What is G-code and M code?

G codes are geometric codes, while M codes are related to the machine functions. G-code is for product design while M-code is related to stop/start machines. G-code activates the Numerical Control(NC) machine while the M-code activates the PLC of the machine.

What is used in non traditional machining?

Non-traditional machining has the following characteristics: The hardness of tool materials can be significantly lower than that of workpiece materials; The material can be processed directly using energy such as electric energy, electrochemical energy, sound energy or light energy.

Which one is non traditional machining process?

Casting, forming, powder metallurgy are such processes to name a few. … Similarly, Abrasive Jet Machining (AJM), Ultrasonic Machining (USM), Water Jet and Abrasive Water Jet Machining (WJM and AWJM), Electro- discharge Machining (EDM) are some of the Non Traditional Machining (NTM) Processes.

Why nuclear energy is non-conventional?

Although nuclear energy is considered clean energy its inclusion in the renewable energy list is a subject of major debate. … The five renewable sources used most often are biomass, wind, solar, hydro and geothermal. Nuclear energy on the other hand is a result of heat generated through the fission process of atoms.

Why CNC machines are used?

One reason for using CNC machining for production is efficiency. Since computers are used to control machines, it means that all major operations of production can be automated to increase speed and quality of manufacturing. … By using CNC machines, identical parts can made with the highest accuracy levels.

What are the advantages of using CNC machines?

What is difference between conventional and nonconventional sources of energy?

The conventional sources of energy are non renewable by any natural process. Non-conventional energy resources are renewable. These resources are available in a limited quantity. Non-conventional energy sources are eco-friendly in nature.

What are the types of CNC machines?

According to the functions or types of machined parts, CNC machines can be classified into five types: CNC milling machines, CNC lathes, CNC drilling machines, CNC plasma cutters, and CNC grinders.

What are the advantages and disadvantages of conventional energy sources?

Conventional energy sources are also known as a non-renewable energy source and have the following advantages:The efficiency of the energy source is high.This energy source is a well-known source.The production expenses are low.

What is the most common CNC machine?

CNC Milling Machine One of the most common types of CNC machines, a CNC mill utilizes computer controls to cut various materials. Mills can translate specific programs of numbers and letters in order to move the spindle in various ways.

What do you mean by non conventional machining process?

An unconventional machining process (or non-traditional machining process) is a special type of machining process in which there is no direct contact between the tool and the workpiece. In unconventional machining, a form of energy is used to remove unwanted material from a given workpiece.

What are the examples of non-conventional sources of energy?

Nonconventional energy sources (also called alternative energy sources) are any sources or substances that can be used to produce fuels, other than conventional fuels. These are sources that are continuously replenished by natural processes, including biomass, hydropower, nuclear power, solar energy, and tidal energy.
