Engineering Study Guild

Drill press: used to drill accurate holes

• Safety: keep drill bits + machine clean

• Keep guards and clamps in place

• Lubricate the drill bit when drilling metal

• Support underside of the stock

Miter saw: used to cut straight lines and miter angles 

• Safety: respiratory protection, keep one hand at least 6 in away from blade

Table saw: used to cut straight lines + smooth cuts on small and long boards

• Cutting across = crosscut vs. with the good grain (rip)

• Safety: always use rip fence for rip cuts, use miter gauge for crosscuts, keep material completely flat against the table, make fence adjustments when power is off

Bandsaw: used to cut wood + metal stock

• Safety: keep hands at least 2 in from blade + never start the bandsaw w/ workpiece against the blade

• Hold workpiece firmly + feed it smoothly at a moderate speed

Spindle Sander: grinds stuff down w/ sandpaper at an angle and/or w/ a curve

• Safety: mark the workpiece, choose right drum size, attach sandpaper to the drum + use heavy globes and a dust mask 

Belt/ Disc Sander: disc sander is better for smaller projects where u need to remove material debris or to make outside curves, but belt’s main purpose is to shape, trim, level and sand larger projects

• Safety: use object u are trying to sand w/ two hards (one vertically at 45 degree angle and other horizontally against the object)

• For quick sanding, sand towards outer area of disc vs slower = towards inner area of disk 

Drum Sander: used to sand down large pieces or to finish multiple pieces of wood quickly

• Safety: roll up sleeves, tie hair, hearing protection, etc.

Def of engineering: branch of sci and technology concerned w/ design, building, and use of engines, machines and structures

Aeronautical: flight of all kinds of vehicles operating under different speeds and altitude

Agricultural: All systems + sciences for the production and processing of agricultural processes

Automotive: Design, build, + operate self-propelled vehicles (land or sea, in air or space)

Chemical: development of processes + design and operation of plants that materials undergo chemical changes during their manufacture

Civil: communication, transportation, construction, and manufacturing

Mechanical: machines, production of power + manufacturing methods

Computer Software: design, development, and maintenance of software systems + electronic devices

Electrical: application of electricity ranging from electric light + power systems to electronic appliances

Biomedical: combine mechanical eng w/ human anatomy and physiology

Nuclear: use and management of nuclear tech

Industrial: producing manufacturing systems
