Bench Working and Cutting Tools

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.
