Preview Questions Tool and Die Maker | Role Specific Skill

Question 1: What tool maintenance activity is essential when ensuring proper alignment and balance in rotating cutting tools?

Which action should you take?

Choose only one option

Balancing the tool to prevent vibration

Lubricating the tool during operation

Coating the tool with anti-wear material

Sharpening the cutting edges

Question 2: What is the function of the "G28" code in CNC programming?

Which action should you take?

Choose only one option

To home the machine to its machine zero position

To engage the spindle for cutting operations

To initiate tool calibration

To trigger automatic tool change

Question 3: In blueprint reading, what does a dashed line typically represent?

Which action should you take?

Choose only one option

Centerline of symmetry

Hidden or non-visible edges

Projection lines

Cutting plane line

Question 4: How does "CNC tool path optimization" reduce cycle time and improve production efficiency?

Which action should you take?

Choose only one option

It tracks only final outcomes, ignoring the role of optimized tool paths in reducing cycle time

It optimizes the tool movement to minimize unnecessary motion and improve machining speed

It reduces the need for optimization by assuming that all tool paths are equally efficient

It speeds up programming by ignoring optimization and focusing only on basic movements

Question 5: When inspecting a tool for wear, which sign is commonly associated with impending tool failure?

Which action should you take?

Choose only one option

A sharp reduction in cutting efficiency and excessive heat generation

The tool becoming visibly heavier due to material build-up

A slight change in the tool's color

An increase in vibration during operation

Question 6: How does "helical interpolation" improve machining performance in CNC programming?

Which action should you take?

Choose only one option

It tracks only linear cuts, ignoring the precision and efficiency gained through helical interpolation

It creates smooth circular tool paths for precise milling and drilling, reducing tool wear and improving accuracy

It speeds up programming by ignoring interpolation techniques and focusing only on linear tool paths

It reduces the need for helical interpolation by assuming that straight-line tool paths are sufficient
