A positive feed tool may include a motor, a power supply operably coupled to the motor to power the motor, a gear head and a spindle. The gear head may be operably coupled to the motor to be operated responsive to powering of the motor. The gear head may include a drive assembly and a feed assembly. The spindle may be operably coupled to the gear head to enable the spindle to be selectively driven rotationally and fed axially based on operation of the drive assembly and the feed assembly, respectively. The feed assembly may include an electronically controlled variable feed rate oscillator.

A lens edging system of the present invention includes: an edger configured to perform edging of a spectacle lens using an edging tool; a shape measurement device configured to measure an edging shape of a circumferential edge of the spectacle lens after edging by the edger; a memory part configured to store information regarding a reference shape of the edging tool used by the edger; a shape comparing and judging part configured to compare a measurement result obtained by the shape measurement device and a reference shape of the edging tool specified from the information stored in the memory part, and judge necessity/non-necessity for exchanging the edging tool based on a comparison result; and an information output part configured to output information regarding necessity for exchange when the shape comparing and judging part so judges.

A processing system having a function for appropriately maintaining processing accuracy, without depending on a degree of abrasion of a tool. An unused tool used in a machine tool is captured by using a camera mounted on a robot, so as to obtain a reference image of the tool. Next, an image of the tool is captured after a predetermined number of processing operations carried out. An average amount of tool abrasion per one processing operation is calculated based on the two images, so as to estimate a current amount of tool abrasion. Based on the estimation result and a previously input limit amount of abrasion, the number of remaining possible processing operations of the tool is calculated and output.

A system and method for monitoring and predicting wear of a cutting tool used for machining a workpiece is disclosed. The system includes a cutting tool having a shank and a cutting head. The system also includes a split, modular and wireless wear detection system including one or more sensors mounted to the cutting tool for providing a data signal representative of a physical condition of the system, and a data recording and data transmitting device for recording the data signal from the one or more sensors and for generating and transmitting a data signal to a processor. The processor applies a machine learning data processing technique in real time to monitor and/or predict a condition of various components and/or parameters of the system during a metal cutting operation.

Pressing tools and jaws are described which include communication provisions that enable information concerning the jaws to be used with the press tool, to be transmitted to the tool. The press tool includes provisions that limit or otherwise tailor the output of the tool based on information concerning the jaws.

The method for data exchange during control of processing of a complete tool, which includes a tool holder and a tool, in an integrated/linked processing environment with at least one instrument for mounting the tool into the tool holder and/or a balancing instrument and/or a presetting instrument provides that a superordinate manufacturing planning/control for manufacturing a component communicates processing data for processing the complete tool, in particular a tool list and/or device sheets, to a processing management system. The processing management system then communicates work instructions/data ascertained using the processing data to the instruments of the integrated/linked processing environment.

A method is disclosed for detecting the wear of a cutter in a key-duplicating machine, the cutter being provided with cutting sections to obtain bitting cuts on a key and being put in rotation by an electric motor. The method includes measuring, during at least one cutting cycle carried out by means of the cutter, the values of current and/or voltage absorbed/required by the motor for rotation of cutter and/or motor torque values exerted by the motor. The values thus detected are used to determine if there is wear of the cutting portions of the cutter and/or to quantify the wear of the cutting portions of the cutter.

A system, method and computer program product arranged for managing the operation of a machine and tracing the use of a cutting edge of a cutting tool used in the operation of the machine. The method includes the steps of reading an identification marker of a cutting edge of a cutting tool inserted into the machine, decoding the identification marker to determine a cutting edge information data associated with the cutting edge, obtaining machine operation data associated with the operation of the machine from the machine, and generating a first association data indicative of the cutting edge information data and the machine operation data.

A determining tool for use in determining the shape of the tip end of a machining tool that machines a workpiece held on a table while the machining tool moves relatively to the table includes a bottom surface adapted to be held on the table and a flat slanting surface inclined to the bottom surface and oriented across a direction in which the machining tool moves relatively to the table, the flat slanting surface being adapted to be cut through by the tip end of the machining tool.

Pressing tools and jaws are described which include communication provisions that enable information concerning the jaws to be used with the press tool, to be transmitted to the tool. The press tool includes provisions that limit or otherwise tailor the output of the tool based on information concerning the jaws.
