An abrasive article having a plurality of apertures arranged in a non-uniform distribution pattern, wherein the pattern is spiral or phyllotactic, and in particular those patterns described by the Vogel equation. Also, provided is a back-up pad having a spiral or phyllotactic patterns of air flow paths, such as in the form of open channels. The back-up pad can be specifically adapted to correspond with an abrasive article having a non-uniform distribution pattern. Alternatively, the back-up pad can be used in conjunction with conventional perforated coated abrasives. The abrasive articles having a non-uniform distribution pattern of apertures and the back-up pads can be used together as an abrasive system.

In order to respond flexibly to various processing modes, such as forming curved surface shapes, when cutting a workpiece using a wire saw, this wire saw device (1) is provided with: a single robot arm (2) that is capable of moving freely by means of multi-axis control; a wire saw unit (3) that is detachably connected to the robot arm (2) via a tool changer (7); a wire (8) that spans a plurality of pulleys supported within the wire saw unit (3); and a workpiece cutting zone (20) that is established between the pulleys. The workpiece is cut to a prescribed shape by moving the robot arm (2) in a preset direction while running the wire (8) of the wire saw unit (3) and pressing the wire (8) against the supported workpiece.
