CNC Online Checker

Purpose-built for CNC programming teams, the tool analyzes G-code to validate syntax, modal state, and unit consistency. It highlights unsafe moves, over-travel risks, and unusual feed rates, offering concrete patch suggestions. The analysis is language-agnostic, focusing on widely adopted FANUC/Haas dialects and ISO 6983 conventions. Beneficiaries include shop-floor technicians and pre-production engineers seeking rapid feedback before running jobs.
Conceptually, the tool parses the program into blocks, maintains a state machine for modal groups, and cross-checks line-by-line with domain rules. It estimates basic execution time from travel moves and feeds, enabling early scheduling insights. The result is a structured report with line references, severity levels, and remediation notes, plus an option to patch the code automatically or export a corrected version for review.
Key differentiators include controller-dialect awareness, explicit safety checks, and a patch-assisted workflow that reduces rework. Typical use cases include validating a new complex pocketing routine, auditing post-processor outputs, and conducting a quick QA pass on a batch of programs before production runs.
