[0004] 现阶段用于型钢切割的机器人离线编程技术大多存在以下缺点：1)型钢切割特征建模复杂，不适合工人操作；2)切割坡口角度在一侧型钢表面上只能设定固定的坡口值，不能进行变坡口切割；3)在角钢、球扁钢等的切割中两个型面相交棱角处切割质量较 [0004] Present robot off-line programming techniques for steel cutting of most of the following disadvantages: 1) modeling of complex steel cutting characteristics, is not suitable for workers to operate; 2) cutting bevel angle on the side of the steel surface can only set a fixed The groove values ​​and can not be changed beveling; 3) the intersection of the edges and corners cut quality angle, the ball flat steel cutting two profiles compared

差，需要进行人工二次加工等。 Poor, the need for artificial secondary processing.

[0028] 图2为本发明一个优选实施例的用于型钢的机器人切割方法示意图。 [0028] Figure 2 embodiment of the present invention, the steel for a schematic view of a preferred embodiment of robot cutting method.

[0029] 例如在本发明的实施例中，使用第三方CAD产品如AutoCAD、TRIBON等，绘制型钢切割所要求的切割图形，并以指定格式文件存储。 [0029] For example, in an embodiment of the present invention, the use of third-party CAD products such as AutoCAD, TRIBON, etc., required to draw steel cutting cutting pattern, and files are stored in the specified format. 然后利用特征建模模块将图形文件打开， 对文件进行编译，提取文件的图形特征，并进行基本图元分解。 Then use the feature modeling module graphic file open, compile the file, extract the graphic signature file, and perform basic elements exploded. 通过参数设置界面，将依次对基本图元进行放置面、坡口类型、坡口参数等信息的设置，构建切割特征，并以切割特征文件形式保存。 By parameter setting interface, turn on the basic elements were placed face groove type setting information, groove parameters, build cutting characteristics, and to cut features saved as a file. 此切割特征文件将放入型钢切割特征库中。 This profile will cut into steel cutting feature library. 若型钢切割特征库存在所需的切割图形或相似图形（图元组成相同，但尺寸不同），则可以免去上述步骤，直接进入单元编程模块。 If the steel stock cutting characteristics desired cutting pattern or similar pattern (composed of the same elements, but in different sizes), you can avoid the above steps, directly into the cell programming module.

[0030] 在单元编程模块中，通过调用型钢切割特征文件来导入切割特征，如要对切割特征进行部分更改，可根据需要对切割特征进行参数驱动，包括位置驱动（更改切割特征的放置位置）、图形尺寸驱动（更改切割特征中的图形尺寸）和坡口驱动（更该切割特征中坡口参数），以满足实际切割要求。 [0030] In the cell programming module, cut the signature file to import steel cutting by calling features, such as to be part of the cutting characteristics change, may need to cut parameter-driven features, including the location of the drive (to change the placement of the cutting characteristics) graphic dimension driven (Change cutting feature graphics size) and bevel drive (more features in the cutting groove parameters), to meet the actual cutting requirements. 将调整好的切割特征进行路径规划，完成整个切割单元的建立。 The good cutting characteristics adjustment path planning to complete the establishment of the entire cutting unit. 仿真子模块建立了型钢的三维仿真模型，并对切割单元特征进行编译，生成中间数据。 The establishment of a sub-module simulation model of three-dimensional simulation of steel, and features cutting unit compiled to generate intermediate data. 依据此中间数据，一方面将型钢切割的套料进行多角度显示，另一方面以三维动画模拟机器人末端切割枪的运动过程，方便用户观察，检查运动的合理性。 According to this intermediate data, on the one hand the steel cut nesting multi-angle display, movement on the other hand to the end of the three-dimensional animated simulation robot torch, user observation, plausibility checks movement. 最终将完成的切割套料文件以型钢切割套料文件的形式存储。 Cutting nesting final document will be completed in the form of steel-cut file storage material.

[0031] 例如，在上述机器人切割方法中，将型钢切割特征文件转化为机器人程序对型钢进行切割步骤包括：调用切割单元特征文件，并按照工艺要求通过参数设置界面接收对切割的工艺参数进行设置或通过查表方式确定最优化的参数；根据型钢的整体长度以及设定的切割单元间的相邻距离，确定切割单元编排数目，形成型钢切割文件；对型钢切割文件进行编译，生成机器人运动的控制命令和位姿数据，并按照机器人的执行程序要求的输出程序，机器人执行输出程序对型钢进行切割。 [0031] For example, the robot cutting process, the cutting beam profile into a robot program for steel cutting step includes: cutting unit calls the signature file, and follow the process requirements through parameter setting interface to receive cutting process parameters set or to determine the optimal parameters by look-up table; according to the distance between adjacent steel and the overall length of the cutting unit set between the choreography determine the number of the cutting unit, forming a beam splitting files; steel cutting files are compiled to generate a robot movement control commands and the position and orientation data, and execution of the program in accordance with the requirements of the output of the program the robot, the robot program execution steel output cut.

[0032] 机器人在型钢上的连续性切割操作通过套料编程模块实现。 [0032] The robot continuity in the steel cutting operations through nesting program modules. 套料子模块中，用户导入所需的切割单元特征文件，并按照工艺要求利用参数设置界面对切割的工艺参数（如切割速度、切割电流、气体流量）进行设置，也可以由程序利用查表方式进行参数最优化确定。 Jacket material module, users import the cutting unit profile and follow the process requires the use of parameter setting interface for cutting process parameters (such as cutting speed, cutting current, gas flow) are set, you can use look-up table by the program parameter optimization OK. 根据型钢的整体长度以及切割单元的相邻距离（由用户确定），可确定切割单元编排数目。 (Determined by the user), the number can be determined according to the overall length of the arrangement of the cutting unit and the distance between adjacent steel cutting unit. 最终形成型钢切割文件。 Eventually forming steel cutting files. 后置处理模块调用型钢切割文件，进行编译，生成机器人运动控制命令和位形数据，并按照机器人执行程序要求，输出程序。 Post-processing module called beam splitting files, compile, generate robot motion control commands and data bits form and follow the robot execute the program requirements, the output program. 同时根据切割工艺信息，输出其余切割设备的控制信息。 According to information at the same time cutting process, the remaining control information output cutting equipment. 因为有时候切割特征单元较复杂，生成的机器人执行程序过大，超出了控制器的允许范围，此时后置处理模块可智能地在可停顿点除将超大程序进行分割，并自动添加用户坐标系等机器人执行程序附属信息，形成系列化的型钢机器人切割执行程序。 Because sometimes cutting feature cell is more complex, generated robot program execution is too large, beyond the permitted range controller, then post-processing module can intelligently can pause point in addition to the very large programs divided, and automatically add user coordinates Department and other robot execute the program attached information to form a series of steel robot cutting the program.

[0033] 从上述描述中可以看出，本发明的上述实施例实现了以下有益效果： [0033] As can be seen from the above description, the above-described embodiments of the present invention achieves the following beneficial effects:
