A drill bit for a drill includes at least one flute having a rake face including a flute edge and at least one cutting edge having a profile that extends along at least a portion of a length of the cutting edge, the rake face extending from the cutting edge. A chip breaker formed in the rake face, the chip breaker being a continuous groove located adjacent the cutting edge, the groove having a starting end and an exit end opening into the flute edge, the starting end having a depth that is less than a depth of the exit end of the groove, wherein a shape of the groove at the starting end is different from a shape of the groove at the exit end.

The present disclosure is directed to a handheld power tool with a touch screen. In an embodiment, the interactive power tool comprises a power source, a video display mounted on a surface of a housing, the video display being integrated with a touch sensitive display, one or more sensors attached to the housing, and processing circuitry, within the housing and electrically coupled to the power source, configured to identify a type of an attachment connected to the interactive power tool, switch the video display to display image data associated with the type of the attachment, receive sensor data from the one or more sensors, and update the image data based on the received sensor data from the one or more sensors.

A processing apparatus includes a cutting tool that processes a clamped workpiece, a quenching unit capable of emitting a laser beam, and a vibration cutting unit capable of vibrating a distal end with a vibration cutting tool mounted thereon. The cutting tool, the quenching unit, and the vibration cutting unit are movable relative to the workpiece. The cutting tool cuts the workpiece before being quenched. The quenching unit applies laser quenching as a surface hardening treatment to the workpiece. The vibration cutting unit finishes the quenched workpiece by applying the vibration cutting tool to the workpiece while vibrating the vibration cutting tool.

A laser-transmitting machining tool is disclosed. The laser-transmitting machining tool has a plurality of faces including an entrance face, a rake face, a flank face connected to the rake face, a rake side face extending between the entrance face and the rake face, and a flank side face extending between the entrance face and the flank face. The connection of the rake face to the flank face defines a cutting edge. The rake face extends away from the rake side face to define a rake angle. The entrance face is configured to receive and refract a laser beam to the rake face, the flank face, and the cutting edge for causing the laser beam to refract into and heat the workpiece at a compression region extending proximate at least the rake face and a tensile region extending proximate the flank face. A system for machining a workpiece is disclosed. A method for machining a workpiece is also disclosed.

A drill bit for a drill includes at least one flute having a rake face including a flute edge and at least one cutting edge having a profile that extends along at least a portion of a length of the cutting edge, the rake face extending from the cutting edge. A chip breaker formed in the rake face, the chip breaker being a continuous groove located adjacent the cutting edge, the groove having a starting end and an exit end opening into the flute edge, the starting end having a depth that is less than a depth of the exit end of the groove, wherein a shape of the groove at the starting end is different from a shape of the groove at the exit end.

The present disclosure relates to the technical field of deep hole machining, particularly to a rear-mounted deep hole machining on-line detection and deviating correction device, which provide solution to the difficulty in observing the machining site and correcting the cutter deviation in deep hole machining. The device comprises a cutter bar provided with a plurality of iron blocks mounted uniformly in a circumferential direction, wherein each of the iron blocks is provided with a heating device in the interior thereof and a wear-resistant block mounted on the top thereof, wherein mounted on an end face of the other end of the cutter bar is a pyramid prism, wherein a laser transmitter and a photosensitive sensor are mounted in a height corresponding to the height range of the pyramid prism, wherein the incident beam emitted by the laser transmitter is oriented by a laser orientating block. The advantages of the disclosure lie in that the information of the position the deep hole cutter during deep hole machining process and whether the deep hole is skewed or not can be obtained in time, thereby facilitating a solution to the difficulty in detecting the workpiece deep hole straightness and on-line deviating correction, improving the position accuracy such as straightness of the deep hole and reducing the rejection rate of the workpiece.

A rigid or semi-rigid MAP container includes microperforations at least 0.4 mm in length, with diameters between 20 and 300 microns that are uniform within +/10% through both the laminated rigid/semi-rigid and sealant layers of the container. The microperforations are created using one or more micro-drills rather than a laser. A backing support can be used to inhibit container deformation during drilling. The laminate can include an outer PET layer, and/or an inner sealant layer that includes polyacrylonitrile resin and/or polyester film. Initially, the lid is hermetically sealed to the base by the sealant layers, and is mechanically resealable to the base after initial use. The microperforations can be widely distributed or concentrated in target areas. The base can be divided into compartments that are in gas communication with each other or hermetically isolated with separate configurations of microperforations that are optimal for the expected contents of each compartment.

A laser beam is transmitted through a drill bit comprising diamond or other suitable light-transmitting material having sufficient hardness. The laser beam exits a tip of the drill bit, thereby heating and softening the material being drilled at and/or near the interface of the drill with the material being drilled. The process may be utilized to drill hard and brittle materials such as ceramics and semiconductors, composites and ceramic matrix composites. The process may cause high pressure phase transformation, resulting in a more ductile and plastic material near the drill point/tip. The process provides more rapid drilling, improved surface quality in drilled holes, and less tool wear.
