A work piece positioning system structured for use with work piece processing equipment. The positioning system comprises a guide rail assembly having at least one guide rail, a measurement pattern positioned on at least a portion of at least one guide rail; and a carriage assembly structured for slidable engagement with at least a portion of the guide rail of the guide rail assembly. The carriage assembly may include a controller configured for wireless data communication with at least one mobile computing device, and a stop block. In different embodiments, the controller can be programmed to receive data communicated from an electronic measurement device; to receive a cut-list including a list of cuts to be made on the work piece processing equipment; and/or to receive data derived from at least one information source associated with at least one dimension of a work piece or at least one attribute of a work piece environment.

The flip stop has a body, a fixing component, and a flip arm. The body has a nut side, a track side opposite to the nut side, and an abutting portion disposed near the track side and tapering toward the track side. The fixing component has a bolt and a nut. The bolt is located through the body and has a bolt head located near the track side and allowing the flip stop to move along a T-track. The nut is threaded with the bolt to locate the body between the nut and the bolt head and is located near the nut side of the body. The flip arm is pivotally connected to the body. When the body and a T-track are fixed with respect to each other, the body is in line contact with the T-track, which leads to more stable and accurate positioning.

An adjustable flip stop has a body, a fixing component, and a flip arm. The fixing component has a bolt and a nut. The bolt is mounted through a fixing hole of the body and has a bolt head contained in an interior of a T-track, and the nut is threaded with the bolt to locate the body between the bolt head and the nut. The flip arm has a connecting element, an arm body, and an adjusting element. The connecting element is pivotally connected to the body, and the arm body has a longitudinal direction. The adjusting element is combined with the connecting element and is capable of being combined at different positions of the arm body in the longitudinal direction to make the arm body and the connecting element fixed with respect to each other. The adjustable flip stop is applicable with fences of different heights.

A clamp for a tool holder is disclosed. The clamping tool holder includes a body having an insert-receiving pocket and a threaded clamp-receiving bore with a coolant opening for receiving pressurized coolant from a coolant source. A clamp includes a threaded aperture extending from a top surface to a bottom surface and coolant passages in fluid communication with a coolant header. A clamp screw is threaded into the threaded aperture of the clamp. The clamp screw includes a plurality of coolant passages in fluid communication with the coolant opening of the body, and at least one coolant channel in fluid communication with the coolant passage. Coolant from the coolant source enters the coolant opening of the body, travels into the clamp screw, travels into each coolant passage of the clamp, and then exits the clamp in a direction toward a cutting insert-workpiece interface.

An adjustable device for cutting an object has a frame with a back member that extends between a pair of feet. The feet are adjustably connected to a work bench or portable work table assembly. A spring biasing member has a back plate and a pair of side rods that extend from the back plate, through the back member, and are connected to a front member. A plurality of spacers are positioned between the front and back members.

A fence assembly of a table saw includes rear and front sliding members slidably disposed on two rails of a table respectively, the rear sliding member having three equally spaced top projections, the front sliding member having three equally spaced forward projections, a transverse member interconnecting the sliding members, and a spring biased workpiece guide bar on the transverse member. The workpiece guide bar includes a front locking element for locking the workpiece guide bar on the front sliding member, a rear locking element for locking the workpiece guide bar on the rear sliding member, the rear positioning element having a recess for receipt of the top projection, and a spring biased lever pivotably secured to the workpiece guide bar. A latch of the lever can be engaged with a protuberance of the front locking element to lock the workpiece guide bar or disengaged from the protuberance to unlock same.
