    • The invention provides a software development support system capable of reflecting the content added by a person to source code in source code generated again, without modifying design information. A generator 41 generates source code in which plural insertion markers are inserted on the basis of design information. An extracting portion 43 extracts code (inserted code) contained in a range specified by each insertion marker in source code. Each extracted inserted code is associated with its identification information and stored into a saving portion 32. When the generator 41 generates source code, a combining portion 44 performs a process of combining inserted code with the relevant source code and outputs the processed source code, wherein the relevant inserted code is included in plural pieces of inserted code stored in the saving portion 32, source code identified by the identification information for the relevant inserted code coincides with the relevant source code and an insertion marker identified by this identification information exists in the relevant source code and coincides with the relevant insertion marker.
    • 本发明提供了一种软件开发支持系统,其能够将人们添加的内容反映到源代码中,而不再修改设计信息。 发生器41基于设计信息生成其中插入多个插入标记的源代码。 提取部分43提取包含在源代码中由每个插入标记指定的范围内的代码(插入代码)。 每个提取的插入代码与其识别信息相关联并存储到保存部分32中。 当发生器41产生源代码时,组合部分44执行将插入的代码与相关源代码组合的处理,并输出处理的源代码,其中相关的插入代码被包括在存储在保存部分32中的多个插入代码中 由相关插入代码的识别信息识别的源代码与相关源代码一致,并且由该识别信息识别的插入标记存在于相关源代码中并与相关插入标记一致。

    • 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.
    • 控制器可以平滑地改变加工工具的速度,提高机床的加工精度和速度。 控制器包括一个命令分析部分,其包括在分析命令程序的软件的块结构中,并将其转换成适合于在主要插值部分中使用的数据。 主插值部在每个第一采样周期中执行插值计算,以获得指令路径上的内插点,并将获得的插值点输出到中间存储器。 中间存储器存储每个轴的运动量,进给速率和块长度。 加速/减速控制部分基于存储在中间存储器中的数据执行加速/减速控制,并且计算比第一采样周期短的每个第二采样周期中的速度,以将计算出的速度输出到二次插值部分。 二次插值部分定义了例如基于加速/减速控制部分的输出的多项式和中间存储器中的数据表示的平滑曲线,以在每个第二采样周期内在平滑曲线上输出插值点。

    • A feed speed control method for a numerical control device in which a feed speed of a tool traveling along an instructed machining path is controlled in accordance with a machining program. The speed of each axis is derived (S2), and the acceleration of each axis is derived from a speed variation between adjacent blocks (S3). When the acceleration (.DELTA.Vx) is larger than a permissible acceleration (.DELTA.Vxmax) (S4), first ratios (K1) of the permissible accelerations to the accelerations are derived for individual axes (S5), and the smallest of the first ratios is selected. The command speed is multiplied by the square root of the smallest first ratio to derive an actual feed speed (S9). In this way, shock to a machine is reduced and an excessive load on a servomotor is reduced even when blocks continue for successive infinitesimal distribution distances, as in the case wherein a curve is approximated by the use of straight lines.
