摘要： In a method of setting heat-resistant alloy cutting conditions used to set cutting conditions under which a heat-resistant alloy is cut with a cutting tool, the cutting tool has a long shaft mounted on a spindle and extended in the axial direction and teeth formed on the shaft. The cutting conditions include a radial direction cutting amount of the cutting tool in the radial direction. When the radial direction cutting amount in which one tooth is constantly in contact with the heat-resistant alloy is given as a smallest radial direction cutting amount and the radial direction cutting amount in which three or more teeth are not in contact with the heat-resistant alloy is given as a largest radial direction cutting amount, a radial direction cutting amount of the cutting tool is set in the range from the smallest radial direction cutting amount to the largest radial direction cutting amount.

摘要： A tool for operating on a workpiece includes a motion actuator and a controller that responsively varies a speed of the motion actuator and an operating speed of a working surface. The controller is configured to respond to a derived force that is a function an applied force exerted by an operator to manageably adjust pressure on the working surface to achieve a rate of work. The controller changes simultaneously both a rate of work on the workpiece and the operating speed of the working surface according to a sensitivity profile. The simultaneous change of rate of work and operating speed is manageable under both acceleration and deceleration by the operator with the applied force. The sensitivity profile expresses a relationship of a monotonically increasing positive slope between the derived force and the operating speed of the working surface within the range.

摘要： A method to control a power tool including the method steps: specifying the rotational speed of the drive at a first value, measuring a first amplitude of a signal, filtering the signal within a frequency range, measuring a second amplitude of the filtered signal, reducing the rotational speed of the drive to a second value if the first amplitude exceeds a first quantity and if the second amplitude exceeds a second quantity, and incrementally increasing the rotational speed of the drive to the first value, whereby each incremental increase of the rotational speed only takes place once the first amplitude remains below the first quantity for a time interval, and the second amplitude remains below the second quantity. A power tool that uses this method, includes: a drive, an acceleration sensor a filter, and a control unit.

摘要： Machining tool comprising a frame in which a drive shaft for a tool is mounted so as to pivot about a rotation axis and to move axially along the rotation axis. The shaft is connected to two rotary motors, namely a first motor connected to a member for meshing with a fluted portion of the shaft in order to drive the shaft in rotation and a second motor connected to a nut engaged with a threaded portion of the shaft in order to move the shaft axially. The motors are connected to at least one control unit designed to control the motors independently of one another, and the first motor and the second motor are coaxial with one another.

摘要： A control system of a machine tool with a rotary type spindle and a feed axis which generates feed motion of the spindle, comprising a current detecting part which detects a current through a spindle motor for driving the spindle, a temperature detecting part which detects a motor temperature, a remaining time estimating part which uses a predetermined maximum allowable temperature and a detected temperature value by the temperature detecting part as the basis to estimate a remaining time until the motor temperature would reach the maximum allowable temperature on the assumption that the detected current value by the current detecting part at the time of the detected temperature value would continue to flow through the spindle motor, and a feed speed changing part which changes speed of the feed motion in accordance with the estimated value of the remaining time.
