CNC Machining Tool Paths Quiz for Middle School Students
Instructions: Select the BEST answer for each question. Think critically about the concepts of CNC machining!
1. What does a tool path represent in CNC machining?
A) The weight of the cutting tool
B) The programmed route a cutting tool follows relative to the workpiece
C) The color of the machine's paint
D) The speed of the machine's rotation
2. In turning operations, what is the primary goal of stock removal?
A) To make the workpiece heavier
B) To create decorative patterns
C) To reduce the diameter of a rotating cylindrical workpiece
D) To increase the machine's temperature
3. When a drill follows a "pecking cycle", what is its main purpose?
A) To create decorative holes
B) To improve chip evacuation and reduce tool wear
C) To make the drill move faster
D) To increase the hole's diameter randomly
4. Which technology helps generate tool paths based on 3D models?
A) CAD (Computer-Aided Design)
B) CAM (Computer-Aided Manufacturing)
C) GPS (Global Positioning System)
D) CPU (Central Processing Unit)
5. In threading, what synchronized movement creates the thread profile?
A) Random spinning of the tool
B) The tool follows a precise helical path synchronized with spindle rotation
C) The tool moves only vertically
D) The workpiece remains completely stationary
6. What is the primary motion in a drilling operation?
A) Horizontal movement
B) Circular rotation
C) Axial movement along the Z-axis
D) Random wandering
7. Why might a machinist use multiple passes when creating a thread?
A) To make the process more complicated
B) To gradually form the thread profile and achieve desired depth
C) To increase machine noise
D) To waste more material
8. In face grooving, what describes how the tool moves to create a groove?
A) The tool remains completely still
B) The tool moves radially inward or outward across the face
C) The tool spins randomly
