Mechanical Process Interview Question & Answer-2019
The mechanical processing workshop is equipped for all
necessary machining operations such as milling, turning, drilling, sawing
and honing for the production of components according to the customer’s specific
requirements.
This video shows
common mechanical process interview question 2019 which is helps for engineer.
Question Number: 1 what is boring, drilling, milling, drawing
& grinding process?
Answer:
BORING – Opening out or increasing the diameter of an
existing drilled or cored hole by means of a boring tool.
DRILLING – Power or hand operated method for the production
of holes in metal or other solid materials with a drill.
GRINDING – Finishing operation designed to give to parts
already machined the necessary precision of form and accuracy of dimensions by
the removal of excess material due to the cutting action of grains of abrasive
in a wheel or disc.
DRAWING – Process, in press work, which involves reducing
the diameter or cross-sectional dimensions of a cup, shell, tube, bar or wire.
MILLING – Operation in which a work piece is given a
specific shape or form by means of a rotating cutter having many cutting teeth.
Question
Number: 2 what is difference between brazing, soldering and welding process?
Answer:
BRAZING –
Joining two pieces of metal without melting either one by using a brazing alloy
(copper zinc alloy i.e., brass) that melts at a lower temperature than the
materials being joined.
SOLDERING –
Operation of joining two or more parts together by molten metal.
WELDING –
Joining of metals by the application of heat, without the use of solder or any
other metal or alloy having a lower melting point than the metals being joined.
