  • Patent number: 9921567
    Abstract: Improvements in a high speed smooth tool path is presented where the high speed smooth tool path to be used for primarily finishing for finishing any type of walls (negative/positive drafted) for any given bounded region be it 3, 4, 5, . . . n sided shape. The tool path incorporates a combined strategy for finishing the walls while removing any excess material leftover from a previous larger diameter cutter. This tool-motion can be utilized for roughing the regions by approximating the walls by offsetting the regions inwards. The finished boundaries are offset inwards and then cut using these methods. This is optimized as opposed to moving the cutter at a consistent speed in the cutting path. This is performed to eliminate the wasted tool-motion to the maximum extent. This technique is implemented for roughing any closed or open bounded areas regardless of the walls being straight, drafted (negative/positive or both).

  • Patent number: 9636780
    Abstract: Two substrate pieces are welded together with a focused laser beam. One of the pieces is transparent in the wave length of the laser beam. The two pieces are pressed together so the tops of the roughness of the joining surfaces become level and both a uniform and pocket like air layer is removed from between the surfaces. The focal point of the laser beam is focused in the common boundary surface of the substrate pieces and the pieces are set to movement in relation to the laser beam so that the focal point advances in the boundary surface according to the shape and length of the weld. The energy of the focal point melts the material of the two pieces at the same time. When the melts mix and harden, a weld is formed that joins the pieces hermetically and goes round the third piece(s) isolating it hermetically.

  • Publication number: 20150066195
    Abstract: A method for positioning a tool (3) mounted on a spindle (2) of a numerical control machine tool in the visual field (20) of a visual system (7) for measuring the tool, includes a step of moving (35) the rotating spindle along an axis (Z) from a reference position (Z0) towards a target position (Zobj) defined in the visual field, and a step of acquiring images of the visual field. The stop of the spindle movement along the axis is controlled as soon as an acquired image (IM1) reveals (36) that a determined portion (13) of the tool, for instance a tip, has entered the visual field. When the stop is controlled (37), an instant position (Z1) of the spindle is acquired (38) and a distance (POS) between the tip of the tool and the target position is measured (39). On the basis of such instant position and distance, a final position (Z2) is calculated (40), and the spindle is brought (42) to such final position.

  • Publication number: 20150039122
    Abstract: Optimized positioning paths for multi-axis CNC machining can be generated based on the machine tool kinematics, machine axes travel limits, machine axis velocity and acceleration limits, and machine positioning methodologies. Machine axes travel limits and machine positioning methodologies are incorporated in order to ensure that the developed positioning paths do not violate machine axes travel limitations. Multi-axis positioning paths are developed to avoid collisions with dynamically changing in-process stock and other surroundings, including fixtures and both moving and non-moving components of the machine. Positioning tool path customizations give the user the flexibility to apply safety based constraints to the automatically generated tool paths. The disclosed automatic positioning path planning and optimization methods are used to develop a process for part manufacturing using CNC machining in order to reduce the manufacturing cycle time.

  • Patent number: 8938316
    Abstract: In connection with a machining program used in machining a workpiece by means of a machine tool controlled by a numerical controller, interpolation data, a command position point sequence, and a servo position point sequence for each processing period are determined by simulation by designating speed data for giving a machining speed and precision data for giving a machining precision. A predicted machining time for workpiece machining is determined based on the determined interpolation data, and a predicted machining error for workpiece machining is determined based on the determined command and servo position point sequences. Further, the precision data and the speed data are determined for the shortest predicted machining time within a preset machining error tolerance, based on a plurality of predicted machining times and a plurality of predicted machining errors.

  • Patent number: 8924004
    Abstract: A numerical controller calculates the distance (rotation radius) between the rotation center axis of a rotary axis and a control target point using the machine conditions (including the axis structure and tool length) of a machine tool having a rotary axis and the coordinate values of the respective axes of the machine tool. Then, the preset positioning completion widths of the respective axes are compensated by the calculated rotation radius and a positioning completion check of the rotary axis is carried out using the compensated positioning completion widths.

  • Patent number: 8868228
    Abstract: When a numerical controller executes a tool-center-point control in which a path of a tool center point with respect to a workpiece is instructed, and the workpiece is machined along the instructed path based on a speed instruction, the numerical controller sets the speed instruction so that the speed instruction is a synthesis speed with respect to a synthesis distance of a relative moving distance between the workpiece and a tool center point and a tool-direction changing distance due to a relative change in a tool direction with respect to the workpiece by a rotary axis. The numerical controller interpolates a position of a linear axis and a position of a rotary axis by the tool-center-point control according to the synthesis speed and drives the linear axis and the rotary axis to the position of the linear axis and the position of the rotary axis created by the interpolation.

  • Patent number: RE45391
    Abstract: A drilling machine drills at a multiplicity of target locations on a component. Two robots, calibrated with calibration data, move the component in a 6-D coordinate system. A metrology system ascertains the position of the component relative to the drilling machine. The movement of the robots is effected by commands generated by off-line programming. The component is moved relative to the drilling machine to a target position, ready for drilling, by a closed-loop process in which the differences in position between the expected position (the target position) and the actual position (as viewed by the metrology system) are corrected.
