The CNC machine is akin to industrial robots. This project is one of SyncusTech's on-going projects. Due to its technical nature, the Real-Time Operating System (RTOS) should be upgraded to a better improved hardware. Upon our client’s request, we cannot provide further information about the company.
The CNC (Computer Numerical Control) machine installs tools on spindle motors aligned with the X, Y, Z axes and is commonly used to assist cutting materials, which delivers high accuracy in manufacturing. It can be classified as a milling machine for large and hard materials, and a lathe for soft materials. In both cases, control of the servomotor is indispensable. For this function, it’s critical to control the servomotor driver through a CAM (Computer Aided Manufacturing) program installed on the computer main board.
The complexity of products and the need for HSM (High-Speed Machining) increased and the client requested a more convenient UI (User Interface) in a stabilized system environment. For this reason, operating systems and hardware solutions suitable for developing efficient and user-friendly application programs were required. A highly reliable controller was essential for securing stable operations in the long run. Since high-speed operations control positioning in extremely short time intervals, Window OS was reinforced by a separate RTOS (Real-Time Operating System). Sufficient GPIO (General Purpose Input Output) was also prepared.
SOLUTION & IMPLEMENTATION
SyncusTech designed the EMB-80S ODM industrial motherboard, which fulfilled all of the requirements above. Figure 1 is the block diagram that exhibits the configuration of a motion control system based on RTOS, EtherCAT protocol, and I/O terminal blocks. EMB-80S controls servomotors via servo motor drivers and an Ethernet port using the EtherCAT protocol.
CONCLUSION AND BENEFITS
The EMB-80S ODM model provided highly reliable positioning control as well as an improved UI in the form of an X-86 motherboard based on independent IRQ (Interrupt Request), Window OS, and a separate RTOS. With plentiful I/O ports and PCI/PCI-e slots, users were allowed to use the product in a flexible manner.
