Abstract:
A tool selection method, for a machine tool, comprising the steps of identifying the maximum tip distance (D2) of a currently selected tool (141), a next designated tool (142) and an intermediate tool (143) disposed therebetween; moving a tool rest (10) in the +(plus)X-axis direction after a machining by the currently selected tool (141) is completed until the tip of the currently selected tool (141) is spaced from a workpiece (W) along the X-axis by a distance provided by adding a clearance distance (E) to a difference between the maximum tip distance (D2) and the tip distance (D3) of the currently selected tool (141); moving the tool rest (10) in the +(plus)Y-axis direction until the tip of the next designated tool (142) is aligned with the rotation center axis (12a) of the workpiece (W) in the X-axis direction; and moving the tool rest (10) in the −(minus)X-axis direction.
Abstract:
A method of optimizing the tool selecting operation of a turret according to the contents of a machining program in a turret tool rest allowing a rotating tool to be fitted thereto, including a step (101) for determining whether the rotating tool is contained in various types of tools fitted to the turret, a step (102) for, when the rotating tool is contained, selecting whether the phase of the rotating motion of the rotating tool fitted to the turret is adjusted to be identical in each time the rotating tool is disposed at an indexing position, a step (103) for, when the phase of the rotating motion of the rotating tool is adjusted to be identical, performing a “less than one rotation control” in which the cumulative sum of the turning indexing motion of the turret in a same turning direction is less than one rotation, and a step (104) for, when the rotating tool is not contained in the fitted tools or the adjustment of the phase of the rotating motion is not performed even if the rotating tool is contained in the fitted tools, performing a “shortcut rotating control” in which the turning indexing motion of the turret is equal to or less than half a rotation in any turning direction.
Abstract:
A program unauthorized-use preventing device (10) includes a storage section (12) for storing various optional operation programs in a machine tool, a display section (16) for displaying first and second program-selection images (14, 22) for selecting a desired operation program, and a processing section (20) for reading out the operation program selected on the first program-selection image from the storage section so as to be in a usable state when a device inherent password (18) is input and reading out the operation program selected on the second program-selection image from the storage section so as to be in a usable state when a machine-tool inherent password (24) is input.

Abstract:
To provide a power consumption output device capable of precisely calculating the electricity cost per product manufactured by an apparatus whose power consumption differs in each cycle of operation for manufacturing a product.The power consumption output device for an apparatus that manufactures a plurality of products from a supplied material includes: power detection means (102) capable of detecting power consumption in a target period, including at least a period needed for manufacturing all products that can be manufactured from a single material from the beginning of supplying the material to the end of ejecting a remaining material; and output means (104) for outputting power consumption per product by using the power consumption detected by the power detecting means (102) and the number of products manufactured from the single material.
Abstract:
At the time of two-dimensionally moving a mobile body of a machine tool, to a predetermined position, a speed of the mobile body is gently increased/decreased at an acceleration/deceleration equal to or less than the maximum acceleration/deceleration, from the time when the mobile body reaches a direction change point. Therefore, the moving time is shortened and a rapid acceleration/deceleration may be avoided.
