An example pipe cutting tool includes a plurality of actuators and a plurality of cutters. Each of the plurality of cutters is connected to at least one separate actuator of the plurality of actuators. The at least one separate actuator is configured to move the cutter between a pre-deployed and deployed position. The deployed position is beyond the pre-deployed position. The plurality of cutters may include a first and second cutter, with the at least one separate actuator connected to the second cutter moving based, at least in part, on one or more cutting conditions. An example method of cutting a pipe includes extending a first cutter to contact the pipe, cutting at least a portion of the pipe using the first cutter, detecting a cutting condition, extending a second cutter based, at least in part, on the cutting condition, and resuming the cutting using the second cutter.

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 cutting length display device for a hand-held machine tool includes at least one display unit that has at least one light source. The display unit is configured to display at least one position of a cutting edge of a machine tool on a workpiece to be machined depending on a set cutting depth of the machine tool by way of a light beam. The display unit has a mirror unit that is configured to deflect the light beam depending on the set cutting depth of the machining tool.

A band saw machine includes a working platform, a cutting machine, a vertical displacement element causing the cutting machine to move vertically, a height sensor and a central processor. The working platform includes a reference plane for placing a workpiece. The cutting machine includes a driving wheel, a driven wheel, a band saw wound on the driving wheel and the driven wheel, and a motor that electrically drives the driving wheel. The band saw includes a starting cutting tooth and a processing cutting tooth sequentially arranged. The height sensor detects a starting cutting point of the workpiece farthest from the reference plane. The central processor receives information of a position of the starting cutting point, and controls a displacement speed of the vertical displacement element and a first rotational speed of the motor to cause the starting cutting tooth to first cut at the starting cutting point.

The present disclosure relates to a chainsaw 1 comprising a housing 3, a guide bar 5, projecting from the housing 3, and one or more handles 9. The guide bar 5 has a main direction of extension 15 defined by its center-line. The housing comprises an outer shell 3 made of plastic, which has at least a first 23 outer groove filled with a contrasting plastic material, wherein the groove at least partly extends straight in a transverse direction 17 that deviates less than 3 degrees from a direction perpendicular to the main direction 15 of extension of the guide bar 5. This provides an indication that facilitates precise and safe felling of trees.

The invention relates to a method of remote control of a portable automated panel cutter comprising a power cutter, the method comprises the steps of: establishing a wireless communication channel between the portable user device and the controller. Via the portable user device, select one of a plurality of predetermined cutting offs, each of which is definable by at least one predetermined measures type. For the selected cutting offs establishing a required number of measures corresponding to the at least one measures type. Via the portable user device, provide selected to the controller the established measures for the selected cutting off, and via the portable user device, initiating cutting operation of the panel cutter according to the selected cutting off and the established measures.

The invention relates to a method of remote control of a portable automated cutter comprising a power cutter. The position of the power cutter is controlled by a controller based at least partly on input provided by a user via an intelligent measuring tape. The intelligent measuring tape comprising a distance sensor, an orientation sensor, a micro-controller and a user interface comprising a communication element. The user is extracting tape from the intelligent measuring tape enclosure along at least one part of a representation of a cutting off, the distance sensor establishing a linear measure of the length of the extracted tape, by activating the communication element, the user facilitates wireless communication of the established linear measure from the micro-controller to the controller, and upon receiving the linear measure, the controller controls the power cutter according to the established linear measure.
