摘要： In a wire electric discharge machine that machines a blade section of a cutting tool, in a state in which a rod-shaped reference jig is fixed to a rotary axis, a position on an outer circumferential surface of the reference jig is measured at each rotation position and stored. A rotational run-out error is calculated based on the stored rotational run-out position information, and a machining program is corrected to cancel the rotational run-out error.

摘要： Disclosed herein is a multi-wire saw including a wire, a set of guide rollers, an adjusting unit for adjusting tension of the wire wrapped around the guide rollers, a fixing base for fixing a workpiece to be cut by the wire wrapped around the guide rollers, and a moving mechanism for moving the workpiece fixed to the fixing base toward the wire. The adjusting unit includes an adjust roller around which the wire is wrapped, a rotational speed control section for controlling the rotational speed of the adjust roller, and a supply roller around which the wire is wrapped to be supplied to the adjust roller.

摘要： A block in an electric discharge machining program is read out and analyzed, and when determined that a machining route correction command is issued to correct the machining route at a corner formed by consecutive first and second machining blocks, the machining route is corrected such that the end point of the first machining block, an extension point obtained by extending the first machining block from the end point thereof by a predetermined distance in the machining advancing direction, and a new start point obtained by partially removing the second machining block by a predetermined distance from the start point thereof are connected. Then, the wire electrode is moved with respect to the workpiece, following the corrected machining route.

摘要： A discharge pulse number generated between a wire electrode and a workpiece is counted every predetermined time. A ratio Px/Ps of this counted value Px to the reference pulse number Ps will be determined to control an amount of coolant in response to this ratio Px/Ps. Also, in response to this ratio Px/Ps, an amount of movement within predetermined time is controlled. Further, through the ratio Px/Ps and the like, quiescent time to be controlled by the detection voltage generator is controlled. Thereby, surplus supply of energy is prevented, the machining speed and machining precision is improved and any disconnection of the wire electrode is avoided.
