Document Type and Number:
Japanese Patent JPH05500190
Kind Code:
A
Abstract:
A metalworking fluid central system through which aqueous cutting fluid recirculates through a plurality of machine tools is provided with an in-line fluid condition monitor which produces real-time fluid composition data for use in controlling the condition of the fluid. Four sensors simultaneously measure temperature, pH, dissolved oxygen and conductivity at hourly intervals and the data is stored in a computer module linked to the monitor. A plurality of diversely located plants are similarly equipped. A computer at a remotely located central monitoring facility selectively connects to the computer modules at the various plants through modems and a telephone system to collect the data daily. The data is analyzed at the central facility and dimensions are made manually and automatically to add components to the fluid at the respective plants or to take other corrective action. Commands and recommendations are communicated to the computer modules at the respective plants where they are manually and automatically implemented by the operation of valves, pumps or other devices or methods to modify the make-up of the fluid in the central system.
