Q1. 01. Mechanical failures in Furnace 02. Metallurgical failures and their Remedy.
Mechanical and metallurgical failures in furnace and their remedies.
Mechanical failures can be caused by wear and tear, improper maintenance, or design flaws.
Metallurgical failures can be caused by improper heat treatment, contamination, or material defects.
Remedies for mechanical failures include regular maintenance, proper design, and replacement of worn parts.
Remedies for metallurgical failures include proper heat treatment, material testing, and quality control measures.
Q2. 03. How to decide cycle for NPD parts.
The cycle for NPD parts is decided based on material type, part geometry, required properties, and customer specifications.
Consider the material type and its heat treatment response
Analyze the part geometry and its heat treatment requirements
Determine the required properties such as hardness, toughness, and wear resistance
Take into account the customer specifications and any regulatory requirements
Perform trials and testing to optimize the cycle
Document the cycle and ensure r...read more
Q3. What is mechanical engineering?
Mechanical engineering is a branch of engineering that focuses on designing, analyzing, and manufacturing mechanical systems.
Involves designing and analyzing mechanical systems such as engines, machines, and tools
Includes studying materials, thermodynamics, fluid mechanics, and dynamics
Incorporates principles of physics and mathematics to solve engineering problems
Examples include designing car engines, HVAC systems, and manufacturing equipment
Q4. What machine knowledge you have
I have extensive knowledge in operating and maintaining various machines, including industrial equipment and computer systems.
Experience with troubleshooting and repairing mechanical equipment
Proficiency in programming and operating computer-controlled machinery
Familiarity with maintenance procedures for industrial machines
Knowledge of safety protocols for operating heavy machinery
Q5. how do we calcutate OEE?
OEE is calculated by multiplying Availability, Performance, and Quality.
Calculate Availability by dividing Operating Time by Planned Production Time.
Calculate Performance by dividing Actual Production by Maximum Possible Production.
Calculate Quality by dividing Good Parts Produced by Total Parts Produced.
Multiply Availability, Performance, and Quality to get Overall Equipment Effectiveness (OEE).
Q6. What is Gd&t and
Geometric Dimensioning and Tolerancing (GD&T) is a system for defining and communicating engineering tolerances.
GD&T is a symbolic language used on engineering drawings to specify the allowable variations in form, size, and orientation of features.
It uses symbols, such as squares, circles, and triangles, to define the tolerance zones for different features.
GD&T helps ensure that parts are manufactured to the correct dimensions and fit together properly in assemblies.
It is com...read more
Q7. Why is gear difine me
Gears are essential components in mechanical systems, providing torque and speed conversion.
Gears transmit power and motion between rotating shafts.
They can increase or decrease torque and speed depending on their size and arrangement.
Gears are used in a wide range of applications, from automobiles to industrial machinery.
Proper gear design and quality are critical for efficient and reliable operation.
Gear failure can result in costly downtime and safety hazards.
