Overview of CNC machining process

Although, CNC machining is computer-controlling machining technology. It is computer_aided design (CAD) and computer-aided manufacturing (CAM) using machines.

In CNC machining different materials are specific in different machines of multiple functions. Moreover, different materials are using in CNC machines for specific functions. Material is dependent on the application of CNC machines. Commonly, these materials are aluminum, steel, brass, wood, plastic, foam, copper, titanium, and fiberglass.

The code which is using in the CNC machine is responsible to control the functionality of the machine. The code controls everything from the moment to the cutting head, speed, RPMs, and the part movement of the spindle.

CNC machine has specific parts. These are the main parts of the CNC machine.

Input devices

In CNC machines devices play a significant role to control the programming of machines. These input devices Keep monitoring the magnetic tape reader, and computer  RS 232_C communication.

The machine control unit (MCU)

It is a basic part of the CNC machine because it controls the complete action of the CNC machine. MCU perform various functions such as;

  • Reads codes of instructions, that are given to the machine.
  • Process of decodeof the given codes.
  • MCUreceives signals that are feedback for the position and speed of the drive axis.
  • MCU plays a basic role in controlling complete functionality such as coolant or tool change of spindle on/of.

Machine tool

In a CNC machine, there is a slide table and spindle to control the position and speed,

while working the machine. The slide table is controlling the x-axis and y-axis. The spinner is controlling the z-axis direction while working on the CNC machine.

Driving system

This system of a CNC machine has specific parts to work accurately. Such as Amplifier circuit, drive motors, and Ball leads screw.

Amplifier circuits receive signals from MCU and control the signals to work accurately of drive motors. Through which screw keep the right position of the machine table.

Feedback system

The feedback system of the CNC machine is consists of transducers. Which act as sensors in the machine working. This system is maybe a measuring system. In which position and speed transducers are present. Which monitors the speed and position of cutting tools in the working of the machine. These transducers send signals to the MCU. Both signals of Reference signals and feedback signals are handling differently. To generate the control signals for correcting the speed errors and position in the CNC machining process.

Display unit

Tere is a display unit in CNC machines. Which is a monitor. This monitor plays a specific role to display the programs of working and other useful data of the CNC machine.

The most important process, a CNC machine starts is “designing the part.”

Which is controlling through CAD software. The model gives the necessary dimensions and properties of the final part. This final part is the target of the CNC machine.

Although, CNC machine relies on programmings. Additionally, behind these programmings, there are specific languages for machining. A language is G_code. G_code is responsible for the varying behavior of CNC machines. This G_code controls feed rate speed and coordination of CNC machines. The most interesting thing is G_ code and other languages are installed into computer software only once. After that, there is no need for human operators while the CNC machines working.

The designers produce a model for final products to attach with CAD or computer-aided design software. In this process, basic technical specifications such as geometry and dimensions for producing the final product while the working of CNC machine.

Before the working of the CNC machine, the operator completes machine setup necessities. Such as affixing the workpiece into the machine. He also checks and monitors all basic components of the Machine. The setting of machinery spindles, and other work holding devices by attaching the required tooling.

NC- code is a special simple computer language. CNC machines can easily understand this language and execute it. These codes of NC code, G_code, and ISO code of computer language can control feed speeds, feed rate, coolant, and spindle in the high_tech machinery of CNC machines.

Along with these codes language, CNC machines can read blueprints and sketch manufacturing files for their final product production.
