CNC is automatic mechanical, its can work with input program by computer and assign operation follow from program. Many languages use with metal machine that have complex and need high precise even as able molding or not.
CNC machine can work by control system of machine. The system must be use language command that control system able to understands, what should to do. Therefore, must necessary input program to control system through keyboard. When the control system read program, it’s bring to control the machine work by depend on Feed Motor for moving sled throne. Then the control system read program and change code program to electric signal for control operate motor. But, signal from control system have little power, it’s can’t spin drive motor to operate. In that way, must sent this signal inside amplify section of Drive Amplifier and forward signal to motor. Assign axis line for moving follow by command. Speed and distance of sled throne must assign the control system to know because the control system of CNC machine can’t see that. Different from technician, they use their eyes for look the position of sharp intersect invention. They know how far to moving sled throne. So, must design equipment or instrument that able specify position of sled throne for control system to know? This equipment called “Measuring System” is composed of Liner Scale. In ambulatory of machine have Liner Scale equal axis line. Perform sent electric signal in proportion with distance of sled throne that back to control system. Cause to the control system know how far the sled throne moving. CNC have very high precise appropriate for invention that need fixed size and all inventions regular quality. For use program in order the machine work have little damage and can work 24 hours but should have control man check the CNC machine but not all the time. The CNC machine has high speed for produce a lot of products able to estimate and plan to produce precisely. Cause to know time to work for appoint customer on time. Appropriate to produce prototype or complex invention.
In conclusion, CNC machine is the development from basic machine by bring computer system to control motor. When motor drive cause to moving in several directions depend on order for increase ability of machine to produce complex and most precise invention. CNC machine can produce with high quality and fast. So, it’s good in industries that need high quantity or high exactitude.
