Machine Control Unit

The machine control unit (MCU) is like the backbone of CNC systems. Following six functions are being completed by MCU:

• Read coded instructions
• Decode coded instructions
• Implement interpolations to produced axis motion commands
• Feed axis motion commands to amplifier circuits to drive axis mechanisms
• Receive the feedback signals of position and speed for each drive axis
• Implement auxiliary control functions such as coolant ON/OFF, spindle ON/OFF, and tool change
