# Philips CNC6600 NC System Interpreter

## Description

This is an interpreter for programs written for the MAHO MH-C 700.  
It basically creates a state-machine that represents the Philips CNC6600 NC system.  

## Requirements

- `PHP7.4`
- `composer` ([get it here](https://getcomposer.org/download/))

## Usage

### Installation
```bash
## install dependencies and autoloader
$ composer install

## copy tool configuration data and edit it 
$ cp config/tools.yaml.dist config/tools.yaml
$ nano config/tools.yaml
```

### Tool data

Tools are loaded from `config/tools.yaml`.  
A tool configuration example would be:

```yaml
# config/tools.yaml

T1:
  X: 5500 # radius in 0.001mm
  Z: 2500 # length in 0.001mm

T2:
  X: 3000
  Z: 61379
```

### Programs

The application loads programs from `config/part_programs` and `config/sub_programs`.  
The programs are stored in the memory of the machine.  

- A file containing a program _may_ have any name (a program is identified by its program number)
- A program _must_ have a program number as the first block
- A program is terminated either by a comment containing 'EOF' (case sensitive) or by a physical EOF
- A comment is denoted by `;`, anything after this character on the same line is ignored

An example of a program would be:

```text
; config/part_programs/some_name

;; Some program that drills two holes
N9045

; and yes, comments are fully supported,
; or rather, detected and ignored by the parser
N10 G18 T2    M6
N20 G1  F1500 S1250
N30 M4

; prepare and execute drill cycle
N40 G81         Y2000   Z-7000   B48000

; the parser also understands this
N50G79X-20000Y0Z-15000

; hell, you may even put multiple blocks on one line:
; N50G0X2N60G1Y20
; though it's good practice to align your program:
N60 G79 X20000  Y0      Z15000

N70 G0 Y150000  ; safely retract
N80 M2          ; turn off spindle, no return

;; EOF
```
  
Executing program `9045` from the example:
```bash
## execute the example program
$ bin/run_program 9045

## or
$ php bin/run_program 9045
```

- calling a subprogram (`G22 X9...`) is supported
- line repetitions (`E0302`) are _not_ supported yet
- parameter programming is _not_ supported yet

### Machine State

The machine state can be saved to a file to continue later on by using `State\Persister`.  

```php
use Machine\CNC6600;
use State\Persister;

$CNC6600 = new CNC6600();

// Do some things with the machine...

// Saving the machine state
$persister = new Persister();
$persister->persist('some_state_identifier', $CNC6600);

// Retrieving the saved state
$CNC6600 = $persister->load('some_state_identifier');
```

## Future

- Tool path simulation
- Manual Data Input (_MDI_) mode
- Proper tool compensation
- Line repetitions
- Parameter programming
