Fusion 360 CAM and Manufacturing 1 — Questions and Answers
Question 1: In Fusion 360 CAM, what is a 'Setup'?
- Defines the stock material, machine, and work coordinate system for a machining operation (Correct answer)
- Loads tool library for a job
- Creates the G-code output file
- Defines the simulation speed
Correct answer: Defines the stock material, machine, and work coordinate system for a machining operation
A Setup specifies the raw stock shape, machine configuration, and origin point (WCS) that all toolpaths in that setup reference.
Question 2: What does '2D Adaptive Clearing' do in Fusion 360 CAM?
- Removes material efficiently in a planar region using trochoidal cutting motions (Correct answer)
- Drills holes at specified locations
- Profiles the outer edge of a part
- Finishes a flat floor with a single pass
Correct answer: Removes material efficiently in a planar region using trochoidal cutting motions
2D Adaptive Clearing uses a trochoidal (looping) tool motion to maintain constant tool engagement, removing pocketed material efficiently.
Question 3: What is the purpose of 'Post Processing' in Fusion 360 CAM?
- Converts the internal toolpath data into machine-specific G-code (Correct answer)
- Simulates the machining process
- Checks for tool collisions
- Defines the material stock
Correct answer: Converts the internal toolpath data into machine-specific G-code
Post processing translates Fusion 360's toolpath data into G-code formatted for a specific CNC machine using a post processor file.
Question 4: In Fusion 360 CAM, what does 'Stock' refer to?
- The raw block of material from which the finished part will be machined (Correct answer)
- The library of cutting tools
- The speed at which the spindle turns
- The simulated finished part
Correct answer: The raw block of material from which the finished part will be machined
Stock defines the initial block or shape of raw material that the CNC machine will cut away to produce the final part.
Question 5: Which Fusion 360 CAM operation creates a constant-depth pass around the boundary of a part?
- 2D Contour (Correct answer)
- 2D Pocket
- Bore
- Engrave
Correct answer: 2D Contour
2D Contour generates a toolpath that follows the outer profile of a part at a specified depth, cutting the boundary.
Question 6: What is 'Cutting Feedrate' in Fusion 360 CAM?
- The speed at which the tool moves through the material during a cut (Correct answer)
- The speed at which the spindle rotates
- The depth of each cutting pass
- The tool's diameter used for cutting
Correct answer: The speed at which the tool moves through the material during a cut
Cutting feedrate is the linear speed (typically in mm/min or in/min) at which the tool advances through the material.
