Quality Management in Space Propulsion Manufacturing.

MECHANICAL INSPECTION

Mechanical inspection employs both manual and automated measurement techniques completely integrated within a software environment for detailed documentation. Within this environment, we monitoring every working process, realising constant improvement in product quality. Typical areas of work include:

	CNC-measuring of work pieces with 3-D measuring machines and computer assisted measuring stations. Database recording of measurements.
	Measurement and checking of surface texture for roughness and waviness.
	Calibration of measuring equipment with database recording of results. Cyclical calibration performed on over 3,000 items of manual measurement equipment.
	Force-lift measurement of spring characteristic curves.
	Incoming goods inspection, checking certificates. Transfer of materials to the appropriate specialist laboratories where necessary.
	Supporting development programmes with measuring equipment first-sample measurement, tolerance verification and methods development.
	Monitoring the precision of production machines by special sample component checks.
	Programming of measurement programs. Software evaluation. Programming measurement on the CAD model (CATIA, VDA, IGES)

 

FACILITIES
Mechanical inspection facilities include:

	4 air-cushioned portal measuring machines with a maximum capacity (XYZ axis) of 1,500 x 1,800 x 1,500 mm. Measuring accuracy <4 µm. Machine accuracy and quality constantly controlled by the manufacturer or an internal calibration laboratory; metromec CM 3.3 evaluation software, Silma (off-line programming, CAD models).
	Perthometer S6P (a fixed roughness measuring device). Contacting measurement equipment. Contactless measurements with laser technology.
	Computer-assisted measuring station with infrared scan measuring device for photometric measuring of exterior component part geometries (measuring accuracy < 2µm).
	Form tester MMQ3 true-running measuring device as a computer-assisted measuring station for measuring axial-symmetrical component parts (measuring accuracy approximately 1 µm).
	Approximately 3,000  manual inspection and measurement tools.
