This aims to practice metalworking for a student who supposes to learn in metal works. Learn the basic metalworking tools and equipment wherein it easy for them to participate in their school activities that related to metal works.
1. I. Introduction
The aims of this activity plan are to highlight most of the wide variety of tools and equipment
used in metal shops. The plan includes a lesson/demonstration with a PowerPoint presentation
or in actual with the use of props in all of the tools, and the student will complete tool and
machine identification activities. The focus of the activity is broad, and it will be applicable in
the majority of school sites.
II. Objectives
The student will be able to:
To Identify the tools and equipment in their own school metal shop
To Explain the function and useful of the tools and equipment
To Discuss safety implications of each tool and equipment’s
To Identify one or more operation that is possible with each equipment and tools
To Recognize that tools and equipment’s should always be used only for their intended
purpose
A. What is Metal Working?
Metalworking is the process of working with metals to create individual parts, assemblies, or
large-scale structures. The term covers a wide range of work from large ships and bridges to
precise engine parts and delicate jewelry. It therefore includes a correspondingly wide range of
skills, processes, and tools.
Metalworking is a science, art, hobby, industry and trade. Its historical roots span cultures,
civilizations, and millennia. Metalworking has evolved from the discovery
of smelting various ores, producing malleable and ductile metal useful tools and adornments.
Modern metalworking processes, though diverse and specialized, can be categorized as
forming, cutting, or joining processes.
B. Basic Metal Working tooland Equipmets
Metals are so useful that we need to know more about them and the tools that are used to
shape, cut, form, and finish them. The following are the basic tools and equipment used in
doing metalworks:
1. Straightedge. A steel rule used to test the flatness of a workpiece.
2. Outside caliper. This is used to measure the outside dimensions of either a flat or round
stock.
3. Inside caliper. This is used to measure the diameter of holes or widths of keyways and slots.
2. 4. Hermaphrodite caliper. This consists of two legs, one is like that of a divider and the other
one is like the leg of an inside caliper.
5. Try-square. This consists of a thick beam sometimes called the stock and a thin blade set at
90° angle.
6. Divider. This is similar in construction to calipers except that the legs are straight and
terminates in sharp points.
7. Tape rule. This comes in different lengths but commonly in two metre lengths. They are
useful in measuring large dimensions such as lengths of metal bars and width of iron sheets.
8. Vernier caliper. This is a device which measures dimensions more accurately than most
other measuring tools and is commonly used in machine shop work.
9. Micrometer. This is used to measure very small dimensions.
10. Layout table. This is actually made of granite or cast iron. For very simple layout work,
any plain surface such as an ordinary table top will do.
11. Scribers. These are generally used with a straight edge rule to draw straight lines.
12. Center punch. It is used to mark the location of the centers of holes. The wider the angle of
indentation permits a drill bit to start holes accurately.
13. Bench vise. This is the most commonly used tool in benchwork to securel hold small work
for sawing, chipping, drilling, reaming, polishing, and tapping operations. Vises are made of
heavy cast iron or cast steel.
14. Hammer. The most commonly used in benchwork are the ballpen, straight peen, and
crosspeen hammers.
15. Screwdriver. Instruments designed to drive in and take out screws.
16. Wrench. are made in various shapes and sizes and are used for gripping, fastening,
turning, tightening and loosening things like pipes, pipe fittings, nuts and bolts.
17. Pliers. used for gripping something round like a pipe or rod, some are used for twisting
wires, and others are designed to be used for a combination of tasks including cutting wire.
18. Hacksaw. This is used in cutting metals and other materials like fiber and plastics. It is
composed of a handle, a frame, and a blade.
19. Chisel. Is the simplest form of cutting tool. It is made of heat-treated steel with the cutting
edge shaped differently for various chipping requirements.
3. 20. Snips. Are tools necessary in the metalworks shop especially when working with metal
sheets that are very thin (1/16 of an inch thick). The snips are generally called tinner snips as
these are the main tools of a tinsmith.
21. Hand drills. Are tools used for drilling small holes through metals, wood, or plastic. It
consists of a shank which is attached to a toothed wheel with a handle. The toothed wheel or
gear turns another toothed wheel and carries the shaft which holds the chuck and the drill bit.
22. Twist drill. This is a cutting tool consisting of a steel rod with two flutes running around its
body, the point of which is ground so that cutting edges are formed. Twist drills are
manufactured from forged steel. They are made with neither a straight or tapered shanks.
Small twist drills are generally straight while the bigger ones tapered.
C. SafetyPracticesinMetalworks
No metal shopwork activity is worth pursuing if it cannot be done safely. Filipinos in general
take safety for granted. This may be due partly to the fact that schools lack the safety resources
of a basic shop. Protective devices are generally left out in requisitions for shop tools and
materials. Despite these, safety should be dutifully practiced in the shop. Remember that the
right way is the safe way.
The following are important points to remember when engaged in shopwork:
1. The shop is a place of work, so do not engage in horseplay.
2. Never use a machine you are not familiar with or you do not know how to operate. Always
ask the teacher’s permission before operating a machine so you can be guided accordingly.
3. Keep hand tools such as files, screwdrivers, and scribers on the table and in the tool
cabinet when not in use, never in your pockets. They may hurt you or others.
4. Use only tools that are in good condition. Files or hammers with cracked handles are
dangerous to use. Mushroom heads of cold chisels should be ground regularly to prevent
accidents.
5. Keep your hands dry before touching any power tool. Make sure you are not standing on a
wet spot.
6. Keep your hair short or cover it with a cap when working.
7. Never wear long sleeves when working with machines . Remove wristwatches, bracelets,
rings, and neklaces before working with machines.
8. Protect your eyes from flying chips and metal abrasives by wearing goggles and eye shields
when grinding, buffing, chipping, and pouring hot metal.
9. Report accidents to the teacher no matter how minor. If a wound is inflicted, this should be
treated at once.
10. Keep tools in good working condition.
11. Keep the work area clean and orderly. Remove things and materials which can hamper your
current work.
12. Keep flammable materials such s paint, gasoline, and thinner in a cool, dry place away from
the work area.
4. 13. Clean oil spills on the floor immediately.
14. Tools and materials (especially cylinders) dropped on the floor can cause accidents. Pick
them up immediately and store them in proper places.
