In a previous blog we discussed what is CNC? What are the advantages and disadvantages of CNC and where do we use CNC? Now in this blog we will discuss some applications of CNC machining tools . We will also discuss what is DNC( Distribution numerical control)?. Did You know each tool in a CNC machine performs a specific task? The word NC came into existence in seventeen century when microprocessors and microcomputers replaced integrated circuit IC based control used for NC machines. NC was proposed in the late 1940s by John Parsons to generate smooth profiles on workpieces by guiding a milling cutter in a curvilinear motion.
About
In the past, it was initially used for metal working machines: mills, drills, boring machines, punch presses, etc. but has now expanded to robotics, grinders, welding machinery, EDM, flame cutters, and inspection equipment. In contrast, DNC is a Direct Numerical Control system where several NC machines are operated at the same time by using a mainframe computer.
Let's discuss some applications of CNC,
Application of CNC Machine Tools
Machines controlled by CNC can be divided into the following categories:
CNC mills and machining centres
CNC lathes and turning centres
CNC electrical discharge machining (EDM)
CNC grinding machines
CNC cutting machines (laser, plasma, electron, or flame)
CNC fabrication machines (sheet metal punch press, bending machine)
CNC welding machines
CNC Vertical Machining Centre
A CNC vertical machining centre is a type of Computer Numerical Control VMC with vertically oriented spindles and automatic tool changers that approach a workpiece mounted on a worktable from above.
CNC Turning Machining Centre
CNC milling/turning machines accomplish a number of tasks all at once to create complicated workpieces.
CNC Laser Cutting Machine
A CNC laser cutter is a piece of equipment that employs computer numerical control (CNC) technology to mark, cut, or engrave materials to produce certain shapes.
CNC EDM Machine
EDM spark erosion machines that use high-frequency power between positive and negative anodes are referred to as CNC Die Sinking/Sinker EDM Machines, CNC Die Sinking EDM Machines, and CNC Spark Erosion Machines..
CNC Hydraulic Plate Punching And Marking Machine
A specialised CNC machine is used in the steel tower business to punch and mark steel plates. Other industries also use it to punch and mark steel plates.
Now let's discuss the DNC?
Direct Numerical Control (DNC)
As I previously mentioned, the DNC is a Direct Numerical Control system where several NC machines are operated at the same time by using a mainframe computer.The computer's primary functions include creating, editing, and downloading part programmes to the NC machine. Machine tools controllers have limited memory and a part program may contain a few thousands of blocks. As a result, the software is transferred to the machine, one block at a time, from a different computer.
Distributed Numerical Control (DNC)
The abbreviation for Direct Numerical Control also applies to Distributed Numerical Control (DNC). After the introduction of CNC, the machine tools have had the capability of storing large amounts of information. Therefore, there has been no need to have a drip feed information system, like, Direct Numerical Control.Instead, Distributed Numerical Control is introduced.In such a system, a host computer communicates with many CNC machine tools via networks and download or upload programsWith Distributed Numerical Control systems, it is possible to monitor the activities in individual CNC machine tools on host computer. As a result, improved shop floor control is possible.
Conclusion
As I previously mentioned, CNC machines make our work easy. You can perform several tasks with the help of CNC like: mills, drills, boring machines, punch presses. You can use this machine in robotics, grinding, welding machinery, EDM, flame cutting, and inspecting equipment. As a mechanical engineer If you want your work to be easy. I would prefer you to use CNC and If you want to learn more about CNC .Abhyaz offers training on CNC which will help you in your job. Abhyaz offers a skill development program as well as an internship program where you can obtain more hands-on experience.
FAQs
Q1. What is the full form of DNC?
Ans. The full form of the DNC is “ Direct numerical control”.
Q2. What is G-code?
Ans. Sequence Number,used to identify each block within an NC program and provides a means by which NC command may be rapidly located. It is the program line number. It is good practice to increment each blog number by 5 to 10 to allow additional to be inserted if future changes are required.
Q3. What is the full form of G-code?
Ans. G-code stands for “Geometric Code”.
Q4. Does the Abhyaz platform provide training for digital manufacturing tools?
Ans. Yes, Abhyaz provides training as well as internships to obtain more
experience.To join as an intern visit www.abhyaz.com and you can apply there.
