To provide a system that collects data from each sensor (airflow, temperature, humidity, atmospheric pressure, illuminance, and air pollution) that measures an environmental factor and can evaluate an environment in a factory in a complex manner. Environmental sensors that measure environmental elements including at least airflow from among the airflow, temperature, humidity, atmospheric pressure, illuminance, and a degree of air pollution, which are the environmental elements in a factory where a machining operation is performed, a display unit that visualizes and displays measurement results of a plurality of environmental elements measured by the environmental sensors, an evaluation and determination unit that evaluates and determines at least one of machine accuracy, work environment, and image accuracy based on the measurement results of the plurality of environmental elements, and a control unit that controls in-factory equipment so that an environment in the factory becomes a preset environment based on results of evaluation and determination by the evaluation and determination unit are included.

In-factory environmental control system

A preventive maintenance system of a machine tool capable of making determination of presence of an abnormality mechanically and automatically, which has conventionally been performed on the basis of the feeling of an operator and detecting an abnormality more accurately in an earlier stage is provided. The preventive maintenance system includes: a vibration detection unit attached to a mechanism of a machine tool to detect vibration; a sound detection unit that detects acoustic waves produced when a work is machined by the machine tool; a servo motor current value detection unit that detects a current value of a servo motor; an abnormality determination unit that compares the vibration, the acoustic waves, and the current value of the servo motor during operation of the machine tool with vibration data, acoustic wave data, and current value data in a normal state set in advance to determine presence of an abnormality in the mechanism of the machine tool; and a detection start/end command setting unit that adds commands for a detection start point and a detection end point of at least one of the vibration, the acoustic waves, and the current value of the servo motor to a machining program.
