3: Machining

Question 1

Milling/Routing - Definition

Answer 1

Uses rotary cutters to remove material from a workpiece by advancing in a direction at an angle with the axis of the tool

Question 2

Drilling - Definition

Answer 2

Used to create round holes in a workpiece using a rotating drill bit.

Question 3

Turning - Definition

Answer 3

Where a cutting tool removes material from the external surface of a rotating workpiece to shape it.

Question 4

Stamping - Definition

Answer 4

Uses a press to form or cut metal sheets into specific shapes.

Question 5

Pressing - Definition

Answer 5

Uses a press to apply pressure to a material, deforming it to create a specific shape.

Question 6

Milling/Routing - Process

Answer 6

1. The workpiece is fixed on a table and fed against a rotating cutter.
2. The cutter removes material to form the desired shape.
3. The movement can be either vertical or horizontal.

Question 7

Drilling - Process

Answer 7

1. The drill bit is mounted on a spindle and rotated at high speed.
2. The workpiece is clamped, and the drill bit is fed into the material, cutting away material to form a hole.

Question 8

Turning - Process

Answer 8

1. The workpiece is clamped onto a lathe and rotated at high speeds.
2. A cutting tool is then moved linearly along the surface of the workpiece, removing material to create the desired shape.

Question 9

Stamping - Process

Answer 9

1. The metal sheet is placed on a stamping press where a die shapes or cuts the metal with a single or series of high-pressure strikes.
2. Stamping can include operations like punching, blanking, embossing, and coining.

Question 10

Pressing - Process

Answer 10

1. The material is placed between two halves of a mold or die, and pressure is applied via a press machine.
2. This can involve cold pressing, where the material is shaped at room temperature, or hot pressing, where heat is applied to aid the forming process.

Question 11

Milling/Routing - Examples

Answer 11

Creating slots, grooves, and complex three-dimensional shapes on parts such as engine components and molds.

Question 12

Drilling - Examples

Answer 12

Producing holes for fasteners like screws and bolts in manufacturing and construction.

Question 13

Turning - Examples

Answer 13

Manufacturing cylindrical components such as shafts, bolts, and pulleys.

Question 14

Stamping - Examples

Answer 14

Producing automotive body panels, metal enclosures, and household appliances.

Question 15

Pressing - Example

Answer 15

Forming metal components like car parts, electronics enclosures, and packaging materials
