Study Notes

Manufacturing Steps

Three major steps: obtain natural resources, produce industrial materials, make finished products.

Machining Operations

Non-machining operations include any processes not utilizing machines.

Stock Specification

Very thin stock is specified by gauge numbers.

Band Saw Uses

Band saws perform three main functions: cut metal stock into shorter pieces, conduct rough cuts, and follow complex curves/patterns.

Horizontal Band Saw

Features a blade that forms a continuous loop to cut material.

Vertical Band Saw

Capable of cutting intricate curves and patterns in workpieces.

Safety Rules Around Machine Tools

Always wear safety glasses.
Avoid loose clothing.
Remove jewelry like ties, watches, and rings.
Secure long hair.
Wear heavy-duty, preferably steel-toed, shoes; canvas shoes are unacceptable.

Blade Guides for Vertical Band Saw

Set guides 3/8 to ½ inch above the stock's thickest point and no more than ½ inch above the workpiece's highest point.

Machine Safety Protocol

If a blade breaks or disengages, immediately turn off the machine.

Cutting Tools

Horizontal band saw is primarily used to cut raw stock into shorter lengths.

Layout Work

Involves transferring data for machining operations.

Drill Press Function

Mainly used to create holes in various materials.

Tool Condition

Worn drilling tools should not be used to ensure safety and accuracy.

Unsafe Practices with Drill Press

Unsafe actions include standing beside the drill press, stopping the spindle with hands, and allowing distractions during operation.

Twist Drill Components

Parts include the shank, body, point, web, and tang.

Lubrication in Drilling

Lubricants are applied where the drill penetrates the material.

Drill Press Setup Safety

Improper mounting of the workpiece is an example of unsafe practice.

Reamers

Defined by multiple cutting edges for precise hole finishing.

Countersinking

Achieves a cone-shaped opening at the top of a drilled hole, allowing flathead screws to sit below the surface.

Counterbore Functionality

Enlarges holes to a specific depth for fittings.

Counterbore Tool

Characterized by having a pilot for precise hole enlargement.

Taps

Resemble screws and are used to create internal threads in holes.

Chamfer Hole Purpose

Enlarges the hole's opening to facilitate tap insertion.

Reamers' Capabilities

Used to drill holes to precise sizes, remove minimal material, and smooth the hole's interior.
