Haas Laboratory

Haas Laboratory

This laboratory is composed of 5 areas: CNC Laboratory, Engine Test Cell, Systems Engineering Research Laboratory, CAD/CAM Laboratory, and a Student Design Center. The following machining equipment are housed in the CNC Lab: Haas CNC lathe SL-20, Haas CNC mill TM1, HS70 electric discharge machine (EDM), and a Z400 rapid prototyping machine. The machining equipment is used to support student design projects, including senior design, and graduate research projects. Conventional machining equipment in this area includes: horizontal lathe, vertical milling machine, gear hobbing machine, gear/spline shaping machine, vertical cut off saw, horizontal band saw, hydraulic shear, grinders, tube benders, MIG and TIG welders, plasma cutter, and assorted hand tools.

The backside of Haas Lab was reconfigured to create a Student Design Center (SDC) in support of design activities in the freshman and lower division courses. The SDC simulates the actual engineering working environment in industry, where the role of engineers is to conceive, design, implement, and operate systems in a team-based setting. This section of the laboratory contains several manual machines including band saws, a lathe, a mill, drill press and several hand tools. An injection molding machine was also acquired to provide students with such operations. The introductory freshman course ME 101 utilizes this section of the laboratory to design, realize and test their designs.

Engine Dynamometer Test Cell (JD 1624A)

The Engine Dynamometer Test Cell supports elective courses, senior design projects and graduate research projects. Students disassemble/reassemble engines to gain insight into engine design, learn to map engine performance, and to test engine components designed for their senior projects. Graduate students are able to develop and demonstrate automotive engine thesis projects in the cell. Equipment currently available includes an Engine Dynamometer/Data Acquisition System and a Horiba exhaust gas analyzer. Software is available for developing engine maps to better control operating conditions, to improve engine performance, and to reduce emissions. Emissions are measured on the exhaust gas analyzer.

Computer-Aided Design and Manufacturing Laboratory (JD 1624B)

The Computer-Aided Design and Manufacturing (CAD/CAM) Laboratory supports design projects, including the Formula SAE senior design project, in the Haas Laboratory. There are 20 PC workstations along with support for printing and plotting. Solid modeling, rigid body motion and finite element analysis is accommodated by the SolidWorks software suite. CAM is accomplished by Espirit software. Other applications in this lab are Pads and RicardoWave. A reference library for design purposes is also available in this laboratory. This lab also supports graduate research projects in advanced applications of CAD/CAM.

Systems Engineering Research Laboratory (JD 1624C)

The Systems Engineering Research Laboratory was recently established and has 10 PC workstations with specialized software as well as software for numerical analysis and data reduction. The specialized software include: Multi-aircraft Control System (MACS) a NASA Ames research tool developed to support human-in-the-loop air traffic simulations; Cockpit Display of Traffic Information (CDTI) a NASA Ames research tool designed to present 3-D surveillance information of the traffic in the vicinity to the flight crew; and Fast-time Simulators an in-house simulator that can be programmed to simulate any aircraft as long as its aerodynamic model is available.
