摘要： A tool monitoring system monitors the condition of an electrically powered tool performing a cyclical operation. The tool monitoring system operates generally in two modes: learning mode and monitor mode. In learning mode, the tool monitoring system gathers statistical data on the power consumption of tools of the selected tool type during learning cycles. A power threshold is generated based upon the statistical data. The tool monitoring system then counts the number of crossings by each of the learning cycles of the power threshold and generates statistical data regarding the number of crossings. Preferably, the mathematical operation of wavelet packet transform is used to calculate the power threshold. Feature wavelet packets of the power consumption signal of the tool are calculated. The power consumption signal is then reconstructed from the feature wavelet packets and used to determine the power threshold. In monitor mode, the tool monitoring system counts the number of crossings of the power threshold by the power consumption signal of a tool in operation. The tool monitoring system identifies a worn tool when the number of crossings increases to a certain number relative to the crossings by the learning cycles.

摘要： In order to detect an operating state of equipment, when a plate material reaches a support part, a press machine outputs a start signal to move a press part downward. An input receiver receives input of the start signal. An operating detector detects that the press machine is in an operating state. When the press machine moves the press part upward, and shaping of the plate material ends, the press machine outputs a standby signal. The input receiver receives input of the standby signal. The detector detects that the press machine is in a standby state. When the plate material is again conveyed onto a roller conveyer from the support part, the press machine outputs a stop signal. The input receiver receives input of the stop signal. The detector detects that the press machine is in a stop state.

摘要： A machine with automatic feed speed control comprising, a work-piece advancing device for advancing a work-piece in a feed path at a feed speed, a work-piece tooling device having a tool member movable in the feed path with a portion engageably with the work-piece for tooling the work-piece and for receiving a load from the advancing work-piece through the action of the work-piece advancing device. The load is proportional to the size of the portion of the tool member engaged with the work-piece. A speed controller is connected to the work-piece advancing device for increasing and decreasing the speed thereof and thereby increasing and decreasing the feed speed of the work-piece. Work-piece sensors are provided in the feed path engageably with the work-piece for sensing the size of the portion of the tool member which will become engaged with the work-piece, which size corresponds to a maximum load on the work-piece tooling device. A transducer is connected between the work-piece advancing and tooling devices and connected to the sensors for reducing the speed of the work-piece advancing device when the maximum load set by the sensors is exceeded. Thereby, the machine always operates at full feed speed, which is reduced only when the maximum load of the tooling device is exceeded.

摘要： Grinding method and apparatus in which metal removal rate of workpieces is controlled to predetermined values at least during fine grinding. The metal removal is measured out by an in-process size detector, which measures the workpiece diameter under grinding, and is compared with one of the predetermined values directly or indirectly after being converted into metal removal-to-time rate. The deviation of metal removal from the predetermined value effects to control the infeed movement of an infeed table which displaces the grinding wheel to infeed relative to the workpiece.

摘要： A grinding wheel has its feedrate controlled in accordance with a force exerted on the grinding wheel when it is in cutting engagement with the workpiece. The force is compared with a reference force, and the difference is utilized to select the feedrate of the grinding wheel into the workpiece. When the workpiece is reduced by the grinding wheel to a predetermined size, the reference force is changed.
