GD&T for Reverse Engineering

Wagstaff Engineering company is an aluminum based company in the Spokane Area. They have requested the help of Idaho Engineering students to aide in their advancement of knowledge on hydro power damns and equipment in order to be better informed for inspections and when making parts for clients.

Background
The current aim of this project is to 3D model a Francis style turbine system from outdated engineering drawings and if possible update them to create better understanding. This will also assist in the understanding of the students and Wagstaff on how they work and what is crucial to operation.

Deliverables
3D model a Francis Turbine on solidworks as well as use add ons such as geomagic to assist in creation. Also an end goal is to create a table top scale model of a turbine with working wicket gates using compressed air instead of water.

Stack Soft
This software allows for the user to look at tolerances and determine which dimensions attribute the most to error. This allows for decisions to be made in order to reduce costs when machining parts.

Geomagic
Geomagic is a software add on that allows for parts that have been scanned using a laser or light scanner and place them into Solidworks to create a solid model out of them.

Coordinate Measuring Machine (CMM)
A tool used at the University of Idaho to obtain accurate measurements from various parts.

Laser Scanner
A tool that the team was trained on to use in order to take objects and scan them so that they can be placed into modeling programs such as Solidworks.

Components
This is a photo of the wicket gates at the Little Falls Dam which were replaced due to erosion. The wicket gates open and close to alter flow of water to turbine in order to meet power demands of the current season

This is a photo of a Francis Turbine which is placed horizontally. Grad student Alex who stands roughly 6'2" is standing in front of the part of the turbine where the outside of the wicket gate assembly can be seen. The outer section is the volute of the turbine which channels water into the outside of the turbine.

Little Falls
The team took a trip up to the Little Falls Dam which is near Spokane in order to get an in person look of a working Francis Turbine and look at key components such as the Wicket Gates.
