|
## Project Reference
|
|
|
|

|
|
|
**Core value:** Machinists transfer CNC programs to/from any controller without manual steps or internet

|
|
|
|

## What Was Built (v0.1 Multi-CN Release)
|
|
|
|
### Phase 1 — CNC Abstraction
|
|
- Namespace: `Fanuc_integration.Cnc.*` → `FanucProgramManager.Cnc.*` (29 files)
|
|
- `IFocasDialect` extended: `UploadStart`/`DownloadStart` accept `short fileType`
|
|
- `IFanucMachine` created: extends `ICncMachine` with tool offset + work zero R/W
|
|
- `CncManufacturer` enum: Fanuc, Heidenhain, Siemens, Mitsubishi
|
|
- All 29 `Cnc/**/*.cs` files added to csproj
|
|
|
|
### Phase 2 — Heidenhain LSV2
|
|
- `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 + Mitsubishi FTP
|
|
- `SiemensConnectionConfig` / `SiemensFtpClient` / `SiemensMachine : ICncMachine`
|
|
- `MitsubishiConnectionConfig` / `MitsubishiFtpClient` / `MitsubishiMachine : ICncMachine`
|
|
|
|
### Phase 4 — Wiring
|
|
- `CncMachineFactory` — creates right `ICncMachine` from `InputArgs`
|
|
- `InputArgs` — added `manufacturer`, `username`, `password` fields
|
|
- `Program.cs` — full rewrite using `ICncMachine`; Fanuc 3-file via `IFanucMachine` cast
|
|
|
|
### Phase 5 — NC Validator
|
|
- `ValidationSeverity` / `ValidationError` / `ValidationResult` model types
|
|
- `INcProgramValidator` + `NcProgramValidator` (5 universal + per-manufacturer rules)
|
|
- Validator injected into all 4 machine classes; upload blocked on Error severity
|
|
- `NcProgramValidatorTests` — 30+ NUnit tests
|
|
|
|
### Test Infrastructure
|
|
- `NcProgramManager.Tests/` — NUnit 3.13.3 + Moq 4.18.4, .NET 4.7.2
|
|
- `FtpServerStub` + `Lsv2ServerStub` — in-process TCP stubs
|
|
- Unit + integration tests; Fanuc FOCAS tests `[Ignore]`d (Windows-only DLL)
|
|
|
|
## What Was Built (v0.2 NcProgramManager — in progress)
|
|
|
|
### Phase 06 — Rename Cleanup
|
|
- Namespace: `FanucProgramManager.*` → `NcProgramManager.*` (all files)
|
|
- Project renamed, test folder renamed, dead `FANUCMachine.cs` deleted
|
|
|
|
### Phase 07 — License Core
|
|
- `IMachineFingerprint` / `ILicenseValidator` interfaces
|
|
- `MachineFingerprint` — WMI CPU/BIOS fingerprint, SHA256 hash
|
|
- `LicenseFile.TryRead` — reads `.lic` file, returns base64 signature
|
|
- `LicenseValidator.Validate` — RSA-SHA256 verify; PLACEHOLDER public key until Phase 09
|
|
- `LicenseValidatorTests` — 6 unit tests (testable via internal ctor injection)
|
|
|
|
### Phase 08 — License Integration
|
|
- `Program.cs` — `checkLicense` deleted; RSA check wired at startup:
|
|
```csharp
|
|
string _licPath = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "license.lic");
|
|
if (!LicenseFile.TryRead(_licPath, out _licBase64)
|
|
|| !new LicenseValidator().Validate(_licFingerprint, _licBase64)) { ... }
|
|
```
|
|
- `InputArgs.cs` — `chiave` field removed
|
|
- `-chiave=` CLI arg removed; license file hardcoded next to EXE as `license.lic`
|
|
- `MostraAiuto` updated: instructs user to place `license.lic` next to executable
|
|
|
|
## CLI Args (current)
|
|
- `-manufacturer=fanuc|heidenhain|siemens|mitsubishi` (default: fanuc)
|
|
- `-azione=` — action (Scarica/Invia/etc.)
|
|
- `-ip=` — CNC IP
|
|
- `-porta=` — port
|
|
- `-username=` (Heidenhain/Siemens/Mitsubishi)
|
|
- `-password=` (Heidenhain/Siemens/Mitsubishi)
|
|
- License: place `license.lic` next to the EXE (no CLI arg)
|
|
|
|
## Accumulated Context
|
|
|
|
### Decisions
|
|
- .NET 4.7.2 locked — max compatibility
|
|
- RSA asymmetric offline licensing: private key vendor-only, public key embedded in binary
|
|
- `license.lic` always at `AppDomain.CurrentDomain.BaseDirectory` — no CLI override
|
|
- `RSACryptoServiceProvider` + `SHA256CryptoServiceProvider` (not HashAlgorithmName) — .NET 4.7.2 compat
|
|
- Constructor injection pattern: internal ctor accepts key XML — testable without Windows WMI
|
|
- PublicKeyXml = PLACEHOLDER until Phase 09 generates real key pair
|
|
- Heidenhain: LSV2 port 19000, needs real hardware testing
|
|
- Siemens: FTP `/_N_MPF_DIR/`, needs Sinumerik FTP option enabled on machine
|
|
- `#` = Warning in Fanuc/Mitsubishi — macro variable indicator
|
|
|
|
### Deferred Issues
|
|
- Real RSA key pair — Phase 09 output; copy PublicKeyXml into LicenseValidator.cs
|
|
- `AesCrypt.cs` dead code — remove in future cleanup phase
|
|
- Heidenhain: `ReadActiveProgramAsync` / `SelectMainProgram` not implemented
|
|
- Siemens: same as Heidenhain
|
|
- Build + integration not verifiable on Linux (fwlib32 Windows-only)
|
|
- MachineFingerprint WMI — code-review verified, needs real Windows hardware test
|
|
|
|
### Blockers/Concerns
|
|
None — Phase 09 can start.
