About COE



Bob Deragisch, Parker Hannifin
(Second year of three year term, 2nd term)

Bob Deragisch started working at Parker Hannifin shortly after attending the University of California at Irvine and Chapman University in Orange, California. During the last 30 years, Bob has held numerous positions throughout the IT and Engineering departments of Parker.

Bob has been supporting Parker’s use of CATIA since he installed version 2 in 1985. Bob was also the original author of numerous engineering applications written specifically for Parker design use, many of which, although hopefully revised and modified since, are still in use today, both within and outside of the CATIA environment.

Currently, Bob is responsible for managing Engineering Services for the Aerospace Group, while also directing eBusiness initiatives for the Group, with an emphasis on collaboration with customers, suppliers, and partners. Included in this direction is deployment of Catia and Enovia Matrix One across the Aerospace Group of Parker Hannifin.

Bob graduated Summa Cum Laude from Chapman University with a Bachelor of Arts in Organizational Leadership, and received his Master of Arts in Organizational Leadership with an emphasis in Organizational Development in January of 2007. He has been married for over 30 years to Debbie, and together they have two “adult children” ages 25 (working in the motion picture and television industry, while becoming a teacher) and 28 (a First Officer for Sky West Airlines). Bob and Debbie currently reside in North Orange County, roughly 8 miles from where Bob was born.

Vice President/President Elect

Mike Clare, Boeing
(First year of three year term, 2nd term)

Mike has 25+ years in the aerospace and defense industry, mostly with The Boeing Company. Currently, he is a systems engineer serving as the senior lead on the Support Technology, Technical Data and Training team within Boeing Research and Technology (BR&T). His duties require conducting research in the areas of global customer support for commercial airlines and the US Government – it is Mike’s job to find or build new technologies that improve fleet maintainability and sustainability for Boeing’s customers. His present assignment is an investigative thrust to exploit using 3D engineering source information within the support environment. In particular, Mike is trying to influence CAD suppliers to offer tools and processes that will support products throughout their lifecycles.

Prior to his work with BR&T, Mike worked as a manufacturing engineer for 14 years in areas such as tool design, NC programming, process planning, process engineering and many years as a CAD/CAM site support lead. Mike has been involved in CAD/DAM since his career started with Grumman Aerospace, initially with 2D CADAM systems, then migrating to 3D using CATIA. He has used DELMIA for 3+ years to support Boeing’s 787 maintainability centers of excellence, as well as ENOVIA LCA. Mike also was the lead/system manager for Boeing when working with Dassault Systemes to develop DMU PI as the low-end viewer of V5 data during the late 90s early 200 (V5R2). These responsibilities required communicating with Dassault product managers on a regular basis to understand the requirements and needs of the user community more completely.

Mike has been an active participant at COE since 1996, giving his first presentation in 1997 entitled, “Elimination of Detail Part Drawings”. Since then, Mike has been a presenter six different times at either COE annual events or COE A&D Workshops. As his COE experience matured, Mike became at PIC chairperson in 2006 when he presented the need for a Service After Sales PIC – he has been growing this community within COE since the PIC was created, as demonstrated by increasing numbers of attendees and people willing to present. For the past year, Mike has participated in event planning as the co-chairperson for the 2010 COE A&D Workshop in Ft. Worth Texas as well as still maintaining his role as SAS Process Chair. Mike has also been a COE ATE presenter and a COE forum monitor. Mike has proven through his actions that COE is truly a year round event.

Mike was instrumental in developing the CATIA Operators of Puget Sound (COPS) Regional User Group and served as a Secretary/Vice President. Due to industry consolidation and other factors, COPS is no longer active.

Because of his extensive research and development work within the CAD environment, Mike is often asked to present at various venues to share his knowledge and experiences across a broad array of topics. Most recently, he presented at the 2010 Dassasult Systemes Customer Conference and the Defense Manufacturing Conference in both 2010 and 2006.
