Role of Sensor in CIM

This post will tell about the role of sensor in computer integrated in manufacturing. Since we know that the computer integrated manufacturing is based on the manufacturing system that has been implemented by the computer based knowledge. Since the sensor is the most linkable to the automation, the sensor is applying their role in manufacturing system through the computer integrated manufacturing. Based on the role of sensor, we can see that the sensor is actually give the most function to the system to make it work as an automation in computer integrated manufacturing.

Role of Sensor in Computer Integrated Manufacturing

The role of sensor systems for computer integrated manufacturing is generally composed of sensing, transformation / conversion signal processing, and decision making, as shown in figure below. The output of the sensor system is either given to the op­erator via a human-machine interface or directly utilized to control the machine. Objectives, requirements, demands, boundary conditions, signal processing, com­munication techniques, and the human-machine interface of the sensor system are described in this section.
