摘要： In a system which interrupts the infeed signal generated by a CNC machine drive signals are applied to at least an RPM Control Electronics Module to drive the rotation of a cutting tool and the infeed drive motor electronics. A solid state relay intercepts the infeed signal and is driven into an on off state by a Variable Frequency Generator. This causes the solid state relay to enter the on off state in response to the input frequency and interrupts the infeed signal applied to the infeed motor electronics in synchronization with the frequency generated. The frequency is user selectable and the frequency used to eliminate or minimize chip formation is dependant upon the material being drilled, the infeed rate, the RPM of the tool, and the diameter and point geometry of the tool so adjustment by the machine operator is required. This permits the user to vary the specific frequency to select a frequency which is suitable for elimination of spirals in a given set of circumstances. The interrupted or chopped infeed signal causes the downward motion of the RPM motor to be interrupted in conformance with the frequency generated. Since the infeed rate of the cutter tool is also momentarily interrupted the tool penetration is interrupted. This process causes the cutting tool head to rotate without penetration and cuts the forming spiral chip.
摘要翻译：在中断CNC机床驱动信号产生的进给信号的系统中，信号被施加到至少一个RPM控制电子模块，以驱动切割工具和进给驱动电机的旋转。固态继电器拦截进给信号，并由变频发电机驱动进入导通状态。这导致固态继电器响应于输入频率而进入导通状态，并且与产生的频率同步地中断施加到电动机电子装置的馈入信号。频率是用户选择的，用于消除或最小化切屑形成的频率取决于所钻的材料，进刀速度，刀具的RPM，以及刀具的直径和点几何形状，因此需要机床操作员的调整。这允许用户改变特定频率以在给定的情况下选择适合于消除螺旋的频率。中断或切断的进给信号导致RPM马达的向下运动中断，以符合所产生的频率。由于刀具的进刀速度也被暂时中断，刀具穿透被中断。该过程使得切割工具头旋转而不穿透并切割成形螺旋形芯片。

摘要： A tool head for the precision cutting of a surface of a rotating workpiece has a cutting tool which is movable in opposition to the force of a restoring spring from an initial position into an operating position with respect to the workpiece via an actuating drive. The actuating drive is formed by a translatorily movable driving element and a transfer element which converts the driving movement into an adjusting movement. The driving element used for adjusting the cutting tool from the initial position to a machining position is formed by an expansion bar actuated by magnetostrictive principles.

摘要： An apparatus for controlling a tapping-drilling machine is disclosed in which holes can be formed by means of drilling tools, and threads can be formed by means of tapping tools. A worm is elongately formed on a spindle, and a worm wheel which is meshed with the worm is secured by a lateral shaft. At the leading end of the lateral shaft, there is installed a brake. In the preferred embodiment of the present invention, the electronic type brake is employed, and the electric current flowing through this brake is adjusted, so that the velocity of the vertical movement of the spindle sleeve (which is defined to be the ratio of the vertical moving distance to the revolutions of the spindle) can be automatically adjusted. For this purpose, an overall supervising controller in the form of a micro-controller is provided to receive sensed data from a spindle revolution sensing section, a revolution deviation (difference) sensing section, a spindle sleeve position sensing section and a manipulation switching section so as to output computed control data to an electronic brake control section, a motor forward/reverse driving section and an operation and alarming display section. Thus during a tapping or drilling operation, the micro-controller controls the pre-requisite functions for the automation of the tapping or drilling operation such as a step feeding function, a chip breaking function, a dual feeding function, a dwelling function, an overload protecting function, and the motor forward/reverse driving function.
