A machine tool operation monitoring system which detects an abnormal operation of a machine tooland in which when the operation of each machine toolexceeds a normal operating range of each machine tooland/or when a moving state of a constituent portion of the machine tooland a material exceeds a normal range, wherein the machine toolbreaking out an operation abnormality is identified by any one of the following operations: a. monitoring an image obtained by projecting reflected light from a reflecting display plateprovided for each machine toolonto a camera; and b. monitoring a difference in projecting direction of emitted light from a lampprovided for each machine toolonto an optical sensor

Machine tool operation monitoring system

A cutting toolincludes a cutting edge equipped with a helically curved grooveat a side outer periphery in the longitudinal direction, and a coolant passage pipeextended internally and communicatively connected with ejection holesof coolant arranged inside the grooveby way of a coolant passage pipebranched from the coolant passage pipeextended around a rotation center axis along the longitudinal direction or along the helically curved groove.

Laminate molding equipment includes a molding part with a molding table on which a three-dimensional shape molded object is molded, a powder layer forming part supplying material powder on the molding table to form a powder layer, a light beam radiating part radiating a light beam to the powder layer to form a solidified layer, the powder layer forming part includes powder laminating equipment sequentially forming the powder layer on the molding table by moving along a predetermined direction at the molding table, and a moving position detecting unit detecting a moving position along the predetermined direction at the powder laminating equipment, and the control part recognizes the moldable region by output from the moving position detecting unit, and controls the light beam radiating part, and scans the position of the light beam by adjusting angles of two scan mirrors according to processing data of controlling the scanning device.

Laminate molding equipment and laminate molding method

A cutting method in which, in cutting a circumferential face of a work, control is enabled to make a cutting velocity constant accurately by using a cutting tool projecting from a main shaft which turns around a predetermined position serving as a center and for which a turning radius is adjustable, wherein, in the case that a turning angular velocity of the main shaft is represented as &#x3c9;, a distance from a turning center to a tip of the cutting tool is represented as R, and a cutting velocity of the tip of the cutting tool is set to a constant value C, making the cutting velocity of the cutting tool constant by performing control such that &#x3c9;0 changes in association with a change in the distance R so that&#x3c9;=()/is formulated (where {dot over (R)} denotes a time differential of the distance R), thus providing an even cut face.

Cutting method for inner circumferential face or outer circumferential face of work

Three-dimensional molding equipment includes powder supply equipment configured to supply powder material and form a powder layer, and a light beam scanning unit configured to radiate a light beam to the powder layer and move a radiated location thereof, where a three-dimensional shaped molding object is manufactured by alternately repeating processes of forming the powder layer and sintering the powder layer with light beam radiation. A region used for manufacturing the three-dimensional shaped molding object is divided into a plurality of divided regions such that respective divided regions have an equal-length molding path which is to be a scanning route of the beam such as having unequal-length molding parts by a scanning route of the beam, and radiation is executed by a plurality of the light beam scanning units to the respective plurality of divided regions to improve molding efficiency.
