Abstract: In a competitive manufacturing environment, machining high precision components with narrow dimensional variations is vital. Evidences show that the dimensional variations exist not only in a single point, but throughout the surface of the component. Several researchers are working in this field to reduce these dimensional variations in the component. In this paper, a new technology called portable intelligent system (PIS) is introduced to reduce the component's dimensional variations in CNC milling machine in real-time. The PIS consists of various components, which includes both hardware and software. This system acts as an auxiliary device for CNC machine tools. This device has its own built-in controller, which has intelligent to monitor and control the dimensional variations to zero. This device is designed such a way that it can be mounted on any existing CNC vertical milling machine. A comparison study between conventional machining and precision machining using PIS was carried out with 20 samples and their results show positive outcomes.
