1. Cutting Tool Representation

We have two cutting tools from two vendors (Sandvik and ISCAR) each 
using the same representation. The first cutting tool includes geometric 
construction data, associative tolerance data and semantic tolerance data.

The second cutting tool uses the same type of representation to describe 
a series of mounting points for its data inserts.

The high degree of commonality between the two representations (each 
made in different CAD systems) is highly encouraging and we will try to 
organize a meeting in Stockholm to reach agreement on how to represent 
cutting tool data in AP-242.


2. June Demonstration

We have made our first test data for the Stockholm demonstration.

You can view this data using the STEP-NC Explorer software - available 
at no charge for testing purposes at

The manufacturing operations were programmed in Mastercam. The workpiece 
and fixtures were designed in NX.  The team is encouraged to view the 
data and make suggestions for future iterations.

The next telecon will be held on Wednesday April 18th at the regular 
times. A recording of this meeting is at the following ftp site
