Production Engineering Interview Questions and Answers
Question - 11 : - What Is Difference Between Lean Manufacturing And Jit (just In Time)?
Answer - 11 : -
Lean Manufacturing: It takes the concept of JIT and re-examines it from the customer point of view. Anything that is produced should add something of valuable to the customer’s requirement. For example, if you are making stereo system for a luxury car, you will think from the customer point of view like sound quality, durability, space occupancy, loud or medium sound, etc.
JIT (Just-in-Time): This methodology is designed to ensure that a product or part would arrive just in time to be used. This technique saves the cost behind the unused inventory, and eliminating the need of piling up inventory.
Question - 12 : - What Is The Least-count Of Vernier Caliper & Micrometer?
Answer - 12 : -
A) Vernier Caliper Least Count
LC = ( Value of 1 Main Scale Division ) / ( Total number of vernier scale divisions )
LC = 0.1 mm = ( 1 mm / 10 divisions )
LC of Vernier Caliper = 0.1 mm
B) Micrometer are also called Screw Gauge.
Least count of Micrometer
Least count of Micrometer
Least Count of Micrometer= 0.01 mm
Question - 13 : - What Is Qms?
Answer - 13 : -
QMS stands for Quality Management System; it documents all necessary information about company’s design and operational controls, including issue reporting, monitoring, continuous improvement and training, to make sure that company delivers continuous product.
Question - 14 : - What Is Batch Production?
Answer - 14 : -
Batch production is a manufacturing technique, where components or goods are produced in groups and not in a continuous stream. This methodology is mainly used when similar items are produced together.
Question - 15 : - What Is The Challenge In Manufacturing Products?
Answer - 15 : -
Main challenge in manufacturing is to develop better production processes, ensure the right material and component supplies at the least cost, decrease production time, eliminate wastage and maintain quality in the final product.
Question - 16 : - What Is Gmp?
Answer - 16 : -
GMP is a good manufacturing practice and is recognized worldwide for the control and management of manufacturing and quality control testing of foods, medical devices and pharmaceutical products.
Question - 17 : - What Are The Software’s Which Can Be Useful In Manufacturing Unit?
Answer - 17 : -
In manufacturing unit, software that can be useful are Manufacturing ERP and Material Management. Some of the companies that provide the manufacturing software solution are SAP, Oracle ERP system, etc.
Question - 18 : - What Is Product Report?
Answer - 18 : -
A product report is a general term used to represent design, manufacturing, quality, sales and repair information about a product.
Question - 19 : - Explain How Can You Calculate Manufacturing Work In Progress?
Answer - 19 : -
Manufacturing work in progress is when manufacturing firm transforms material into the work in process which includes raw material, labour and factory overhead. You can calculate all the below factors to know the costing for the manufacturing work in progress.
- Labour costs
- Raw material inventory costs
- Production cost
- Cost of ending work in process for the accounting period.
Question - 20 : - List Out The Factors That Can Affect The Manufacturing Process?
Answer - 20 : -
The factors affect the manufacturing process are:
Supplies: A well-managed supply and inventory is very crucial in order to run manufacturing process smoothly. The manufacturers must brace themselves up and ready to overcome any unexpected delays in supplies due to weather or transportation hindrance.
Equipment: Equipment’s are the central unit for any manufacturing plant; regular maintenance are utmost necessary to avoid a breakdown in the middle of production. Identify the means of improving the efficiency of every part of the equipment.
Factory Overhead: Without power supply, manufacturing is not possible. Always keep plan B ready in case of temporary power cut down.
Special Parts: Replacing any special spare parts with different specification may slow down your production, so before ordering any special spare parts ensure it fits your demand especially if it is imported from long distance.
Work Force: Human resource is equally important and plays a major role in manufacturing unit.
