摘要： In a system which interrupts the infeed signal generated by a CNC (1) machine drive signals are applied to at least an RPM Control Electronics Module (3) to drive the rotation of a cutting tool (10) and the infeed drive motor electronics (7). The frequency is user selectable and the frequency used to eliminate or minimize chip formation is dependent upon the material being drilled, the infeed rate, the RPM of the tool (10), and the diameter and point geometry of the tool (10) so adjustment by the machine operator is required. The interrupted or chopped signal causes the downward motion of the RPM motor (5) to be interrupted in conformance with the frequency generated to cut forming spiral chips.

摘要： A method is described for setting up a computer controlled grinding machine for cylindrically grinding concentric workpiece regions, in which a programme containing data about the workpiece and a programme containing wheelfeed instructions are loaded and the wheelfeed instructions programme is run so as to grind at least one such workpiece regions to final form. The region is gauged and the magnitude and angular position of any unwanted eccentricity introduced by the grinding process, is noted, and the whellfeed programme isntructions or control derived therefrom signals are adjusted so that during subsequent grinding of the said region (or a similar region of a similar workpiece), the wheelfeed is controlled so as to compensate for said measured unwanted eccentricity. The workpiece region is stress relieved before the gauging. After setting up, the grinding machine will eccentrically grind a workpiece region which is to have a cylindrical surface concentric relative to the workpiece primary axis, rather than concentrically grinding the said region, the degree of eccentricity being such that when the cylindrically ground workpiece is stress relieved after grinding, the region will be concentric relative to the workpiece axis. A computer controlled grinding machine is described as are programmes for setting up and grinding.

摘要： In a method for effecting precision laser machining to a work by a laser machining head through additional operation shaft means (8) mounted to a robot body (1) of a multi-joint type laser robot, a required time (A+B) for taking the machining head by rapid feed from an origin point (OR) to a machining start point (E) according to various machining specifications stored in a rewritable storage means and a required time (C) for taking it similarly to the starting point without using rapid feed are calculated and compared with each other by arithmetic means (CPU) provided to a robot controller (10) of the laser robot. Only when the required time (A+B) is shorter than the required time (C), a rapid feed command is given automatically to driving motors (MA, MB) of the additional operation shaft means (8) so that the rapid feed operation of the laser machining head becomes effective to a predetermined laser machining trajectory. In this way, judgement is made automatically and laser machining efficiency can be improved.
