This teleaula covers the process of fresagem, explaining its mechanics and the types of movements involved. It introduces various types of fresadoras and provides guidelines for selecting the appropriate fresa for different operations. The session concludes with a review of the key concepts discussed.

What is the main advantage of using a milling machine?

• It can only work with flat surfaces.

• It is slower than other machining processes.

• It is only used for non-metallic materials.

• It can machine almost any piece and surface of all types and shapes.

What are the two movements involved in the milling process?

• Rotation of the tool and movement of the machine base.

• Rotation of the tool and movement of the workpiece table.

• Movement of the machine base and the workpiece table.

• Rotation of the workpiece and the machine base.

What is the main issue with the concordant movement in milling?

• It causes the machine to stop frequently.

• It makes the machine overheat.

• It leads to irregular table movements and poor finish.

• It increases the wear on the cutting tool.

How are milling machines classified based on the spindle orientation?

• Horizontal, vertical, and universal.

• Manual, automatic, and CNC.

• Single-axis, dual-axis, and multi-axis.

• Small, medium, and large.

What is a unique feature of a universal milling machine?

• It has both horizontal and vertical spindles.

• It can only machine flat surfaces.

• It has a single spindle.

• It is used only for copying operations.

What is the primary function of a pantograph milling machine?

• To cut non-metallic materials.

• To machine large surfaces quickly.

• To copy a specific model manually.

• To perform high-speed drilling.

Which material is recommended for making models when only a few copies are needed?

• Bronze

• Resin

• Aluminum

• Steel

What is a key characteristic of a milling cutter with a smaller wedge angle?

• It is more resistant and used for hard materials.

• It is less resistant and used for non-ferrous materials.

• It is used for high-speed operations.

• It is only used for finishing operations.

Which type of milling cutter is used for machining key slots and T-slots?

• Face milling cutter

• Angular milling cutter

• End milling cutter

• Slotting cutter

What is the advantage of using insert-type milling cutters?

• They are only used for roughing operations.

• The inserts can be replaced when worn out.

• They can be used for any material.

• They are cheaper than solid cutters.
