Roadmap: FanucProgramManager

Overview

Console tool for CNC program transfer and file management. Fanuc FOCAS base, expanding to multi-CN (Heidenhain LSV2, Siemens FTP, Mitsubishi FTP) with NC program validation.

Current Milestone

v0.1 Multi-CN Release (v0.1.0) Status: ✅ Complete Phases: 5 of 5 complete Completed: 2026-05-13

Phase Details

Phase 1: cnc-abstraction ✅

Goal: Fix namespace, add all Cnc/ files to csproj, complete ICncMachine + IFanucMachine with 3-file support Completed: 2026-05-13

Delivered:

• Namespace Fanuc_integration.Cnc.* → FanucProgramManager.Cnc.* (29 files)
• IFocasDialect extended: UploadStart/DownloadStart accept short fileType
• IFanucMachine interface: extends ICncMachine with tool offset + work zero R/W
• CncManufacturer enum: Fanuc, Heidenhain, Siemens
• All 29 Cnc/**/*.cs files added to csproj

Phase 2: heidenhain ✅

Goal: Implement ICncMachine for Heidenhain TNC via LSV2 protocol Completed: 2026-05-13

Delivered:

• HeidenhainConnectionConfig — IP, port 19000, credentials, timeout
• Lsv2Client — TCP framing, CRC-16/CCITT, login (SELECT+LOG_IN), ReceiveFile/SendFile
• HeidenhainMachine : ICncMachine — RunGuardedAsync pattern, state machine

Phase 3: siemens ✅

Goal: Implement ICncMachine for Siemens Sinumerik via FTP Completed: 2026-05-13

Delivered:

• SiemensConnectionConfig — IP, port 21, creds, program dir /_N_MPF_DIR/
• SiemensFtpClient — FtpWebRequest wrapper, ASCII mode, passive
• SiemensMachine : ICncMachine

Bonus (post-apply):

• MitsubishiConnectionConfig / MitsubishiFtpClient / MitsubishiMachine : ICncMachine
• CncManufacturer.Mitsubishi added to enum + factory + CLI

Phase 4: program-wiring ✅

Goal: Wire all manufacturers into Program.cs + InputArgs Completed: 2026-05-13

Delivered:

• CncMachineFactory — creates right ICncMachine from InputArgs
• InputArgs — added manufacturer, username, password fields
• Program.cs — full rewrite using ICncMachine factory; Fanuc 3-file via IFanucMachine cast

Phase 5: nc-validator ✅

Goal: Per-manufacturer NC program validator runs inside WriteProgramAsync before upload Completed: 2026-05-13

Delivered:

• ValidationSeverity / ValidationError / ValidationResult model types
• INcProgramValidator + NcProgramValidator with universal + per-manufacturer rules
• Validator injected into all 4 machine classes
• NcProgramValidatorTests — 30+ NUnit tests

Next Milestone

v0.2 NcProgramManager (in progress) Status: Planning Phases: 0 of 4 complete

Phase	Name	Plans	Status
06	rename-cleanup	1	✅ Complete
07	license-core	1	Not started
08	license-integration	1	Not started
09	license-generator	1	Not started

Phase 06: rename-cleanup ✅

Goal: Rename FanucProgramManager → NcProgramManager (namespace, project files, test folder). Delete dead FANUCMachine.cs. Completed: 2026-05-17 Plans: [x] 06-01: Namespace + file rename

Phase 07: license-core (proposed)

Goal: IMachineFingerprint, ILicenseValidator, RSA signature verification, .lic file model Depends on: Phase 06

Phase 08: license-integration (proposed)

Goal: Wire license system into Program.cs, replace checkLicense, replace -chiave= with -licfile= Depends on: Phase 07

Phase 09: license-generator (proposed)

Goal: Separate generator console app — reads machine fingerprint, signs, writes .lic file Depends on: Phase 07
