Requirements Document

For 704th Test Group/846th Test Squadron

18 November 2019

1.0 PURPOSE

The 704th Test Group (704 TG) mission is to be the premier provider of unique test and evaluation capabilities relevant to tomorrow’s warfighter through world-class people improving technical excellence, cost-effectiveness, and agility. The 846th Test Squadron (846 TS) is assigned to the 704 TG. The 846 TS operates the Holloman High Speed Test Track, a critical testing facility in the development of new weapon and safety systems for the Department of Defense. The 846 TS requires the purchase of one wire electronic discharge machine (EDM) for fabrication of rocket sled parts and components, test articles and test track infrastructure.

2.0 SCOPE

The vendor shall deliver one large capacity wire EDM that meets the following requirements:

2.1 Physical requirements

2.1.1 Workpiece dimensions 49 x 39 x 30 inches or larger

2.1.2 Maximum floor space dimension of 157 x 175 inches

2.1.3 Minimum machining range submerged 31 x 23 x 20 inches with optional riser to allow 30 inches in Z axis. The riser shall be adjustable and capable of being installed and uninstalled by the end user, as needed.

2.1.4 Minimum Z axis cutting range of .05-30 inches

2.1.5 High resolution linear glass scales reading in inches

2.1.6 Wire diameter range of .008-.012 inches minimum

2.1.7 Use Linear Shaft Motors or direct drive ball screws in the axis drive system (no belts in the drive system)

2.1.8 Incorporate a “moving column design” for the Y-Axis component

2.1.9 Submerged machining up to 20.0 inch or greater. Have a stainless steel work tank with a self-cleaning stainless steel seal plate and seal plate movement transfer mechanism

2.1.10 Wire chopper

2.2 Operational requirements

2.2.1 PC based CNC Controllor with LCD touch panel display, keyboard and mouse. Utilizing a

Windows-based embedded operating system that includes all requirements necessary for machining operations, CAD/CAM programming and program storage.

2.2.2 Multiple program input methods to include, keyboard, USB port, and Ethernet

2.2.3 Embedded 3D / 2D CAM programming to provide a step-by-step approach to inputting 3D model data (Parasolid format), extracting the tool path and converting it to an NC program. DXF and IGES CAD files can also be imported directly for conversion to NC programs

Vendor shall specify if there is an annual license fee

2.2.4 Large wire spool capable, 35 lbs. minimum size

2.2.5 Automatically adjusts power settings to compensate when cutting materials with impurities or materials with high amounts of inherent stress, minimizing any repeated wire breakage problems
