Manufacturing Process Flashcards
This is done by placing a piece of metal, usually in the form of
sheet, plate, strip, or rod, between two blades of knives
Shearing
Process of moving hard metal saw blade with teeth along its edge
across a metal to be cut
Sawing
manually- operated saw used for cutting metals by pushing and pulling the blade on the metal being cut
Hand hacksaw
is simply an improvement of hand hack saw. It is an extremely economical and efficient way of cutting bigger sizes of
metal bars
Power hacksaw
uses an endless blade that moves past the piece being cut in only one direction.
Band saw
One of the fastest method of cutting bars or steel plates having a thickness of 1/16 to 6 inches
Flame cutting
Uses electricity and compressor to carryout cutting of metals,
especially stainless steel, at a faster rate compared with other
cutting tools and equipment.
Plasma cutter
process of cutting or squaring of the end of a piece of work.
Facing
done with a combination of drill and countersink
Center drilling
the work is first placed on the centers, and the cutting tool is set for cutting
Straight turning
commonly performed with a drill press or by a lathe. In here, the work piece is held in a lathe chuck while the drill, reamer, countersink, or counter boring
tool is held in the tailstock
Drilling Reaming and Counter Boring
cutting and enlarging of a round hole to make a more
exact size and accurate with its axis
Boring
process of making threads on screw either righthand, left-hand, external, or internal threads
Threading
It is the common method of joining metal sheets, especially
non-ferrous metals
Soldering
The joining technique of metal using oxyacetylene welding
equipment by melting a non-ferrous filler rod at a
temperature above 427°C but below the melting point of
metal being joined
Brazing
The common gas welding process using oxygen and acetylene gases in providing heat to melt and join metal by means of fusion
Oxyacetylene Welding
special valve that properly mixes the oxygen and the acetylene gases
Regulator
carries the gases from the cylinder to torch. Red hose is used for acetylene gas; while, green hose is for oxygen gas.
Hose
The process of welding metal by passing high current into a flux-coated welding rod. The flux serves as shield to prevent oxidation to produce stronger weld
Arc welding
It uses the heat generated by electric current passing through a small area of the metal being joined. The pressure forces heat the area together until they have fused
Resistance welding
the common form of resistance welding
Spot welding
uses continuous roll-fed
welding rod
Metal inert gas (MIG) Welding
is widely used for welding aluminum, stainless steel and other non-ferrous metals
Tungsten inert gas (TIG) Welding
The manufacturer fabricates the machine by piece, only one at a time. Usually one to two persons are commissioned to do the entire work to produce the machine. The machine basically is directly contracted from individual farmer or user
By piece
The manufacturer fabricates the machine in several number of pieces as per contract with the dealer
By batch
The manufacturer produces the machine beyond the number of pieces produced in the batch system. Even without direct order or purchase from the customer or dealer, the manufacturer still produces the machine for possible unseen market
Mass production
small manufacturing enterprises that are usually capable of manufacturing agricultural machines by piece only. They are usually backyard fabrication in operation and basically use common fabrication equipment such as hand saw, welding machines, and some power drill and sanders
Small manufacturer
capable to operate and produce
agricultural machines by batch and do mass production of small
machines, if ever needed. They have more equipment and
facilities to do manufacturing than small manufacturers do. Special process needed in the manufacture of a certain machine is done by subcontracting to other machine shops
Medium-size manufacturer
capable of mass producing
agricultural machines because they have almost complete line of equipment needed in manufacturing. Small and medium manufacturers sometimes request subcontracting job fromo
large-size manufacturers
Large-size manufacturer
are those producing one or several types of farm machinery and usually do not sell other items from other manufacturers
Manufacturers
manufacture their own line of item but also sell either consigned items or several brands of
single-cylinder engines, pumps, pump set, and other types of
farm machinery.
Manufacturer-dealer
carry several items and brands from various sources and are not usually engaged in manufacturing and fabrication.
