Dimensional verification of NC machining profiles using extended quadtrees

Checking for machinability on surface patches

“…The checking algorithm is similar to the algorithm for NC verification using extended quadtrees [21]. Since the machinability check is performed before the generation of the toolpath, this algorithm will save computational cost in toolpath generation if the part surface is non-machinable.…”

Removal analysis of WEDM’s tapering process and its application to generation of precise conjugate surface

“…The other proposed solid modeling for analysis of four-axis cutting geometry [5]. Some past studies were focused on the CAD design for the WEDM process [5][6][7]. But discussion on the removal mechanism around corners or arcs that directly affects the machining accuracy was still rare.…”

Verification of NC machining processes using swept volumes

“…The sweep-envelope differential equation method is probably the most elegant method to date that has proven to be suitable for NC verification [7,8]. Some of the works that have addressed NC verification but have not used swept volume methods include Voelker and Hunt [9], Menon and Voelcker [10], Oliver and Goodman [11], Narvekar et al [12], Takata et al [13], Jerard and Drysdale [14,15], Koren and Lin [16], Menon and Robinson [17], Oliver [18], Liang et al [19], Liu et al [20], Lee [21], Lo [22], Chiou et al [23,24], Elber and Cohen [25], Balasubramaniam et al [26,27], Rao and Sarma [28], Jensen et al [29], Bohez [30], Mann and Bedi [31], Yoon et al [32], Bedi et al [33], Gray et al [34,35], Fussell et al [36], Lauwers et al [37], Jun et al [38], Bohez et al [39], and Langeron et al [40].…”
