Vizag Steel Interview Questions and Answers

Q1. What is the chip relieving angle
Ans. 
The chip relieving angle is the angle between the cutting edge of a tool and the surface of the workpiece.
• The chip relieving angle is important in machining operations as it affects the chip formation and evacuation.

• A larger chip relieving angle allows for better chip flow and reduces the chances of chip clogging or built-up edge.

• Different materials and cutting conditions may require different chip relieving angles for...read more

Q2. What is the pitch of the thread
Ans. 
The pitch of a thread refers to the distance between adjacent threads on a screw or bolt.
• Pitch is typically measured in millimeters or inches.

• It determines the tightness or looseness of the fit between the screw and the threaded hole.

• A finer pitch means more threads per unit length, resulting in a tighter fit.

• A coarser pitch means fewer threads per unit length, resulting in a looser fit.

• For example, a screw with a pitc...read more

Q3. What is the lip angle on drill bit
Ans. 
The lip angle on a drill bit refers to the angle formed between the cutting edge of the drill bit and the surface of the material being drilled.
• The lip angle affects the cutting action and chip formation during drilling.

• A smaller lip angle provides a more aggressive cutting action, but may cause the drill bit to wander or chatter.

• A larger lip angle provides a more controlled cutting action, but may generate more heat.

• C...read more

Q4. How do calculate pitch circle dia. in spur gear
Ans. 
Pitch circle diameter in spur gear is calculated using the formula: PCD = (Number of teeth / Diametral pitch)
• The pitch circle diameter (PCD) is the diameter of the imaginary circle that passes through the center of the gear teeth.

• To calculate the PCD, you need to know the number of teeth on the gear and the diametral pitch.

• The formula to calculate PCD is PCD = (Number of teeth / Diametral pitch).

• For example, if a gear ...read more

Q5. What is the formula for Feed calculation
Ans. 
The formula for feed calculation in mechanical engineering is Feed = (Number of teeth on the cutter x RPM x Chip load)
• Feed is a crucial parameter in machining operations

• It determines the rate at which the cutting tool advances into the workpiece

• The formula for feed calculation involves the number of teeth on the cutter, RPM (revolutions per minute), and chip load

• Chip load refers to the thickness of the material removed...read more

Q6. Why forged steel is used for machine parts
Ans. 
Forged steel is used for machine parts due to its superior strength, durability, and resistance to wear and tear.
• Forged steel has a higher tensile strength compared to other materials, making it ideal for heavy-duty machine parts.

• It has excellent toughness and impact resistance, ensuring the parts can withstand high loads and vibrations.

• Forged steel is highly resistant to wear and tear, reducing the need for frequent r...read more

Q7. What was the distortion during welding
Ans. 
Distortion during welding refers to the changes in shape or dimensions of the welded material caused by the heat and cooling processes.
• Distortion occurs due to the expansion and contraction of the material during welding.

• It can result in changes in the straightness, flatness, or angularity of the welded components.

• Distortion can be minimized by using proper welding techniques, such as preheating, controlling heat input...read more

Q8. What was the remidy to avoid dostortion
Ans. 
To avoid distortion, proper design, material selection, and manufacturing processes should be followed.
• Use appropriate design techniques to minimize stress concentrations.

• Select materials with suitable mechanical properties to withstand applied loads.

• Ensure proper heat treatment and surface finishing to reduce residual stresses.

• Implement accurate manufacturing processes to maintain dimensional stability.

• Perform regular...read more

Q9. What measure u adopt while doing gas cutting of steel to avoid distortion.
Ans. 
To avoid distortion while gas cutting steel, measures like preheating, using proper cutting speed, and cooling are adopted.
• Preheating the steel before cutting to reduce thermal shock

• Using proper cutting speed to prevent excessive heat buildup

• Cooling the steel after cutting to prevent warping

• Using a jig or fixture to hold the steel in place during cutting

• Using a smaller cutting torch tip to reduce heat input

• Using a back...read more

Q10. Distortion took place on longer products, to avoid this do stich cutting instead of doing continuos gas cutting. After cooling/ normal temp. then remove/cut the stiches. Sothat it won't b distorted.
Ans. 
Stitch cutting can be used to prevent distortion on longer products by cutting them into smaller sections and then removing the stitches after cooling.
• Distortion can occur on longer products during gas cutting.

• Stitch cutting involves cutting the product into smaller sections using stitches.

• After cooling or reaching normal temperature, the stitches are removed.

• This method helps to prevent distortion on the product.

• Examp...read more
