A coping cut machine can include a workpiece platform having a support surface for receiving a workpiece support surface. The coping cut machine can have a rotary cutting device supporting at least one knife, and at least one workpiece alignment member supported by the workpiece platform for aligning a workpiece supported by the workpiece platform relative to the rotary cutting device. In response to sliding the workpiece along the at least one workpiece alignment member and during rotation of the rotary cutting device, the at least one knife operates to perform a coping cut on an end of the workpiece. The rotary cutting device can optionally be operated bi-directionally to cut either end of a workpiece. The rotary cutting device can comprise a modular rotary cutting assembly having a keyed profile portion received in a keyed profile aperture of a drive wheel, and that is removable from the coping cut machine.

A cold-weld burr removal system is disclosed according to various embodiments. The cold-weld burr removal system can include a clamping block having a clamping passage that extends along an alignment axis, and a removal block having a guide passage alignment axis centered about the alignment axis. The removal block can define a burr receiving chamber. The system also can include a cutting head insert having a cutting portion and a cutting passage. The cutting head insert can removably attach to the removal block and the cutting portion can protrude into the burr receiving chamber. The system can include a linear actuator that connects the clamping block to the removal block. The linear actuator can move the removal block in a direction along the alignment axis to increase a separation distance between the clamping block and the removal block when a linear actuation initiator initiates movement of the linear actuator.
