摘要： According to one implementation, a machining apparatus includes an electromotive saw and an attaching structure. The electromotive saw cuts off a workpiece to be machined. The attaching structure attaches the saw to an arm of a robot. Further, according to one implementation, a machining method is provided. In the machining method, a machined product is manufactured by processing a composite material or a honeycomb structure with a cutting tool attached to an arm of a robot. Further, according to one implementation, a machining method is provided. In the machining method, a machined product is manufactured by processing a workpiece to be machined with a cutting tool attached to an arm of a robot. The workpiece is processed along a shape of a jig for setting the workpiece. The workpiece is processed with contacting a guide with the jig. The guide is attached to the arm.

摘要： According to one implementation, a feeding device of a hole inspection device having a probe includes an attaching jig, a movement mechanism, and a positioning jig. The probe is inserted into a hole to be inspected of an object in a central axis direction of the hole, for inspecting the hole. The attaching jig attaches the hole inspection device to the feeding device. The movement mechanism linearly reciprocates the hole inspection device together with the attaching jig. The positioning jig positions the movement mechanism to the object. A moving direction of the attaching jig and the hole inspection device is made parallel to the central axis direction of the hole by positioning the movement mechanism.

摘要： According to one implementation, a drill includes the first cutting edges, the second cutting edges and a deflection reducer. The first cutting edges drill a prepared hole to a workpiece. The first cutting edges are formed in a tip side of the drill. The first point angle and each first relief angle of the first cutting edges continuously or intermittently decrease from the tip side toward a rear end side of the drill. The second cutting edges finish the prepared hole. The second cutting edges are formed at positions away in the rear end side from the first cutting edges. The second cutting edges have the second relief angles at a maximum diameter position. The deflection reducer reduces deflection of the second cutting edges. The deflection reducer is formed between the first cutting edges and the second cutting edges. The deflection reducer is inserted into the prepared hole.

摘要： According to one implementation, a rotary cutting tool includes: a body without a back taper; and a cutting edge part integrated with the body. The body has a flow path of a cutting oil inside the body. The cutting edge part has a first supply port that supplies the cutting oil toward a workpiece. The body has at least one second supply port that supplies the cutting oil to a clearance formed between a bush for positioning and the body. The bush is used by being inserted in the body.

摘要： According to one implementation, a positioning device positions a hole inspection device to a hole formed in an object. The positioning device includes a guide unit and a detachable member. The guide unit has a positioning hole and a flat supporting face. A cylindrical or columnar positioning member is slidably inserted into the positioning hole. At least a tip of the positioning member is inserted into the hole. A central axis of the positioning hole and a reference line of the hole inspection device for measuring or inspecting the feature of the hole lie on a same straight line. The guide unit is set by contacting the flat supporting face to a surface of the object surrounding the hole or a flat surface of a jig placed on the object. The detachable member attaches a part or all of the guide unit to the hole inspection device.

摘要： According to one implementation, a tool feeding mechanism for a handheld tool rotating device, having a holder and a first air motor, includes a coupler, a fixing member, a moving mechanism and a second air motor. The holder chucks and holds a rotating tool. The first air motor rotates the holder. The tool feeding mechanism is attached to the tool rotating device. The coupler is attached to the tool rotating device. The fixing member is attached directly or indirectly to a workpiece of hole processing using the rotating tool. The moving mechanism moves the coupler relatively to the fixing member in a tool axis direction. The second air motor powers the moving mechanism.

摘要： According to one implementation, a drill includes: a body without a back taper and a cutting edge part. The body has a flow path of a cutting oil. The flow path is branched to first and second flow paths inside the body. The cutting edge part has a first supply port that supplies the cutting oil toward a workpiece. The first supply port is an outlet of the first flow path. The body has a second supply port that supplies the cutting oil to a clearance between the body and a bush for positioning the body. The second supply port is an outlet of the second flow path. The second flow path has a pressure loss by which the cutting oil is not scattered from the second supply port in a radial direction of the body but exuded from the second supply port.
