Modern machipsandbob-4 working tools have ma mass production methods possible. 4ithoutthese tools, the life style we all take for granted would not exist. While being basically beneficial, in their u es, these machines are potentially hazardous. to the persons operating the . Safety, applied to procedures in a school or industrial environment, is often a matter of -common sense and good judgment.Mode"rn machinery is equippedwith.guardslanddevices designed to protect the 'operator and make- 'operating the equips nt as safe as possible. However, statistiEs.show that guards and otherlsa ety devices afford only 15% protection. Th.tS, 850 of Ilk all accidenti in school and industrial environmentsare due toa factor (or factors). that cannot bp guarded against by mechanlcal devices.Mast accidents are a result of so one's thoughtlessness, carelessness, lack of knowledge, . or lack of consider tion for the safetyof others, and these ,accidents may be avoided if worke s4Cquire the habit of thinkingbefore doing. .Safety is prin palli a matter, of learning and following, safepractices. and procedures at alh times. It ismuch more a,matter of do's thandon'ts. The basic text ofthis module prdvdes general machine information. Some specific 'practices and precautionsconcibed with the eff5cient operatioh' and use of most machine and woqdworking tools ingeneral use today:are also discussed. If these practi.ces and procedure are observed, then needless injuries and-equipment damage can be greatly reduced.

Modern. machind tools'are equipped with guards and devices designed to protect the operator and to make Operating the equipment as safe as possible. However; most accidents are,due to factors that cannot be guarded against by mechanical devices. Most accidents are the result of some person's thought- ,. lessnest, carelessness, laCk of knowledge, or lack of consideration, Nine . basic safety rules should be understood and observedby anyone operatimi'amy machine tool: These rules are 1-i-stq below: 1. Never start a machine if,the guard or guards have been removed or made inoperable as a result of a by, pass sSistent, 2. Avoid Wearing loose clothing.` "3', Never leave a running machine, unattended. 4. Wear proper eye protection. 14 5. Keep machine coolant clean and free,of debr.is. 6.

TABLESAW A large-capacity sliding table running next to the blade sets this saw apart from American- style cabinet saws. Less space, better machines Space savings aren’t the only ben- efit of European combination ma- chines. Each of the five individual tools will represent an upgrade for most small shops. 2.

PLANER of the lumber a furniture Combination machines also include maker encounters. a heavy-duty 12- or 16-in. planer. 52 FINE WOODWORKING W161CH.qxd 2/5/03 1:18 PM Page 53 ost American woodworkers know very little about European-style combination machines—except for their Mhigh price tags relative to other small-shop equipment. It has been 22 years since the last review of these machines in Fine Woodworking, so this article also provides a general introduction to them. I have defined combination machines as five-function, three-motor, heavy-duty units. The smaller multipurpose ma- chines such as the Shopsmith are a breed unto themselves. All of the machines covered include a sliding tablesaw, a shaper, a planer- jointer and an add-on horizontal mortiser with a sliding table. A real-world shop test. To try out each function as well as Six brands—Felder, Hammer, Knapp, MiniMax, Robland and Ro- the changeovers from one to the other, Chris- jek—are currently imported into North America, with a multitude tiana made a frame-and-panel door on each machine.

Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury. Indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury. Used without the safety alert symbol indicates potentially hazardous situation which, if not avoided, may result in property damage. SOME DUST CREATED BY POWER SANDING, SAWING, GRINDING, DRILLING, AND OTHER CONSTRUCTION ACTIVITIES contains chemicals known to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are: · lead from lead-based paints, · crystalline silica from bricks and cement and other masonry products, and · arsenic and chromium from chemically-treated lumber. Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment, always wear MSHA/NIOSH approved, properly fitting face mask or respirator when using such tools.

ABSTRACT A DEVELOPMENT AND MANAGEMENT MODEL FOR MODEL MAKING FACILITIES IN INDUSTRIAL DESIGN EDUCATION Tanrıverdi, Argun MDes, Department of Design Studies Supervisor: Asst.Prof.Dr. A.Can ÖZCAN May 2009, 170 pages The aim of this study is to create a model to help establishing a model making facility in an industrial design school from scratch or developing an existing model making facility. While creating the model, the study also aims to change the idea in people’s minds in Turkey about model making facilities (and any machine facilities) that has been established as a habitude or even worse, a culture. To achieve this aim, the study emphasizes the importance of health and safety with the highest priority, effective planning and management, and as much contribution of faculty members as possible, which means the distribution of the responsibility.
