Single Board CNC Controller
June 1, 2015
The Centroid Oak board is a complete CNC control contained in one printed circuit board.
According to the company, Oak based CNC systems can take advantage of widely available price competitive AC brushless motors and drives. Designed for both new machinery installations and retrofit upgrade applications, the 12" x 8" Oak board is compact and contains an integrated DSP motion controller (MPU11), a CNC programmable logic controller (PLC) with nine fused relay outputs, along with 16 inputs, plug and play cable connections for a variety of AC brushless servo drives, operator control panel connection, MPG (operator handwheel) connection, digitizing and tool touch off probe connection.
Preconfigured PLC programs and operator control panels for common CNC machine tools are standard and customizable for specialty CNC machines. The new Oak CNC controller communicates with the Windows based (7 or 8) CNC PC via Ethernet connection. This allows the Oak board to be mounted close to the servo drives, eliminating long runs of encoder cable - decreasing cost while increasing reliability, according to the company.
On a recent retrofit application on a 1999 MSC Vectrax CNC mill, the single Oak board replaced five different printed circuit boards from the original control, along with a lot of cabling, wires and power supplies. The existing servo drives and servo motors were retained and the new Oak system provided a performance boost in several areas. Smoother, faster machine tool motion was achieved while providing the owner with a modern, easy-to-use CNC interface and straightforward windows networking and file transfer. All of the older G-code and Intercon (Centroid's conversational programming software) programs were retained and reused. This machine is now ready for another 15 years of service.
Oak can be paired with a Centroid M400 CNC operators console or with a user supplied standard VGA LCD (any size) and USB keyboard and mouse. The new M400 console now features as standard equipment a 15" touchscreen color LCD display. The console is also thinner and lighter than previous versions. Worldwide on-site CNC installation by certified Centroid installers are available, along with DIY CNC control kits. In addition to retrofit upgrades, new CNC machine tools are available with the Oak CNC controller.
