Q1. What is VMC machin and axis
Ans. 
VMC stands for Vertical Machining Center. It is a type of CNC machine that operates on three or more axes.
• VMC machines are used for precision cutting, drilling, and milling of metal and other materials.

• They have a vertical spindle that moves up and down, and a table that moves in the X, Y, and Z axes.

• The number of axes can vary depending on the machine, with some having up to five axes.

• Examples of VMC machines include ...read more

Q1. What do you meant by basic size?
Ans. 
Basic size refers to the theoretical size of a part before any tolerance is applied.
• Basic size is the starting point for applying tolerances in manufacturing.

• It is the size that the part must be in order to function properly.

• For example, if a hole is specified to have a basic size of 10mm, it means that the hole must be exactly 10mm in diameter for the part to work correctly.

Q2. What is nominal size?
Ans. 
Nominal size refers to the size of a part or component as designated by its name or label.
• Nominal size is the size of a part as indicated by its name, but may not be the exact physical dimensions.

• It is commonly used in manufacturing to simplify communication and standardize sizes.

• For example, a 2x4 piece of lumber actually measures 1.5 inches by 3.5 inches.

Q1. What is limits?
Ans. 
Limits refer to the maximum or minimum values that a machine or process can handle.
• Limits are set to ensure the machine operates within safe parameters.

• Exceeding limits can result in damage to the machine or product.

• Examples include temperature limits, speed limits, and weight limits.

Q1. What is mean by torque
Ans. 
Torque is a measure of the twisting force applied to an object.
• Torque is the product of force and the distance from the axis of rotation.

• It is a vector quantity, meaning it has both magnitude and direction.

• Torque is commonly used in mechanical systems to measure rotational force.

• For example, when tightening a bolt with a wrench, the torque applied determines how tight the bolt becomes.

• Torque is measured in units of for...read more

Q2. What is mean by stress.and strain
Ans. 
Stress is the force applied to a material, while strain is the resulting deformation or change in shape.
• Stress is the external force or load applied to a material.

• Strain is the measure of deformation or change in shape that occurs in response to stress.

• Stress and strain are related through the material's elastic properties.

• Stress is typically measured in units of force per unit area (such as pounds per square inch or p...read more

Q3. What is mean by youngs modulus ?
Ans. 
Young's modulus is a measure of the stiffness of a material.
• Young's modulus is the ratio of stress to strain in a material under tension or compression.

• It is a measure of how much a material will stretch or compress under a given amount of force.

• Materials with a high Young's modulus are stiffer and less elastic than those with a low Young's modulus.

• For example, steel has a high Young's modulus, while rubber has a low Y
