Client win for Delmia: Dassault Systemes, the French manufacturing technology company with its United States base in Auburn Hills, said Wednesday that automation system design specialist Autotool Inc. of Dublin, Ohio is using the Delmia V5 Robotics system for programming and simulation of its robotic auto assembly cells and lines. By simulating robot motions during design, Autotool can verify that the robots will be able to achieve all the required motions and that there will be no interferences. This means that when a system gets to the build phase, a huge amount of retool time is eliminated -- resulting in up to 30 percent cost savings in tool design and a 40 percent reductions in the number of machines, tools and work centers, according to a 2003 CIMData study on digital manufacturing. "We have used the software on a project where, without Delmia V5 Robotics simulation, it would have been impossible to figure out how to have the robots interface with the various fixtures," said Autotool design engineer Steve Forrest. "The two robots were in a fixed position. Simulation allowed us to optimize placement of the six different fixtures so that the robots could reach all positions and avoid any interferences." Delmia V5 Robotics allows tooling definition, workcell layout, robot programming and workcell simulation. More at http://www.blogger.com/www.autotoolinc.com or http://www.blogger.com/www.delmia.com.

Sustainable Manufacturing Group
Incremental sheet forming machine (research rig) | | Incremental Sheet FormingIncremental Sheet Forming (ISF) is a flexible process for forming sheet metal under the action of a mobile indenter such that almost any 3D shell shape can be made without specialised tooling. The process is recognised as a sustainable technology because it has the potential to enable a move towards small-scale localised production of customised sheet metal parts, as well as re-engineering of damaged or obsolete products. AimsTo understand the process mechanics and expand the process capabilities in order to develop a flexible manufacturing system that is capable of achieving the specifications of typical sheet metal applications. To achieve this goal, the project seeks to:
The technologyAn ISF machine was commissioned at the IfM in October 2004. The machine was designed and built in-house and is the first dedicated rig built outside Japan. Unique features include a built-in force measurement system, rigid and accurate support of the indenter in three directions and space under the workpiece for the future addition of a second indenter. The path of the indenter is numerically controlled via a PCI board motion controller. ApplicationsPotential applications include:
Current researchResearch projects currently underway include:

I have a textbook/workbook “Body Drafting/Detailing” by John Kwiecinski. I used this in a course called Body Detailing offered at Macomb Community college.
Chapter 4 mentions the Body Coordinate System, a grid system of 100 MM spacing. This allows vehicles to be manually drawn in traditional orthographic views.

Stamping Training
Course Title: Sheet Metal Stamping
10 Professional Development Hours/1.0 CEUs
Course Description: The Sheet Metal Stamping Course begins by discussing the evolution of the stamping die, and the impact it has had on the industrial revolution. A review of single operation dies such as blank, compound and pierce, form, and draw dies are also discussed. The dies that perform multiple operations on the same piece, such as progressive and transfer dies are also mentioned. Other topics that are elaborated upon include, different dies relative to the final product’s parameters, complexity of the final product, material that will be used to fabricate from, and production volume requirements of the final product.

2 dimensional strain data
Stamping out die defects
NIST post doctoral research fellow Mark Iadicola examines a sample of sheetmetal tested with NIST's new formability-testing station.
RESEARCHERS AT THE NATIONAL Institute of Standards and Technology (NIST) want to eliminate defects in dies used to make sheetmetal parts. Their work could yield impressive cost savings — particularly for the automotive industry, which spends an estimated $700 million a year on designing, testing, and correcting new dies for its latest models. About half of the total cost goes for remedying unanticipated errors manifested as wrinkles, splits, excessive thinning, or other defects.
Using NIST's one-of-a-kind test equipment, which fits together a metal-stamping test station with an X-ray stress-measurement system, researchers make detailed maps of stresses and strains as sheets of steel and other metals are punched, stretched, or otherwise shaped to achieve the desired part geometry. According to project leader Tim Foecke, the system measures stress and strain behavior in many different directions while the sheet is stretched in two directions simultaneously, a condition most commonly seen in forming operations.
Current methods extrapolate from strain-measurement testing that stretches sheets in only one direction. As a consequence, newly designed dies often undergo successive rounds of refinement to correct for these simplifications in computer models.
U.S. automakers and producers of steel, aluminum, and other metals, including developmental ones, are supplying Foecke's team with samples for testing and evaluation. The aim of the project is to build a database of material properties that designers can feed into computer models for predicting whether would-be dies can form particular metals into specified shapes, within tolerances. Project findings might point the way to new metalforming methods, according to NIST.
