Lesson 3: G-Code, M-Code, Motion, Compensation, Cycles, and Program Structure
Lesson Overview
This lesson develops practical skills in g-code, m-code, motion, compensation, cycles, and program structure for the CNC Programming Fundamentals Training course, with implementation, verification, documentation, and troubleshooting guidance.
Topics Covered
Program blocks, addresses, comments, modal commands, absolute and incremental modes
Rapid, linear and circular interpolation, planes, coordinates, spindle, coolant, and tool change
Tool length, radius, wear, nose-radius compensation, offsets, and corrective adjustment
Program reading, editing, syntax checks, subprograms, repetitions, and reusable code
Practical Activity
Create or review a practical configuration for program blocks, addresses, comments, modal commands, absolute and incremental modes.
Build and test an exercise involving rapid, linear and circular interpolation, planes, coordinates, spindle, coolant, and tool change and tool length, radius, wear, nose-radius compensation, offsets, and corrective adjustment.
Use diagnostics or evidence to validate program reading, editing, syntax checks, subprograms, repetitions, and reusable code.
Key Takeaways
Explain program blocks, addresses, comments, modal commands, absolute and incremental modes.
Apply rapid, linear and circular interpolation, planes, coordinates, spindle, coolant, and tool change and tool length, radius, wear, nose-radius compensation, offsets, and corrective adjustment.
Validate and troubleshoot program reading, editing, syntax checks, subprograms, repetitions, and reusable code.
