[step-manufacturing] Minutes of the Baltimore meeting

[Martin Hardwick]

All,

Please see the minutes of the Baltimore meeting below (and also on the 
ftp site).

The most important result of the meeting was the promotion of our team 
to be a Joint Working Group 15 for Digital Manufacturing.

We had a very good industry day and I thank all the speakers.

The presentations made on that day are on our new ftp site which should 
be much faster and more accessible than the old site
ftp://downloads.steptools.com/private/JWG15/Baltimore

These minutes and the attached meeting summary are also on the site. An 
attendee list is in the summary.

  Joint Working Group for Digital Manufacturing


  Baltimore Meeting – October 19 to 22


    Overview

The Joint Working Group for Digital Manufacturing was formed as Working 
Group 15 of TC184/SC4 at this meeting. The scope of the new working 
group is as follows:


/To identify and where necessary develop a coherent set of Industrial 
Data Standards maximizing efficiency for the realization of digital 
products including the areas of digital control, digital planning, 
digital monitoring, digital simulation, digital validation and digital 
inspection, in full cooperation with other standards development 
organizations.

The thesis of digital manufacturing is that if all the necessary 
information can be made available to shop floor controls then that next 
generation of manufacturing systems can be made more intelligent and 
efficient. Building the solution onto the STEP standards allows the 
design requirements to be transmitted to the floor in a semantic form 
where it can be processed by intelligent applications. The mission of 
JWG15 is to supplement these requirements with manufacturing solution 
information to enable *semantic manufacturing*. It will do so by 
publishing definition modules that add new functionality to the digital 
product data described by STEP, and by publishing technical reports to 
explain how to build models for manufacturing resources and processes so 
that applications can behave intelligently on the shop floor.


    Purpose of this meeting

The purpose of this meeting was to examine the development of new cloud 
services for machining and what standards and technical reports may be 
necessary to enable the wide deployment of these services. Three 
services were discussed during the technical sessions and on an Industry 
data hosted by the working group on Wednesday, October 21.

·The Virtual CMM service. A Coordinate Measurement Machine that predicts 
machining results by measuring machining simulations for conformance to 
the GD&T of a product model.

·An NC Generation Service. A service that uses ACIS and Mastercam to 
generate machining solutions from as-is and to-be models of the part.

·A 3D Process Monitoring service. A service that enables the 
visualization and validation of process data on tablets and phones.


    Action Items

The following action items were taken during the meeting.

·David Loffredo to define a template for WG15 Technical Reports.

·Mikael and David O to write implementation guidelines for AP242 
machining resource models includingdefinition of kinematics and the 
interface between the cutting tool and the machine (gauge line, etc.) as 
a technical report.

·Bengt Olsson and Martin Hardwick to write implementation guidelines for 
requesting tooling solutions and making tooling recommendations in the 
context of a process.

·Mikael and Leon to write AP242 implementation guidelines for the 
spindle characteristic curves and the tool holder interface.

·Mikael and David O to write AP242 implementation guidelines and schema 
module for describing the motion error tolerance of a machine tool.

·Mikael Hedlind and Magnus Lundgren to write implementation module and 
implementation guidelines for key characteristics

·Mikael Hedlind and David Loffredo to write implementation guidelines 
for data exchange of non-cnc processes such as painting, washing, hardening

·David Loffredo to update the technical corrigendum documentation

·Martin Hardwick to investigate implementation of a conditional workplan

·STEP Tools to develop exemplar modules for toolpath and executable.


    Meeting Summary

The following other items and outcomes from the meeting may be of interest.

·Two DMDII projects have been funded to develop the three services; 
DMDII 14-02-02 “Mind the Gap” has been operating since July. DMDII 
14-06-05 is in negotiation with a January start anticipated.

·Agreement has been reached between the cutting tool vendors and the 
cutting tool users on a standard for packaging tooling information as 
information packets containing ISO 13399 data.

·APQP quality assurance requirements will be added to the new edition so 
that the key characteristics of a manufacturing solution can be 
identified for risk mitigation by the supply chain.

·Sandvik has made ISO 13399 data for 53,000 tools.

·Edition 3 of the file format used by STEP is now ready for publication. 
This edition includes the ability to divide very large data sets into 
multiple files linked by http references and anchors, to digitally sign 
data sets to assure against tampering and to authenticate ownership, and 
to identify key characteristics in a model using Universally Unique 
Identifiers (UUIDs) so that they can be referenced from other kinds of data.
