Description of Requirement Crane Army Ammunition Activity (CAAA) Coordinate Measuring Machine (CMM) Modernization Project

1. GENERAL SYSTEM DESCRIPTION

Crane Army Ammunition Activity (CAAA), Crane, IN, is looking to modernize its inspection equipment by replacing its old Coordinate Measuring Machines (CMMs). Due to increasingly complex parts, quality requirements, and increased production throughput, as well the loss of tribal knowledge of outdated programs and equipment CAAA has recognized a need to replace old equipment that is critical to meet current quality goals. These new CMMs would also allow CAAA to measure with higher accuracy providing customers with higher confidence in CAAA measuring capabilities.

CAAA is in an immediate need of two (2) bridge style, CMMs with updated tactile measuring capabilities. The CMMs shall be run on air bearings and shall have ability to contact scan (passively or actively) the form of features and parts as well as perform single and multi-point measurements with a scanning error of less than .00012”, single point error of less than .000079” and repeatability of at least .000079”. Probe shall also be able to articulate with a front-to-back and lateral tilt range of ±180° with a minimum rotation increment of 2.5° with automatic angular correction for all probing points. CMMs shall come with an automatic probe changer for running fully automated programs that require different probe length/sizes. CMMs shall be able to travel up to 15 inches per second and scan at 5 inches per second to help accommodate timely part throughput. CMMs shall have a measuring range of at least 35 inches in the X- axis, 47 inches in the Y-axis, and 23 inches in the Z-axis. CMM shall come ready to install and include any filters and dryers needed for air lines and have the power requirements of 100-240V (50-60Hz). Must have a rotary table.

CMM control software shall be graphically based and not require coding skills or manually entered drive points to create and run a measurement programs. Control software must run on an included computer system including computer, monitor, mouse, keyboard, printer, and can connect with a hardwired network system for storage backup and program recall. Software shall be able to program, calculate, and output all geometric dimensioning and tolerancing (GD&T) functions and relationships required to determine is a part is acceptable based on blueprints and technical data packages. Software must be able to be programed with or without a CAD model availability. If CAD model is available, software must be able to create and run a program with minimal operator input. Created programs shall be able to be run automatically and be able to create customized physical (printed) and digital reports on intended and found measurements, as well as report pass/fail conditions. Software shall be able to identify quickest possible travel path and probing sequence to optimize program for time and efficiency. Multiple programs shall be able to be loaded at once, so multiple parts can be checked at same time. Training for software shall be included in total price of the machine for up to six operators. CMM Program and Hardware shall come with a minimum of 1 year remote service support.

CMMs shall have modular capacities for use with future additions to the machine to allow for future modernization. CMM shall have ability to easily switch out measuring devices or probes to support active scanning functions, profilometer functions, and 3D non touch optical scanning with either white light functionality and/or triangulation laser technology.

A single CMM cannot exceed the following footprint: length 87.5 inches, width 62.5 inches, and height of 105 inches. CMMs must be able to fit through an entrance that is 6 feet wide by 7 feet tall.

All the above components shall be of brand name or equivalent from the same manufacturer to guarantee interoperability without modification.
