Recent Advancements in CNC

In today’s world Technology is rapidly changing, to sustain in this race our institute provides the training on the CNC and VMC. These machines are more advanced and are best machines. This training is done in this best diploma college in pune region.


Let’s talk about the CNC. This concept of CNC is credited to John Person. He invent first NC control machine which is operated on the punched tape. First NC machine is manufactured in 1952 a three axis hydrotel milling machine. After that new class of machines called machining center that perform multiple machining operations was developed.

Based on the need for more complex and sophisticated aircraft parts, the Computer Numerical Control (CNC) concept was first introduced to advance the machineries in the aircraft industries shortly after World War II. The CNC process is used by the manufacturing sector to control a machine or a tool using a programmable computer. Today, CNC machining is widespread; it dominates the manufacturing sector, allowing for a considerable jump in productivity around the world. With the advancement of CNC technology, we have seen many advancements applied beyond the CNC industry, such as simplified programming language, improved engine communications, and customization. As CNC technology continues to evolve, we can say without a doubt that the most exciting progression of CNC is yet to come.

The Integration of the best of Two Worlds

Due to the nature of the concept, CNC programs used to be limited to only control the CNC machines that aid manufacturing processes throughout history. As time has passed, manufacturers have moved towards having a centralized system such as Enterprise Resources Planning software to manage resources and to track the productivity of machines. The next step that manufacturers are looking to embrace is to adopt an increasingly interconnected system that will streamline CNC machines with other machines and procedures. Commonly, CNC machines and manufacturing robots are closely paired in the manufacturing line due CNC’s strength in processing raw materials and robots’ capability in moving and packing produced goods. Thus, there are numerous attempts and collaborations between CNC developers, machine buildings, and robot manufacturers to create a simpler programming languages and better interaction between CNC machines and robots. For example, collaboration with CNC developers Siemens and robotic supplier KUKA has produced an interface that allows CNC operator to control both CNC machines and robots from a single control panel. With many more collaborations to come, it is exciting to see the progress that will elevate efficiency in utilizing the CNC.

Parts and Tools for All

Another notable advancement is the personalization of CNC Machining. Over the years, CNC 3D printers have made prominent progress, allowing individuals to tailor make any simple part like a square board to a complex tool such as a circuit board. This astonishing development is accompanied by a drastic cost decrease that enables the general population to acquire new technology or machines at low prices. Furthermore, as the technology advances, the size of a CNC 3D printer has also shrunk to the extent that it could now be placed inside a working space comfortably. With this technological breakthrough, individuals can now product customized tools with cost effectiveness at the comfort of their office or home; the progress in CNC 3D printing will forever alter industries around the world.


CNC is applied in various machineries

Milling

CNC Milling machine use computer control to cut the different materials. They are able to translate the various programs includes alphabets and numbers to move the spindle to various locations and depths. CNC milling performs many functions like face milling, end milling, tapping, drilling, slotting, blind hole drilling etc. Some CNC milling having 3 axes movement (X, Y and Z) and some have the one or more than one rotational axis which allows it for 3D printing

Lathes

CNC Lathes are cut the work piece when it is rotating. They are used to cut material at faster rate By using the indexable tools and drills. They can make apart at faster rates and with greater accuracy than conventional lathe. The lathe have same control specifications like CNC Milling but CNC lathe can operates in only two axes (X and Z),New models have more advancements for faster production and complicated profile


Non-conventional machining process

There are number of nonconventional machining process which are combines with the CNC to give more advancement in the manufacturing


CNC Plasma Machine

Plasma is used to cut materials like steel and other metals. In this machining plasma is formed by the heating the gas with the help of electric arc and melt the metal by high temp to perform machining. Now a days this process is combined and used with the CNC for the better accuracy. In many Fabrication plants uses this set up to cut the steel sheets at very faster rates.


CNC operated water jet cutters

In this the water jet matching is combined with the CNC to get the complicated parts with the better accuracy.Now a days some abrasive particles are added to the water jet to get the high material removal rate (MRR). This machining process is used to the high heat sensitive materials also used in the manufacturing machine parts aerospace machinery parts. CNC is applied to the many other non-conventional machining process like Electric Discharge Machining (EDM), Wire Cut Electric Discharge Machining (WEDM), LASER Beam Machining (LBM), Electron Beam Machining (EBM) and much more. There use is depends upon the material properties and product required.

CNC has revolutionized the manufacturing process worldwide, allowing for mass productions of goods and trades. We, at the Polytechnic pimpri chinchwad, believe that there are still many unknown and necessary CNC advancements that will once again change the way industries progress in the future. With unlimited possibilities, with the high and steady demand for CNC professionals, we believe that we are experiencing one of the best times for the CNC industry as a career.
