procam（编程软件）

procam（编程软件） procam(编程软件) PROCAM is a 2D windows under punching system based on it, the graphical interface used to define the process route, when all parts processing route is given, which can be post processing, and then generate a NC processing program and tool files. One, CAD as part drawing, open the procam2d software, directly into the CAD system. In CAD, you first draw the parts that you want to program, which is the first step in software programming in cad/cam. For the parts design of the existing expansion graphics, only the graphics file type and format conversion cad/cam system acceptable file types and the ratio of 1:1, can be called directly, to the next step in die cam system. Two, cam shop layout mode, this step is the key process in cad/cam programming. The key of NC punching programming is laying mould, that is, selecting the proper mould and determining the proper punching process graphically. There are three modes of manual laying, automatic lay up, manual and automatic combination, laying, such as manual programming, automatic programming and semi-automatic programming. 1. manual programming programmers call the appropriate mold, hand along the CAD graphics inside and outside the outline of the mold into the cutting path, cam, the system allows manual insertion of single point, linear, arc, round and window mold path. 2. automatic programming system into cam, called die adapter command (toolfit), the system can search for files and turret mold library files, automatically invoke the appropriate mould, automatic calculation of punching machining sequence, and then insert the cam entity automatically to complete the processing of various workpieces die shop. Automatic adaptation, interference checking (interference, checking) and die tools (step) are also important. Interference checking means that the system checks the die adaptation entity to see if it has been cut. In case of excessive cutting, other moulds will be used. 3. semi automatic programming due to automatic mode shop limitations and some other reasons, the automatic spreading mode is sometimes difficult to get the best die adaptation, we can use a combination of graphical definition of manual mode and automatic mode shop shop to complete the work of the cam model, semi automatic programming. In punching, if we don't want to insert too many M00 pause instructions to pick up the workpiece or leftover material, here's a very important technique - inserting micro joins. Like 4. cam model in order to improve the production efficiency and the utilization rate of raw materials, reduce unnecessary waste of materials, and small punching must add clip bit parts, we can use cam model in the system of image, symmetry, matrix arrangement and copy function layout, workpiece workpiece processing (set three), commonly known as trepanning processing tool path optimization. For a single processing manual programming (no nesting, nesting parts), manual shop. At the same time, can be optimized, relocation and order of the mold processing path manually, like other automatic and semi automatic programming and nesting, nesting after punching to die blanking trajectory optimization processing. 1. optimization processing optimization processing is to optimize the cam processing trajectory order to reduce stamping time or make the distance between the shortest point and the number of tool change at least. Optimizations include: grid optimization, single, window, doubles, remove, gripper, quick motion optimization, and die sorting. 2. order ordering refers to the adjustment of tool stamping order, including: reorder, forward / backward (before/after), etc.. 3. reposition. Four, after the process (post), the tool path is optimized, and then the automatic post-processing can be carried out. After the processor will die cam model of blanking sequence and operation information created for the NC code, press run to run, the system will generate two files: NC files and setup sheet program (set plate) files, which are text files, you can use windows to provide text editor to read and write, edit and print operation. ProCAM is a two-dimensional punching system based on Windows, which uses a graphical interface to define the process path, When all parts of the processing route have been given, the post processing can be carried out, and then the NC processing program and the tool file are generated. Part drawings in CAD Open the ProCAM2D software and go directly to the CAD system. In CAD, you first draw the parts that you want to program, which is the first step in software programming in CAD/CAM. For the parts design of the existing expansion graphics, only the graphics file type and format conversion CAD/CAM system acceptable file types and the ratio of 1:1, can be called directly, to the next step in die CAM system. The rules for parts, such as electrical installation board, CAD/CAM can switch at the same time, the edge drawing while laying mode, even without drawing in CAD, can be directly carried out the coordinates of the center position of die hole with graphic definition in the CAM shop mode. CAD draw graphics, not CAD graphic layout, the layout of CAM is the best in the middle mold will CAM model as a whole layout process. Next, press the CAM button, and the system enters the CAM system from CAD. When you enter the CAM, you need to select the postprocessor (or control system) according to the actual NC machine tools, which is critical. Two, CAM shop mode and layout This step is the focus of the CAD/CAM programming process. The key of NC punching programming is laying mould, that is, selecting the proper mould and determining the proper punching process graphically. There are three modes of manual laying, automatic lay up, manual and automatic combination, laying, such as manual programming, automatic programming and semi-automatic programming. Before we die shop, according to the dimensional accuracy of parts, the size and position of tongs to determine, punching parts of the entire outer contour, or just rushed inside and outside contour, or red outline. This point will soon be established after proficiency. Secondly, the establishment of mold library Tool Library, will be used to mold and the loading mode set to standard file (such as Punch Files Tool die Tools turret tooling list file) and save up, can save the duplicate definition of commonly used mold steps in practical work. If the processor name is attached to the *.ptf