Quality control & assurance at TATC

 

TATC has a well equipped Metrology Laboratory with a staff of Quality Control Engineers and Technicians.

The Laboratory provides its services to both internal (departments) customers and external customers, the latter at a nominal fee according to the volume of business.

 It is equipped as below according to the field of use:-

1. Dimension Verification

The TATC Metrology Laboratory is equipped with two Coordinate Measuring Machines (CMMs) i.e. (One Computer Numerically Controlled (CNC), i.e. automatic and another one manually controlled).

These High Precision CMMs are capable of measuring three dimensional geometries (in the X, Y and Z axis). The measurement software used is the Mitutoyo COSMOS CMM software on both machines. COSMOS stands for Controlled Open Modular Operation Support, and it controls part and sub-program management and file organization of the operation procedures.

Capability

The CNC CMM can handle work pieces and components up to 1100mm in the X-axis, 658mm in the Y-axis and 600mm in the Z-axis. The Manual CMM can handle work pieces with dimensions; X=500mm Y=400mm and Z = 300mm.

The COSMOS Program can also be used for scanning and plotting profiles of components thus eliminating the sketching and drawing activity of complex profiles.

2.  Profile Verification

The laboratory has a Profile projection capable with a protractor screen of 356mm. Used to project a workpiece surface or contour on screen for dimensional measurements or observation

Tool makers microscope for micro-measurements with a vertical working distance of 150mm, a working length of 72mm and a magnification accurancy of 0.1%.

Roundness testing machine capable of evaluating roundness, peak height, valley depth, flatness, mean roundness squareness, coaxility, concentricity and parallelism, at a max O/D and I/D of 280mm and a table surface diameter of 165mm. Maximum workpiece load is 25kg.

Surface finish measuring machine capable of handling up to 62 measurement parameters (26 roughness parameter and 36 waviness parameters). The built- in plotter is capable of plotting various profiles, roughness and waviness profiles and bearing area curves.

3.  Calibration

TATC Metrology Laboratory has calibrating equipment for industrial measuring hand tools, such as vernier calipers, micrometer screw gauges, dial gauges, bore gauge, etc.

• High grade ceramic gauge blocks (Grade O)

• Precision step gauges for dimensional measurement verification of ranges 0-150, 0-300 and 0.600mm.

•  Dial gauge calibrators for industrial dial gauges of all capacities.

• Electrical Mu-checkers (μ-checkers) for sensitive and high precision dial gauge calibration and verification of sensitive dimensions such as engine block bores, crankshafts and camshafts (bores and shafts).
