What is non conventional machine?
The non-conventional machines employ the modern and latest technology in processing. In these machining methods, no direct contact between the machine tools and the workpiece. The tools used are infrared beam, laser beam, electric arc, plasma cutting, and electric beam.
What are the conventional machines used for machining of Mould parts?
In its conventional form, standard machining requires the manual use of lathes, milling machines and drill presses. With advanced technology, CNC machining has become the predominant means of creating more complex and accurate molds, while still using standard machining methods.
What is machining process and its types?
The three principal machining processes are classified as turning, drilling and milling. Other operations falling into miscellaneous categories include shaping, planing, boring, broaching and sawing. Drilling operations are done primarily in drill presses but sometimes on lathes or mills.
What is used for repetitive and commonly used machining operations?
Engine lathes are the most common type found in use by the general machinist or hobbyist. Turret lathes and special purpose lathes are more commonly used for applications that require repeated manufacturing of parts.
What is the need of non conventional machining?
The main reasons for choosing non-traditional machining processes are: To machine high steel alloys. To generate desired complex surfaces and. To achieve high accuracy and surface finish.
What is non traditional machining process?
A machining process is called non-traditional if its material removal mechanism is basically different than those in the traditional processes, i.e. a different form of energy (other than the excessive forces exercised by a tool, which is in physical contact with the work piece) is applied to remove the excess material …
What is conventional machine?
What is Conventional Machining? The conventional machining process uses a human operator to direct and control machining tools such as milling, boring, and drilling machines as well as lathes and other sharp cutting tools.
What is unconventional machining?
Definition Unconventional Machining Process is defined as a group of processes that remove excess (stock) material from work piece by various techniques involving Mechanical, Thermal, Electrical and chemical energy or combination of these energies but do not use a sharp cutting tools as it needs to be used for …
Which of the following is not the type of nontraditional machining?
Explanation: Electrochemical process, chemical machining and mechanical energy process are all the types of nontraditional machining. Apart from these, photochemical, chemical milling, ultrasonic machining, laser beam machining etc.
What is the meaning of non-conventional?
Definition of nonconventional : not conventional : not conforming to convention, custom, tradition, or usual practice : unconventional nonconventional teaching methods nonconventional energy sources Ten years ago, the alternative press was hard to find but easy to define.
What is the meaning of non conventional machining?
Non-traditional machining, also known as “non-conventional machining” or “modern machining method”, generally refers to the machining method of removing or adding materials with energy of electricity, heat energy, light energy, electrochemical energy, chemical energy, sound energy and special mechanical energy, so as to realize materials being
What is the traditional machining method?
The traditional machining method is to use mechanical energy and cutting force to remove excess metal so that the part has a certain geometric shape, size and surface roughness. It requires tool material to be harder than workpiece material.
Is conventional machining an additive or subtractive manufacturing method?
With the recent proliferation of additive manufacturing technologies, conventional machining has been retronymously classified, in thought and language, as a subtractive manufacturing method. In narrow contexts, additive and subtractive methods may compete with each other.
What are the advantages of unconventional machining?
The unconventional machining it uses some form of energy for metal removal there is no direct contact between the tool and workpiece. his process is also uneconomical, time-consuming and sometimes impossible to machine complex shapes. It has a high degree of accuracy. It provides a great surface finish. The complex shapes can be easily machined.
