To more effectively utilize data related to machining by a machine tool. An integrated machining system includes: a database that stores, as hierarchized structured data, production data related to steps from design until machining, including data of machining commands to be executed by a machine tool, and data of machining history corresponding to the data of machining commands; and a production data management device that includes a provided information generation unit that generates provided information to be provided externally, by way of acquiring at least either of the data of machining commands and the data of machining history from the database, and referencing a hierarchized structure to acquire elements of data related to specific information.

A tool path curve generation method for generating a curve from a tool path designated by a command point sequence includes: a step of defining a region based on a polygonal line path connecting the command point sequence; a step of determining whether the curve is included in the region on the basis of the geometric shape of the surface of the region; and a step of generating a curve that has been determined to be included in the region in the determination step.

A machining curve creating apparatus create curve of a tool used to machine a workpiece by repeating a procedure of taking, as a partial point sequence, a part of a point sequence expressing the tool path and generating a partial curve. The machining curve creating apparatus includes stored-information-utilized curve generating unit for generating a partial curve utilizing segmented curve information. When curve information utilization determining unit determines to utilize the stored information, the stored-information-utilized curve generating unit generates a partial curve.

A machining time predicting apparatus of a numerically controlled machine tool divides a tool path into a plurality of segments, obtains a speed in a tangential direction of each of the divided segments, calculates a time taken for the tool to move on each segment, and obtains the total of the calculated times taken for the tool to move on each segment as a tool moving time, in order to calculate a time (tool moving time) taken for the tool to move on the designated tool path according to an NC command.

A controller to smoothly change speed of a machining tool to improve machining accuracy and speed of a machine. The controller includes a command analyzing section included in a block structure of software that analyzes a command program and converts it to data appropriate for use in a primary interpolation section. The primary interpolation section performs interpolation calculation in each first sampling period to obtain an interpolation point on a commanded path, and outputs the obtained interpolation point to an intermediate memory. The intermediate memory stores a motion amount for each axis, a feed rate and a block length. An acceleration/deceleration control section performs acceleration/deceleration control based on the data stored in the intermediate memory, and calculates speed in each second sampling period which is shorter than the first sampling period, to output the calculated speed to a secondary interpolation section. The secondary interpolation section defines a smooth curve expressed, for example, by a polynomial based on output from the acceleration/deceleration control section and the data in the intermediate memory, to output an interpolation point on the smooth curve in each second sampling period.

A method of teaching a robot motion program, which facilitates the preparation of programs, and in which a required one of a plurality standard motion programs for operating a robot in accordance with stereotyped motion patterns is read from a memory of a robot control device and displayed on a display screen of a teaching control panel. An operator operates the teaching control panel to add, though the display screen, position and speed data etc. to the standard motion program, or modify, through the display screen, the data previously described in the standard motion program, whereby a motion program for a robot operation to be performed in accordance with a sterotyped motion pattern or a pattern similar thereto can be created easily.
