We discussed how to use STEP-NC, ISO 13399 and a Machine Tool Model 
to estimate the power required to make a part on a particular 
machine. Papers written by the University of Bath and the University 
of Stuttgart have been put onto the ftp site.

The consensus was that a power consumption estimator would be a good 
pilot project for the meeting after Bath. The spreadsheet prepared by 
Sandvik showing where data is located in the three standards is a 
good starting point for the project.

Boeing will add cutting cross section data to the Moldy data set so 
that the power consumption pilots can compute how much material is 
being removed on each tool path.

We discussed the Boxy part. The STEP-NC Explorer now has an interface 
that lets users create setups and move workingsteps between 
workplans. There are still some issues with some aspects of the user 
interface and the code generators do not output the correct codes for 
setups yet. This is being fixed and the latest version (7.26) 
contains the first version of the new generators.

KTH is preparing versions of the Boxy part for 3-axis Hardinge and 
Mazak machines and a Tricepts PKM. Boeing is planning to machine Boxy 
on its 3-axis Okuma and its 5-axis Northwood Gantry machine that has 
a Fanuc STEP-NC control. CCAT is planning to machine boxy also but 
the machine or machines have not yet been chosen.

NIST is going to demonstrate an application that modifies feeds and 
speed on the control and then uses MTConnect to return the overrides 
to the STEP-NC Explorer  to update the STEP-NC data.

The Bath meeting is now just 4 weeks away so we agreed to increase 
the frequency of the telcons to weekly. Therefore, the next 
conference call will be at the regular times on Wednesday September 2nd.

Martin Hardwick was able to make a Goto meeting recording of the 
conference call.
