About this file
This statement of work outlines requirements for the procurement of a tube bending machine, associated software, and tooling by the National Aeronautics and Space Administration Shared Services Center. The tube bender must be capable of bending titanium and stainless steel tubing up to 0.5 inches in diameter and 0.035 inches thick, with a repeatability of 0.002 inches for length, 0.1 degrees for rotation, and 0.1 degrees for angle. It must have a maximum bend arm rotation of 190 degrees and operate on 120V or 240V power. The vendor must provide software that can import 3D STEP files, create bend tables, compensate for springback, and perform multiple bends or bends beyond the pressure die length. Eight bending die tool sizes are also required, ranging from 0.125 to 0.5 inches in tube diameter and 0.375 to 2 inches in bend radius.
The solicitation number listed seeks the tube bending machine, software, and tooling outlined in the attached statement of work to meet the needs of the National Aeronautics and Space Administration Shared Services Center.

INTRODUCTION
1.1 GENERAL INFORMATION
The Goddard Space Flight Center (GSFC) builds propulsion and other fluid systems in support of spacecraft. Tube bending machines are necessary to bend stainless steel, titanium, and other tubes for the manifolds that are a part of these fluid systems.
1.2 SCOPE
This document gives requirements for the procurement of a tube bender, associated software, and tooling.
1.3 APPLICABLE DOCUMENTS
N/A
2 STATEMENT OF WORK
2.1 TUBE BENDER
The vendor shall supply a tube bender with the following capabilities.
Capable of bending Titanium and Stainless-Steel tubing with a maximum diameter of 0.5” and wall thickness of 0.035”
Low pressure alarm
Machine repeatability: Length +/-0.002”, Rotation +/- 0.1 degrees, Angle +/- 0.1 degrees
Bend arm rotation: Maximum 190 degrees
Input Power: 120V or 240V (not necessary to provide both)
Autonomously rotate tube to perform bends in different planes
The vendor shall provide with the tube bender software that has the following capabilities:
Ability to show a 3D view of tube to be bent
Ability to convert ISO 10303 standard 3D STEP files into a format the tube bender software can use to create tube bending tables
Ability to create bend tables from imported 3D STEP file
Ability to compensate for springback
Ability to operate the machine to overcome a pressure die that is too short
Ability to operate the machine to perform more than one bend inside the pressure die
The vendor shall provide any needed support to install the software onto a customer supplied computer at the customer’s facility if software is not already installed on the tube bending machine. The customer will provide the computer and technicians to do the software install, if needed.
2.2 TOOLING
The vendor shall supply the bending die tooling in Table 1. The tooling shall be compatible with the tube bender supplied as part of this SOW.
Table 1. Tooling Sizes.