suffix to save the mold file, enter the CAM system, open the corresponding post-processing control system, the standard mold library automatically opens, you can directly call the mold. Of course, you can also define the mold directly in the turret every machining part. 1. manual programming The programmer calls the appropriate mold and inserts the mold along the inner and outer contours of the CAD graphics. The CAM allows the system to manually insert single punch points, lines, arcs, circles, and window mold paths. The key to manual programming is to determine whether the mold goes along the inside or outside of the workpiece contour, that is, Tool Componsation. To determine the offset (Offset), through the blanking direction definition of mold insert entity Right boundary and Left boundary or Center, Right offset, Left offset, Center offset and End Compensation, No Compensation (end point compensation) (without compensation), Reference Compensation (reference compensation). In the punching die shop, to consider the stamping process and the workpiece rigidity to punching hole and choose the appropriate blanking sequence, such as the first flush after internal external, punching hole after hole etc.. In large complex blanking plate, to call more die, in view of the actual mold number, size, machine tool turret rotating position limit, we'd better make the whole die in the shop before the overall consideration, in order to avoid trouble halfway die shop. For the processing of super long plate, it is necessary to re position the blanking piece. 2. automatic programming In CAM system, called die adaptation command (Toolfit), the system can search for files and turret mold library files, automatically invoke the appropriate mould, automatic calculation of punching machining sequence, and then insert the CAM entity automatically to complete the processing of various workpieces die shop. The key here is to choose the appropriate Inside Toolfit (on die adaptation) and Outside Toolfit (foreign die adaptation), to enable the system to identify external entities of the workpiece edge, while the internal composition of the workpiece edge which entities, in order to allow the system to determine which side to be processed. The key is to set the automatic programming, die InforBar information bar right in the adaptation parameters and Punch parameters (stamping parameters), as can be used for the size of the minimum or maximum allowed value, optimal die width, best flatness and the best roundness, the better for the size, or the maximum and minimum value of arch cutting parameters Pitch (pitch), of course, by default (default) value, but not necessarily optimal. Automatic adaptation, interference checking (Interference, Checking) and die Tools (Step) are also important. Interference checking means that the system checks the die adaptation entity to see if it has been cut. In case of excessive cutting, other moulds will be used. If the mold is not found, the system shall not be adjusted to the interference parts. When the die step commands, each entity of the workpiece is matched with the die step by step, the selection of several dies and dies for the entity is displayed so that the programmer can select the best die fit. 3. semi-automatic programming Due to the limitations of the model of automatic laying and some other reasons, the automatic spreading mode is sometimes difficult to get the best die adaptation, we can use a combination of graphical definition of manual mode and automatic mode shop shop to complete the work of the CAM model, semi automatic programming. In punching, if we don't want to insert too many M00 pause instructions to pick up the workpiece or leftover material, here's a very important technique - inserting micro joins. Micro connection has angle micro connection and unilateral micro connection two kinds. Angle micro connections are used to define the two side connections, i.e., the micro junctions at the sharp corners; the unilateral micro links define the single sides of the material (edges). Since the micro join can only be inserted at the endpoint, the CAD element can be broken and inserted into the micro connection at the point where additional CAD is attached. The type and size of the micro connection can be defined with shape function (Shape) in the CAD system, and then the Insert Point command is used to insert the appropriate Micro Joint (the micro connection) at the straight end point of the micro connection. Layout of 4. CAM model In order to improve the production efficiency and the utilization rate of raw materials, reduce unnecessary waste of materials, and small punching must add clip bit parts, we can use CAM model in the system of image, symmetry, matrix arrangement and copy function layout, set of workpiece workpiece processing (commonly known as Trepanning Processing). The layout of blanking can be taken in several ways as shown in Figure 1 to figure 3. Figure 1 double row single blanking layout Fig. 2 double row blanking layout After nesting and layout, the system Set and Information can be set up, including sheet size, clamp position and so on. If the workpiece (workpiece assembly) is not positioned correctly on the plate, use the Move command to move the workpiece to the appropriate position of the plate. The clamping position can be carried out during the laying of the mould, and the position of the clamp is defined graphically so that the dead zone of the clamp can be understood immediately, visually and accurately. Figure 3 cutting and layout of cutting edge Three 、 tool path optimization For a single processing manual programming (no nesting, nesting parts), manual shop. At the same time, can be optimized, relocation and order of the mold processing path manually, like other automatic and semi automatic programming and nesting, nesting after punching to die blanking trajectory optimization processing. Including optimization (Optimization), utility (Order), or Reposition, etc.. 1. optimization treatment Optimal processing is to optimize the order of CAM machining trajectories to minimize stamping time or minimize the distance between points and the number of tool change. 优化包括:栅格优化(网格优化)、单个视窗优化(单窗口)、除双优 化(除去双打)、避开夹钳快速移动优化和冲模分类调整等。 2。次序化 次序化是指调整刀具冲压加工次序，包括:重定义次序(订货)、前 移/后退(前/后)等。 三.重定位 重定位是对超出机床工作区的板材重新定位，以便对板材进行更多的 冲压加工。 四、零件的后处理(后处理) 刀具轨迹优化处理完后，便可进行自动化的后处理。后处理器将凸轮 模型中模具冲裁顺序和操作信息创建为数控程序代码，按下运行运 行，系统将生成两个文件:数控程序文件及安装(设置板材)文件， 它们都是文本文件，可以使用Windows提供的文本编辑器进行读写、 编辑和打印操作。
