Fusion 360 CAM and Manufacturing 2

Question 1

In Fusion 360 CAM, what does 'Spindle Speed' (RPM) control?

Accepted Answer

How fast the cutting tool rotates

Answer

Spindle speed sets the rotational speed of the cutting tool in revolutions per minute, affecting surface finish and tool life.

Question 2

What is 'Stepover' in Fusion 360 CAM milling operations?

Accepted Answer

The lateral distance between adjacent toolpath passes

Answer

Stepover is the horizontal distance between adjacent parallel passes, controlling the amount of material left between cuts (scallop height).

Question 3

Which Fusion 360 CAM strategy is best for finishing a complex 3D sculpted surface?

Accepted Answer

3D Scallop or Parallel finishing

Answer

3D finishing strategies like Scallop or Parallel maintain a consistent scallop height across complex 3D surfaces for smooth results.

Question 4

What is a 'Tool Library' in Fusion 360 CAM?

Accepted Answer

A database of cutting tools with defined geometry and cutting parameters

Answer

The Tool Library stores definitions of cutting tools — including diameter, flute count, and speeds/feeds — for reuse across operations.

Question 5

What does 'Depth of Cut' (axial depth) define in Fusion 360 CAM?

Accepted Answer

How deep the tool cuts into the material per pass

Answer

Axial depth of cut is how far the tool plunges into the material vertically in a single pass, affecting cutting forces and chip load.
