Most CNC machines have 3 or 5 axes, but some advanced machines can have up to 9 axes.
Most common CNC machines have 3 axes: X, Y, and Z.
Some CNC machines have 5 axes: X, Y, Z, A, and B.
Advanced CNC machines can have up to 9 axes, including rotational axes for more complex operations.
The number of axes in a CNC machine determines the complexity of the operations it can perform.
G and M codes are programming languages used in CNC machines to control various functions and operations.
G codes are used to control the movement and positioning of the tool or workpiece on a CNC machine.
M codes are used to activate or deactivate specific machine functions like coolant flow or spindle rotation.
Example: G01 is a code for linear interpolation, while M03 is a code for spindle start in a CNC program.
First angle projection is commonly used in Europe and Asia, while third angle projection is commonly used in North America.
First angle projection places the object in the first quadrant, with the plane of projection between the observer and the object.
Third angle projection places the object in the third quadrant, with the plane of projection behind the object and the observer.
In first angle projection, the top view is...
2 stroke engine completes the power cycle in 2 strokes of the piston, while 4 stroke engine completes it in 4 strokes.
2 stroke engine has intake, compression, power, and exhaust in 2 strokes
4 stroke engine has intake, compression, power, and exhaust in 4 strokes
2 stroke engines are simpler and lighter but less fuel efficient
Examples of 2 stroke engines: chainsaws, mopeds, dirt bikes
Examples of 4 stroke engines: cars, m
The least count of a digital vernier caliper is the smallest measurement that can be read on the scale.
The least count of a digital vernier caliper is typically 0.01 mm or 0.0005 inches.
It is determined by the number of divisions on the main scale and the number of divisions on the vernier scale.
For example, if the main scale has 10 divisions and the vernier scale has 9 divisions, the least count would be 0.1 mm / 10 =

Die casting and machining defects are common in manufacturing processes.
Die casting defects include porosity, shrinkage, cold shuts, and flash.
Machining defects include burrs, chatter marks, and tool marks.
Die casting defects can be caused by improper temperature, pressure, or metal flow.
Machining defects can be caused by dull tools, improper speeds and feeds, or poor fixturing.
Defects can lead to part failure, reduced
Filling and high speed ratio formula is used to calculate the filling time of a container with a specific volume of liquid at a given flow rate.
Filling and high speed ratio formula is V/Q
V is the volume of the container and Q is the flow rate of the liquid
The formula is used to determine the time it takes to fill a container with a specific volume of liquid at a given flow rate
The higher the flow rate, the faster the c

Micrometre is a precision measuring instrument used to measure small distances accurately.
Micrometre consists of a stationary anvil and a movable spindle.
The object to be measured is placed between the anvil and spindle, and the spindle is turned to make contact with the object.
The measurement is read from the scale on the sleeve and thimble of the micrometre.
Micrometres are commonly used in engineering and manufacturi...
Degree of freedom refers to the number of independent variables or parameters that can vary in a system.
Degree of freedom is the number of variables that can be changed independently without affecting the overall system.
In mechanics, a rigid body in a plane has 3 degrees of freedom - two translations and one rotation.
In thermodynamics, a simple compressible substance has 2 degrees of freedom - temperature and pressure.

Forging and rolling are two common metalworking processes used to shape metal into desired forms.
Forging involves shaping metal by applying compressive forces, typically using a hammer or press.
Types of forging include open-die forging, closed-die forging, and impression-die forging.
Rolling involves passing metal between rollers to reduce thickness or change shape.
Types of rolling include hot rolling, cold rolling, and
