摘要:
A system for automatic chip breaking used in a cutting machine is illustrated, wherein the cutting machine has a cutter and a spindle actuator. According to control information, the spindle actuator controls the cutter to move along with a first axis to cut a workpiece, and the chips are produced. The system for automatic chip breaking includes a signal collection device, a controller, and an actuator. The signal collection device electrically coupled to the cutting machine collects the control information. The controller electrically coupled to the signal capturing device triggers a control signal according to the control information. The actuator installed between the spindle actuator and the cutter is electrically coupled to the controller, and controls the cutter to vibrate along with a second axis according to the control signal, wherein the second axis and the first axis have a specific angle.

A feeder for rods into a lathe by a motorized thruster for sliding and pushing a rod along a guide towards a processing lathe until the rod is taken by the lathe. An automatic control device actuates the thruster to advance according to a first thrust value and a sensor detects the movement of the thruster. If the sensor detects a minimum movement or no movement at all a thrust increase is commanded up to a predetermined maximum value. If the thruster does not move at all, this indicates jamming.

A sensor and monitoring system for performing work upon an inner diameter of a machined workpiece, such as a pipe turned by a lathe, with the work being viewed and/or recorded remotely. The system includes a sensing device having an elongated rod, at least one sensor mounted to a first end of the rod, and a power supply and a transceiver mounted to a second end of the rod, the sensor being positioned within the bore of the workpiece for performing work upon the inner diameter and the transceiver and power supply positioned external to the bore. A controller device is wirelessly connected to the transceiver for wirelessly receiving and sending communication signals to and from the sensor via the transceiver. The sensor may of various types, such as a linear touch probe, a distance sensing laser, a temperature, vibration, gas, noise, or ultrasonic sensor, or a camera.

The present invention provides methods and systems for chip breaking, controlling cutting tool wear, and the like in turning, boring, and other applications, including: engaging a workpiece with a cutting tool in a feed direction along a toolpath, superimposing an oscillation in the feed direction on the toolpath, and dynamically or non-dynamically varying the oscillation superimposed in the feed direction on the toolpath such that interrupted cuts and chips of a predetermined length or less are produced. These systems take full advantage of computer numerical control (CNC) methodologies.

A toolholder with a controllable critical angle, such as a lead, trailing, rake or clearance angles, includes a tool spindle for retaining the toolholder in a tool rest of a machine tool. The machine tool includes at least one linear axis, for example, three mutually perpendicular axes, a rotary axis and a rotation axis. The rotary axis and/or rotation axis is controllable to move to a specified position in synchronization with a movement of one of the linear axes. An adaptor supports a cutting tool that is retained in the adaptor by a clamp. The cutting tool defines a critical angle, such as a lead angle, a trailing angle, a rake angle and a flank clearance angle, wherein the critical angle is corrected as a vector of movement of at least one of the linear axis is changed. In addition, the cutting tool can be positioned on opposite side of a centerline of rotation of the workpiece to effectively double the life of the cutting tool. A method of controlling a toolholder is also disclosed.

In a method for cutting freeform surfaces, a workpiece is cut by a cutting tool such that a desired freeform surface may be achieved, the cutting tool for cutting purposes being moved along at least one defined cutting path relative to the workpiece. A cutting tool is used, the tool head of which has a greater radius than a tool shank of the cutting tool.

An ultra-precision machining system includes a worktable, a first support device, a second support device, a rotating shaft, a cutting tool, a detector and a controller. The first support device is fixed on the worktable. The second support device is movably mounted on the worktable. The rotating shaft is rotatably connected to the first support device. The cutting tool is mounted on the second support device and is movable relative to the second support device along a vertical direction. The detector is fixedly connected to the first support device above the rotating shaft for detecting an axial deviation of the rotating shaft. The controller is configured for calculating the axial deviation of the rotating shaft and adjusting the position of the cutting tool relative to the rotating shaft to counteract the calculated axial deviation of the rotating shaft.

With the use of a tool (41), first cutting is applied to a work (W), and then second cutting is applied to the work (W) while the tool (41) is transferred in an X-axis direction. Then, an amount of deviation dy between the cutting edge height of the tool (41) and the center line of the work (W) is calculated based on a first diameter value (D1) and second diameter value (D2) measured after the first cutting and second cutting are applied, and the travel distance of the tool (41) between the first cutting and the second cutting. Machining to the work (W) is resumed after the amount of deviation is corrected.
