All the modern are completely electronic while more industrial activities such as ultrasonic , hole-punching, and laser cutting, etc. have been included in the system. The early used in the 1940s make use of analog control method for its operations, leading to high rate of material wastage, non-uniformity of parts, and other defects.
There are many types of currently available for industrial applications. However, few of them have been highlighted here based on their popularity and dominance in the field.
Here are major types of modern :
These are machines used in milling operations of metals and other solid materials in the industry. They are capable of running on programs comprised of the number and letter-based prompts which guide pieces across various distances. The employed for mill could be based on either G-code or some unique language developed by a manufacturing team. They consist of a 3-axis system which are X, Y, and Z while some new ones may have more than just the 3-axis system.
With CNC technology, can cut pieces in a circular direction with indexable tools. The cuts employed in this way may be carried out with precision and high velocity. The can be used to produce complex that wouldn’t be possible on manual operations. The same control functions that for may for CNC , such reveals the similarities of the two . The can be directed by G-code or unique proprietary code. Most of the consist of two axes -X and Z.
ELECTRIC DISCHARGE MACHINES (EDM)
They are referred to as die sinking and spark machining. It is a process that molds workpieces into particular shapes with electrical sparks. With the , current discharges occur between two electrodes, and this removes sections of a given workpiece. When the between the electrodes becomes smaller, the electric field becomes more intense and thus stronger than the dielectric. This makes it possible for a current to between the two electrodes. Consequently, portions of a workpiece are removed by each electrode.
The subtypes of EDM include:
EDM, whereby spark erosion is used to portions from an electronically conductive material.
Sinker EDM, where an electrode and workpiece are soaked in dielectric fluid for the purpose of piece formation.
In a process known as flushing, debris from each finished workpiece is carried away by a liquid dielectric which appears once the current between the two electrodes has stopped and is meant to eliminate any further charges.
In this , a material is cut with a plasma torch. It is a process that is foremost applied to metal materials but can also be employed on other surfaces. In the process, plasma is generated through a combination of compressed air and electrical arcs in order to produce the speed and heat necessary to cut metal.
Water are tools that cut hard materials like granite and metal with high-pressure applications of water. In some cases, the water is mixed with sand or other strong substance. It is a process used often for the shaping of industrial .
For materials that could not bear the heat-intensive processes of the , water are employed as a cooler alternative. With that application, it has gained relevant in a wide range of sectors such as the aerospace and mining . It is the most suitable for the carving and cutting of hard materials with high thermal conductivity.
Besides the above-explained , others which are not popular in industrial applications are:
- Foam cutters
