Study Notes
Milling Machine Quiz - Study Notes
- Milling Machine Function: Primary function is machining solid materials using a rotating cutting tool.
- Milling Machine Foundation: The base is the foundation, housing the column.
- Spindle Purpose: The spindle transmits power to the arbor, guiding table movement.
- Arbor Function: The arbor supports the workpiece and rotates the cutting tool.
- Vertical Movement: The saddle allows vertical movement.
- Horizontal vs. Vertical Milling Machines: Distinguished by the orientation of the spindle.
- End Milling Purpose: Used for machining flat or contoured surfaces on a workpiece.
- Angled Edge Operation: Chamfer milling creates an angled edge on a workpiece.
- Hole Diameter Enlarging: Reaming or boring enlarges a hole's diameter.
- Thread Creation Tool: A tap creates internal threads.
- Cutting Speed Measurement: Cutting speed measures the speed of the workpiece relative to the tool.
- Surface Roughness Causes: Too low a feed rate, incorrect cutting parameters, or a dull cutting tool may cause surface roughness.
- Workpiece Clamping Issues: Insufficient clamping can cause vibrations or inaccurate cuts.
- Feed Rate Definition: The feed rate is the speed of the tool's movement relative to the workpiece.
- Rotary Table Function: Rotates the workpiece for smooth finishing.
- Dividing Head Function: Dividing head provides uniform division of the workpiece's periphery.
- 3D Contoured Shape Cutter: A ball nose cutter is best suited for machining 3D contoured shapes.
- Face Mill Advantages: A face mill efficiently machines flat surfaces.
- Flute Purpose: Flutes on a cutter reduce friction and remove chips.
- Coolant Use: Coolant reduces cutter temperature and friction during milling operations.
- Cutter Material: High-speed steel is a common material for cutters.
- Broad Flat Surface Tool: A roughing end mill or slab mill is best for creating broad, flat surfaces.
- Rack Milling Attachment Function: Creates rack teeth, helical grooves, or contoured surfaces.
- Rapid Material Removal Cutter: A slot drill or similar cutter with wavy teeth is used for rapid material removal.
- Vise Function: The vise secures the workpiece.
- Hollow Mill Feature: Hollow mills have cutting teeth on their inner surface.
- Burn Marks Cause: Low spindle speeds, incorrect depth of cut, or insufficient clamping can lead to burn marks.
- Internal Keyway Attachment: A slotting attachment is used for machining internal keyways.
- Tool Lifetime/Wear Rate Parameter: Axial depth of cut is a significant factor.
- Carbide Cutter Coating: Coating improves wear resistance and cutting speed.
- Keyway Slot Tool: A slot drill is ideal for creating keyway slots.
- Hole Enlarging Operation: Reaming or boring uses single-point cutting tools for enlarging drilled holes.
- Purpose of Fly Cutter: A fly cutter is used for creating wide, shallow cuts and milling 3D contoured shapes.
- Excessive Vibration Cause: Excessive vibration leads to surface roughness, inaccurate dimensions, and scratch marks.
- Cone-Shaped Opening Tool: Counterboring or countersinking creates cone-shaped openings.
- Machinability Material: Certain materials, like aluminum, have good machinability.
- Workpiece Material Selection Factor: Machinability is a critical factor for selecting the workpiece material.
