# Machine Simulation

Machine simulation shows **how the CNC machine moves** while executing a CAM program — not just where material is removed.

Instead of only displaying toolpaths in space, machine simulation visualizes:

* the machine structure
* the spindle and tool
* potential collisions and limits

This makes it possible to understand **how a program will run on the real machine**, not just what shape it will cut.

***

### Why machine simulation matters

Machine simulation helps you:

* see how the machine axes move during an operation
* identify potential collisions with fixtures, clamps, or the machine itself
* understand rotary axis behavior in **4-axis and 5-axis setups**
* verify that a setup is physically possible before running it

Especially in **5-axis work**, machine simulation helps confirm that the tool orientation is correct **in machine space**, not just mathematically valid.

Some orientations look identical in toolpath view but result in completely different machine motion.

In this way, machine simulation provides an important **reality check** between CAM planning and real machining.

Machine simulation helps you **understand and plan** how the machine will move.\
It can reduce surprises, but it does not replace careful physical setup.
