Study Notes

Bench Work Tools and Techniques

Gauges are essential for precision measurement and ensuring accuracy in dimensions during bench work.
A curved chisel, known as a 'gooseneck chisel,' is specifically designed for cutting curves in metal.
Scrapers serve to smooth and finish surfaces, removing small amounts of material to achieve a desired finish.
A flat file is typically used for sharpening cutting tools due to its coarse surface ideal for material removal.

Measuring Instruments

The 5S method in the automotive industry focuses on organizing and maintaining a clean workspace to improve efficiency and reduce waste (Sort, Set in Order, Shine, Standardize, Sustain).
Lock Screws in Vernier Calipers secure the sliding jaws in position for stable measurements.
A Vernier Caliper's main scale is generally calibrated in millimeters and inches for accurate measurement.
High-carbon steel is characterized by its high iron and carbon content, enhancing hardness and wear resistance.
Malleable metals, like aluminum or copper, can be shaped without breaking, making them useful in various applications.
The Depth Rod on a Vernier Caliper measures the depth of holes or recesses accurately.
The Vernier Scale on a Vernier Caliper typically displays measurements in tenths of a millimeter or fractional inches.

Machinery Functions

The primary function of a Twist Drill is to create round holes in various materials using rotational cutting.
The Flute in a Twist Drill serves to remove chips and debris produced during drilling, improving efficiency.
High-Speed Steel (HSS) drill bits offer superior hardness and heat resistance, allowing for faster drilling without dulling.
A Lathe Machine is utilized for shaping and formulating parts by rotating the workpiece against stationary cutting tools.
The Carriage on a Lathe Machine holds the cutting tool and moves it along the workpiece for shaping operations.
CNC Lathes provide automation, increased precision, and the ability to produce complex shapes with minimal operator input.
The primary function of a Shaper Machine is to create flat or contoured surfaces by moving a tool back and forth across the workpiece.
The Ram on a Shaper Machine contains the cutting tool and facilitates the shaping action through its linear motion.
A Vertical Drilling Machine is primarily used for drilling vertical holes into materials, often providing more stability.
CNC Drilling Machines enhance drill speed and accuracy while allowing for complex programming of drilling patterns.
