- 17. Basic woodworking tools and equipment: Functions and Maintenance
- 18. A tool is a device that can be used to produce an item or accomplish a task, but that is not consumed in the process A. Hand tools are tools manipulated by hands without using electrical energy such as: puller, hacksaw, pull-push rule, pliers, hammer, and others.
- 19. C. Pneumatic tools are tools or instruments activated by air pressure. Pneumatic tools are designed around basic devices: the air cylinder, the vane motor, and the sprayer B. Machine/Power tools are tools manipulated by our hands and with the use of electrical energy such as: electric drill, grinding wheels, vacuum cleaner and others.
- 20. A. Hand tools Screwdrivers: are used to drive or turn screws. The common type has a single flat blade for driving with slotted heads. The other type has the cross slotted head
- 21. Hammers: are mostly used tools in the shop. They should be gripped at the end of the handle.: Pliers: are specified types of adjustable wrenches. The two legs move on a pivot so that items of various sizes can be gripped.
- 22. Wrenches: are used to turn screws, nuts and bolts with hexagonal heads. - Hexagonal|| means six- sided. A variety of wrenches are used in the shop.
- 23. B. Machine/Power Tools 1. Electric drill has an electric motor that drives a chuck. The chuck has jaws that can be opened and then closed to grip a drill kit
- 24. 2. Grinding tool can be either bench-mounted or installed on a pedestal. They may either have a wheel, view wheel, or two grinding wheels.
- 25. 3. Vacuum cleaner is used for cleaning the floor and car interiors after service
- 26. C. Pneumatic tools 1. Pneumatic Torque Wrench. This wrench uses compressed air to quickly and powerfully turn nuts, bolts, and other objects
- 27. 2. Air chisel uses reciprocating motion to drive a cutting hammering tool. An air hammer drives a chisel to cut off a nut that has frozen to a stud. It can be used with a variety of tools-cutters and punches to do many jobs.
- 28. 3. Air drill is lighter than a comparable electric drill. Repeatedly stalling or overloading does not damage or overheat the air drill
- 29. Basic Maintenance of Electrical Tools and Equipment 1. Clean out the Dust. To make sure that your electric tools are ready to go when you are, keep them clean and free of dust. 2. Check the Cords. Look for tear/cut insulator on the power cords on your electric tools. This will ensure that your electric tool can get the power that it needs to function without an accident
- 30. 3. Use the right tool correctly. Use tools correctly and for their intended purposes. Follow the safety directions and operating procedures recommended by the manufacturer. When working on a circuit, use approved tools with insulated hand. 4. Protect your Tools. Keep tools and cords away from heat, oil, and sharp objects. These hazards can damage insulation. If a tool or cord heats up, stop using it. Report the condition to a supervisor or instructor immediately
- 43. Sawing Sawing is one of the most common forms of wood manufacturing. It involves cutting the wood into various shapes and sizes. Sawing can be done by hand, but most often it is done with a sawmill. Sawmills can use a variety of saw blades, including circular saws, bandsaws, and chainsaws, to create custom shapes and sizes for the desired product.
- 44. Planning The purpose of planning is to make the wood smooth and even. This is done by running the wood through a planer, which removes small amounts of wood at a time. Planers can come in different sizes and shapes, depending on the type of product being made.
- 45. Drilling Drilling is a process where holes are made in the wood. This is usually done with a drill press but can also be done with hand tools. The types of drills used will depend on the type of product being made and the size of the holes needed.
- 46. Shaping Shaping is the process of forming the wood into the desired shape. This can be done with a variety of tools, such as routers, chisels, and hand planes. The type of tool and the type of wood will determine the type of shape that can be achieved.
- 47. Sanding Sanding is the process of removing material from the wood by using abrasive materials. This is usually done with sandpaper but can also be done with power tools. Sanding is done to make the wood smooth and can also be used to remove imperfections or stains.
- 48. Finishing Finishing is the process of applying a protective coating or sealant to the wood. This can be done with varnish, stain, lacquer, oil, or wax. Finishing can be done with a brush, a spray gun, or a power buffer.
