Embodiments of this disclosure provide a system and method for cutting composite materials. The system includes a material supporting surface, an oscillating saw suspended from a rotatable head on an arm, a two-axis gimbal coupled to the rotatable head for adjusting a cutting angle of the oscillating saw, and a material clamp for clasping the composite material to prevent the composite material from slipping while being cut with the oscillating saw. An automated embodiment of the system further includes a controller for instructing the oscillating saw to cut the composite material by guiding the saw via coordinated movement of the rotatable head, the arm, and the gimbal. A method of cutting a woven composite material includes feeding the material on a support surface, providing an oscillating saw blade on a guiding mechanism, and cutting the material by moving the saw blade in a direction based on the guiding mechanism.

A structure body cutting system includes a cutter system mounted on a cutting side trailer and configured to cut a blade to be cut, and a feeder system mounted on a feeding side trailer and configured to send out the blade to the cutter system. The blade is placed so as to straddle between the cutter system and the feeder system. The feeder system sends out the blade to the cutter system as the feeding side trailer comes close to the cutting side trailer. The cutter system cuts the blade into a plurality of cut segments by cutting the blade sent out from the feeder system.

A hand saw machine with environment control device includes a motor assembly, a cutting tool for cutting a work piece and driven to rotate by the motor assembly, and an environment control device connected to the motor assembly, wherein the environment control device includes an air intake hood sheltering the motor assembly from residual particles ejected by the work piece during cutting, wherein the hand saw machine further has an air passage formed by the environment control device and the motor assembly.

The present disclosure is directed to a reciprocating saw assembly including a saw unit. The saw unit includes a reciprocating mechanism having a reciprocating spindle to which a saw blade is attachable, a drive unit for providing torque to the reciprocating mechanism, causing the spindle to reciprocate, and an outer housing in which the drive is received. The outer housing includes a handle portion graspable by a user during a cutting operation. The reciprocating saw assembly further includes a clamping unit having a clamp housing pivotably coupled to the outer housing and a jaw movable relative to the clamp housing between a clamping position, in which the clamping unit is affixed to a workpiece to be cut, and a release position, in which the clamping unit is removable from the workpiece.
