What is a best practice when updating CNC program documentation?

Always update the documentation immediately after changing the program. This keeps information accurate and avoids confusion.

What is the main benefit of adding comments in a CNC program?

A To reduce the number of tools needed

B To speed up the machine

C To explain the code for easier understanding

D To change the cutting speed automatically

Comments help people read and understand the program without changing how the machine works.

Which of the following should be included in CNC program documentation?

A Tool list and program description

B Machine brand and color

C Operator's personal details

D Weather forecast

Tool list and program description are important parts of CNC documentation to guide operation.

When should CNC program documentation be updated?

A Only when the machine breaks

B Never

C Once a year

D Immediately after program changes

Updating documentation right after changes keeps it accurate and useful.

How does good CNC documentation help with safety?

A By warning about special steps and limits

B By making the program run faster

C By reducing electricity use

D By increasing tool wear

Safety warnings in documentation help prevent accidents and damage.

What is NOT a reason to document a CNC program?

A To help others understand the program

B To make the program harder to read

C To record tool usage

D To explain special instructions

Documentation should make the program easier to read, not harder.
