An oil mist management system includes a plurality of machine tools provided in a factory, and an oil mist concentration measuring apparatus for measuring concentration of oil mist in the factory. Further, a data processing apparatus determines whether the concentration of the oil mist is larger than a threshold value, and if the concentration of the oil mist is larger than the threshold value, the data processing apparatus issues a command to decrease machining speed or stop operation of a machine tool that has the lower priority rank among the machine tools.

The invention features, in one aspect, a computerized method for measuring or improving performance of a cutting head of an automated cutting system by evaluating motor control processing of an automated motion control of the cutting head of the automated cutting system. The method includes generating one or more motor outputs for the automated cutting system for any of a cut, a trace, or a motion, the one or more motor outputs corresponding to at least a portion of a set of motor output commands. A characteristic is measured of the one or more motor outputs for the plurality of axes of the automated cutting system. The characteristic is compared with the at least a portion of the set of motor output commands to determine a performance measurement of the automated cutting system.

A machining apparatus includes a multi-joint arm provided with a machining tool for machining a workpiece. A control device of the machining apparatus includes: a storage section for storing NC data indicating a machining region of a workpiece by the machining apparatus; a distance measurement sensor placed on the arm and for measuring a distance between the workpiece and the machining apparatus for each machining surface of the workpiece; and a correction section for correcting the NC data for each of the machining surfaces based on a measurement result by the distance measurement sensor. As a result of this, the machining apparatus can perform the correction of machining data in correspondence to deviation of a machining object with higher accuracy.

A dressing-grinding process for electronically controlled grinding machines for plain or surface grinding of workpieces is described. In order to maintain the effective rough depth during the grinding process, while the roller RPM must be selective and the feed of the dressing roller against the grinding wheel must be continuous, the dressing roller carrier is continuously fed against the grinding wheel carrier in accordance with the functions ##EQU1## wherein is: v.sub.frd (t): feed speed of the dressing roller carrier slide (31) relative to the grinding wheel slidea.sub.ed (t): dressing feed per revolutionn.sub.s (t): grinding wheel revolutionsd.sub.s (t): grinding wheel diametert: current timev.sub.s : grinding wheel circumferential speed; for the described example of a straight grinding wheel it equals the grinding wheel speed v.sub.c. Thus v.sub.c =v.sub.s.y.sub.s (t): vertical coordinate of the wheel centery.sub.x (t): workpiece dimension in y direction.

A method of monitoring the performance of a tool which moves relative to a workpiece through a cycle and controlling the feed rate between the tool and the workpiece includes the steps of dividing the cycle into a plurality of increments, sensing a function of force applied to the tool during the increments, determining a mathematically smoothed function of force for the function of force for each sensed individual increment of the cycle and establishing a reference for the mathematically smoothed function of force for each of the sensed increments. The actual determined sensed mathematically smoothed function of force for a particular increment is compared with the established reference for that particular increment and a first signal is generated if the actual determined mathematically smoothed function of force deviates from the established reference. The feed rate between the tool and workpiece is modified in dependence upon the first signal.
