Control Systems

In the machinery sector, control systems are widely recognized as the most important software that determines the final result of the hardware performance. Both metal working and plastics and rubber injection and extrusion machines now would be installed with the control system rather than manually operation like before, and there are many famous control systems in the market that take the most percentages in the machinery market. In regard to the beginning of control, it is from analogy to digital. Before the invention of CNC system, there was the NC system, which was built in the era around 1940s and was designed based on the tools adjusted with motor units that is driven according to the punched tape, which is the servomechanism that serve as the early device that realizes the automation by the analogy rather than the digital measures. Later when computer was invented, digital system was invited into the field and thus the concept of computer based CNC system is realized.

For people working in the machinery sector, control systems are widely recognized as the most important software that determines the final result of the hardware performance. Both metal working and plastics and rubber injection and extrusion machines now would be installed with the control system rather than manually operation like before, and there are many famous control systems in the market that take the most percentages in the machinery market.

 

Beginning of control

Before the invention of CNC system, there was the NC system, which was built in the era around 1940s and was designed based on the tools adjusted with motor units that is driven according to the punched tape, which is the servomechanism that serve as the early device that realizes the automation by the analogy rather than the digital measures.

In the case of drilling

A CNC drilling machine is drilling machinery which is controlled by the computer numerical control system, a modern CNC drilling machine is one of the highly favored machine tool types for precision depth accomplishment that is designer for the hard material drilling tasks. Programmed CNC drilling is a profoundly studied and well evolved machine tool working model that can deal with multiple types of hole drilling and relevant boring tasks all at one drilling station due to its multitasking and convenient frame work design. For the development of this type of CNC drilling model, at the very first, numerical drilling machines were evolved from the design of conventional drilling machines at the midst of the 20th century, and after that digital technology of NC, which is the so called semi digital controlled drilling, a diversified version of drilling centers are widely applied in all kinds of industries for professional and precision usages, contributing a broad range of industrial achievements in the drilling tasks demanded by the customers.

 

In the case of turning

In regard to the turning mechanism controlling, a CNC lathe is also called a CNC turning machine, that is a machine tool that rotates a work piece on an axis (usually as the X axis) of rotation to perform various machining operations such as cutting, knurling, sanding, drilling, deformation, facing, and turning. Such machining procedures are conducted with tools that are applied to the work piece and to create an object with symmetry with the axis which is driven by the primary spindle. In this way, the clamping mechanism controlled by the CNC system is much more rigid and fixed due to the gravity effect compared to the horizontal methodology and manufacturers of vertical turning machines usually made their vertical turning machines into great manufacturing facilities for users in a variety of industrial sectors that pursue for high precision, such as automotive industry, aerospace sector, sport equipment application, and other fields with larger size work pieces processing.

 

In the case of milling

A CNC milling machine is the milling machine that is designed with the CNC feature, allowing the whole milling process to be done under the control of a computer numerical control (CNC) system. This type of machine is a highly developed machine tool that can deal with many kinds of mill tasks all at once. At first, CNC milling machine is developed from milling machines with enhanced repeatability, and since then, the development of this specific type of machine tools goes well in the industry, and after that, machine centers are widely applied in all kinds of industries, contributing a wide range of industrial efforts across fields and continents.

 

In the case of boring

A CNC boring machine is the machine tool with the machining process utilizes spinning tools to bore work piece materials by enlarging a hole that has already been drilled by means of a single-point cutting tool, such as in boring a gun barrel or an engine cylinder under the control of a computer numerical control (CNC) system. Today, this kind of machines is usually controlled by automatic programmed CNC system and the precision is controlled within a relatively small tolerance. The boring methods could be done on different directions that are based on the different tracks installed on the axes, which are installed on the moving tracks of the machine body. Many of the milling machines and machining centers are capable of boring operation for simple processing after the complicated milling mechanism. Furthermore, drilling machines are also designed with boring functionality now in order to keep up with the fast cycle time requirement.

 

CNC and automation

In the era of automatic manufacture, both automotive and 3C consumable electric sectors, manufacturers that need to proceed machining tasks in the 21st century tend to purchase machining centers for a wider application. Machine tools are the most fundamental capital goods for manufacturers and play the critical role that determines the final output of the end products, and the quality of the machine tool becomes the key point of the quality of the manufacturers’ final end products. The inventory of machine tools varies from time to time. Accordingly, now after the invention of the machining centers and the programmed controlling system (CNC, computer numerical control), the standards of machining become more and more rigid compared with the standards before.
