CNC Machine Program Simulator
An offline browser simulator for a documented subset of Siemens-style multi-axis NC commands and machine visualization.
MY FOCUSDeveloped parsing, state updates, animated toolpaths, configurable machine axes, and diagnostic logging.
ENGINEERING VALUE
Demonstrates manufacturing-domain software design with explicit safety boundaries.
ENGINEERING STUDY / CNCJS—02
Engineering concept illustration.
01 / THE PROBLEM
The engineering challenge.
NC programs need an accessible way to inspect axis motion and coordinate-transform intent before machine use.
02 / CONSTRAINTS
What the solution must consider.
- The simulator is not collision-certified, not a complete interpreter, and does not model OEM dynamics or controls.
03 / ENGINEERING APPROACH
Reasoning before geometry.
01
Engineering method
Parse only documented commands, make unsupported behavior explicit, and separate the machine configuration from program state.
02
Workflow features
Subset parser; Multi-axis state; AROT and transform handling; Animated toolpath; Machine configuration; JSONL diagnostics.
04 / DESIGN & IMPLEMENTATION
Connecting intent to execution.
The prototype progressed through the v11 development lineage with an interactive machine and toolpath interface.
- Subset parser
- Multi-axis state
- AROT and transform handling
- Animated toolpath
- Machine configuration
- JSONL diagnostics
05 / VALIDATION
The checks behind the design.
Prototype
The tool supports software exploration of machining sequences. It requires interpreter and motion checks for the selected NC dialect and provides no collision-certified machine verification.
06 / OUTCOME
The value of the work.
Demonstrates manufacturing-domain software design with explicit safety boundaries.
THE ENGINEERING PRINCIPLE
Make the process assumptions visible.
A plan or calculator is easier to trust when its units, quantity basis, setup assumptions and handoff documents are explicit. A numerical answer should be traceable to the inputs and method.
A question for a technical conversation
Which input changes the result most, and how would you compare the estimate with shop-floor observations?
