Improvement of Geometric Accuracy in Micro-Slot Punching with Small Pitch

Geometric Effects When Measuring Small Holes With Micro Contact Probes

A coordinate measuring machine with a suitably small probe can be used to measure micro-features such as the diameter and form of small holes (often about 100 μm in diameter). When measuring small holes, the clearance between the probe tip and the part is sometimes nearly as small as other characteristic lengths (such as probe deflection or form errors) associated with the measurement. Under th...

The optimal clearance design of micro - punching die

AbstrAct Purpose: The purpose of this research paper is focused on the optimal clearance design of micro-punching die by abductive network and SA method. Design/methodology/approach: The punching data (input) and wear size (output) were collected for a training database. In order to select proper clearance to evaluate the wear of die, the abductive network was used to establish an efficient rel...

Accuracy Improvement of Tropospheric Delay Interpolation in RTK Networks

The effect of troposphere on the signals emitted from global navigation satellite system (GNSS) satellites, appears as an extra delay in the measurement of the signal traveling from the satellite to receiver. This delay depends on the temperature, pressure, humidity as well as the transmitter and receiver antennas location. In GNSS positioning, tropospheric delay effects on accuracy of differen...
