For better stability, work with the propel motors to the rear of the machine. Dump spoil piles as far away from the excavation as possible to avoid caveins. When doing excavation jobs on slopes, level the machine by digging a shelf (or bench cut).

Automation of the pressure probe operation, particularly automatic tracking of the meniscus location in the glass microcapillary tip, would address many of the abovementioned issues, and to date, several attempts have been made to monitor the meniscus location using electrical resistance (Hüsken et al., 1978) or hardwarebased image analysis (Cosgrove and Durachko, 1986; Murphy and Smith, 1998).

· TAYLOR''S STABILITY NUMBER If the slope angle, height of embankment H, the effective unit weight of material, angle of internal friction '', and unit cohesion c'' are known, the factor of safety may be determined. Taylor (1937) conceived the idea of analyzing the stability of a large number of slopes through a wide range of slope angles and angles of internal friction, and then representing the

working operation on the part without stress relieving. Parts that are finished by grinding frequently have a thin surface layer with high residual stress in tension. Such residual stress combined with the tensile stress from loading, may give a resultant stress sufficiently great to cause a fatigue crack to start.
