axial directions by a pulse distribution circuit, servomotors are driven by the pulse signals and through servo circuits so as to move the tool or a table to a desired machining position.
