a. Two Axis Co-ordinate Universal Measuring System :
Microrep
Model MIL 201. This is a machine for two co-ordinate measurement of external threads,
internal threads, blind or through holes, taper, profile angles, circles and radii.
The machine
is designed to give an effective support to the verification and calibration of
external Micrometers, Dial Indicators, Micrometer Heads, Depth Micrometers, Depth
Gauges, Bore Gauges, Snap Gauges etc. This helps to achieve the quality requirements
of the components manufactured in order to comply the requirements of ISO-9000.
Machine Capabilities
This includes
different measuring methods both Contact and Non-Contact types, Profile comparison,
the measuring range being X = 200 mm & Y = 100 mm, the working stage with an
area of 800 x 240 mm, max. load up to 40 kg. adjustable centre cradle up to 750
mm, V-type supports adjustable up to 850 mm. The Tilting head has an angular movement
of ± 15° for sharp focusing both with flanks of external threads. The microprocessor
based digital readout system offers a resolution of 0.001 mm permitting a wide range
of linear and circular calculations. PC-based software is coupled to facilitate
gauge management.
b. 3-D Co-ordinate Measuring System
The Dimensional
Metrology Laboratory is equipped with a Brown and Sharpe 3-D CMM Model Microexcel
765. This is an advanced system and can quickly measure / calculate the three dimensional
spatial relationship of the workpiece, performs statistical analysis, reverse engineering,
contouring, layout inspection, tool set-up and has a consistent volumetric accuracy
of 0.001 mm and a repeatability of ± 0.00 4 mm.
