Fusion 360 CAM and Manufacturing 2 — Questions and Answers
Question 1: In Fusion 360 CAM, what does 'Spindle Speed' (RPM) control?
- How fast the cutting tool rotates (Correct answer)
- How fast the tool moves through the material
- The depth of cut per pass
- The number of toolpath passes
Correct answer: How fast the cutting tool rotates
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?
- The lateral distance between adjacent toolpath passes (Correct answer)
- The depth the tool descends per pass
- The distance the tool retracts before repositioning
- The overlap between ramp entry passes
Correct answer: The lateral distance between adjacent toolpath passes
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?
- 3D Scallop or Parallel finishing (Correct answer)
- 2D Contour
- Drill
- 2D Pocket
Correct answer: 3D Scallop or Parallel finishing
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?
- A database of cutting tools with defined geometry and cutting parameters (Correct answer)
- The physical toolholder setup on the machine
- A list of G-code post processors
- A history of all toolpaths created
Correct answer: A database of cutting tools with defined geometry and cutting parameters
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?
- How deep the tool cuts into the material per pass (Correct answer)
- The horizontal width of each pass
- The total material to be removed
- The tool's total cutting length
Correct answer: How deep the tool cuts into the material per pass
Axial depth of cut is how far the tool plunges into the material vertically in a single pass, affecting cutting forces and chip load.
Question 6: In Fusion 360 CAM, what is a 'Toolpath Simulation'?
- A visual preview showing the tool cutting through stock to verify the machining result (Correct answer)
- A test of the machine's mechanical motion
- A collision check between fixtures
- A rendering of the finished part surface
Correct answer: A visual preview showing the tool cutting through stock to verify the machining result
Toolpath simulation animates the cutting tool removing stock material, allowing you to detect gouges, collisions, or missed areas before running the machine.
