A jig is a tool used to guide and control the movement of a cutting tool, while a fixture is used to hold and position a workpiece during machining.

• Jigs are used to guide the cutting tool, while fixtures hold the workpiece.

• Jigs are used in drilling, reaming, and tapping operations, while fixtures are used in milling, grinding, and turning operations.

• Jigs are often custom-made for specific operations, while fixtures can be standardized and reused.

• Jigs are typically more comple...read more

The micrometre least count formula is the ratio of the pitch of the screw gauge to the number of divisions on the circular scale.

• The formula is LC = Pitch / Number of divisions on circular scale

• LC stands for least count

• Pitch is the distance moved by the spindle per revolution

• The number of divisions on the circular scale is the number of equally spaced divisions on the circular scale

• The formula is used to calculate the smallest measurement that can be made with a screw gauge

• Fo...read more

The second law of thermodynamics states that the total entropy of a closed system always increases over time.

• Entropy of a system tends to increase over time

• Heat cannot spontaneously flow from a colder location to a hotter location

• Efficiency of a heat engine is always less than 100%

• Entropy of the universe is always increasing

2D diagrams are flat while 3D diagrams have depth and volume.

• 2D diagrams are represented on a flat surface while 3D diagrams have depth and volume.

• 2D diagrams are used to represent objects or structures in a two-dimensional plane while 3D diagrams are used to represent objects or structures in a three-dimensional space.

• 2D diagrams are commonly used in engineering drawings, architectural plans, and circuit diagrams while 3D diagrams are used in computer graphics, video games, ...read more

Vernier caliper is a precision measuring tool used to measure length, diameter, depth, and thickness.

• Clean the measuring surfaces before use

• Close the jaws and check if the zero mark on the vernier scale aligns with the zero mark on the main scale

• Place the object to be measured between the jaws and tighten the lock screw

• Read the measurement from the main scale and the vernier scale

• Add the two readings to get the final measurement

• Use the depth gauge to measure the depth of hole...read more
