What is the purpose of setting the stock origin point?
It tells the machine where the stock's reference point is, so all machining coordinates are correct.

What does 'stock' refer to in CNC programming?
✗ Incorrect
Stock is the raw material block from which the part is made.
Why must the stock size be defined before machining?
✗ Incorrect
Defining stock size helps avoid crashes and allows correct toolpath planning.
Which is NOT a common way to define stock?
✗ Incorrect
Tool diameter is unrelated to defining stock size.
What does setting the stock origin point do?
✗ Incorrect
Stock origin sets the reference point for all machining coordinates.
How does proper stock setup help toolpath generation?
✗ Incorrect
Knowing stock boundaries helps generate safe toolpaths avoiding collisions.
Explain what 'stock' means in CNC programming and why it is important to define it before machining.
Think about the raw material and how the machine needs to know its size.
