Machine Tool Managment Protocol (MTMP)

Machine Tool Managment Protocol is a HTTP based protocol used to interface with common functions for managing Machine Tools such as Load Program, Set Tool Offset, Set Variable, etc.

Purpose

To provide a common HTTP based interface for Loading Programs, Setting Tool Offsets, etc. on a Machine Tool.

Functions

Load NC Program
- POST (/Machine01/program)
  - Request Body = NC Code File Contents
Set Active NC Program
- PUT (/Machine01/program/activate?id=EXAMPLE01.NC)
Set Tool Offset
- POST (/Machine01/tooloffset/14)
  - Request Body = Tool Offset JSON (see below)
Set Variable
- PUT (/Machine01/variable/5601?value=56.123)

Authorization

API Tokens are generated on the MTMP Broker and configured for a specific Machine Connection. A client can then use this API Token to send requests and the Broker can verify that the Client is authorized to make the request.

Broker

The broker is responsible for hosting the web server used to accept Function Requests. It is also used to host the Adapters that communicate with the machine tool's API.

Adapter

The Adapters are used to communicate with the specific machine tool API. An example would be a Fanuc Adapter that communicates using the Fanuc FOCAS API.

Tool Offsets JSON

Below is a draft of what the format should be. Many variations could be possible but most should have a Length and Diameter (in Millimeters). Possibly need to add multiple Lengths (ex. X, Y, Z) and also may need to add a way to send Tool Life info.

{
  "id": "12",
  "description": "An example Tool Offset for Tool #12 with a Length=125.456 and a Diameter=12.002",
  "length": 125.456,
  "diameter": 12.002
}
