ProCAM CNC punching Programming

http://www.soft6.com/html/tech/6/61118.shtml

ProCAM is based on Windows, two-dimensional impulse processing system that interfaces with the graphical definition of process route, when the parts are given all the processing line after the post-processing can be carried out, and then generate NC machining process and tool files.

1, CAD as part of plan


Open ProCAM2D software directly into the CAD system. In CAD, the first part draw graphics to programming, which is CAD / CAM software programming in the first step. Expand the existing part design for graphics, just the graphics file types and formats into CAD / CAM system can accept the file type and 1:1 ratio, you can directly call into the shop next CAM system model.

The rule parts, such as electrical installation panels, CAD / CAM can also switch to that side of Paint Shop mold side, and even some not in the drawing in CAD, CAM can be used directly in the center of the hole location coordinates of the graphical definition of mold for shop mode. CAD in drawing the graphics, do not carry out CAD graphics layout, best layout is laid out in the CAM in the CAM model will die as a whole and layout processing.


Next, press the CAM button to enter the system did give CAD CAM system. Into the CAM, you need the actual use of CNC machine tools, selection processor (or control system), it is critical, not the wrong.

Second, CAM in the shop mode, layout


This step is a CAD / CAM programming focus of the course. CNC Punching programming, the key is to shop mode, choose the appropriate mold, graphical way to determine the appropriate blanking line. Shop shop model with manual mode, automatic mode and manual and automatic shop combined shop model in three ways, also known as manual programming, automatic programming and automatic programming.

Shop model, we first according to the dimensional accuracy of parts, specifications such as size and location of clip-clamp to determine, is the internal and external contours of stampings, or only red part of the inside and outside the contour, or outline of red. Skilled after this quickly determine the. Second, the establishment of die Library Tool Library, will be used to set the mold and loaded as a standard mold file Tool Files (such as Punch Tools turret tooling inventory file) and save them, in practice the definition used in the mold can be avoided to repeat the steps . Processor name, such as to save the die attach *. ptf file extension into the CAM system, open the appropriate post-processing control system, the standard mold library automatically open, you can directly call the mold. Of course, you can process a part of each turret is defined directly in the mold.

Expand the existing part design for the graphics, just the graphics file types and formats into CAD / CAM system can accept the file type and 1:1 ratio, you can directly call into the shop next CAM system model.


Manual programming, the key is to determine the mold along the workpiece contour to go inside or outside that mold offset compensation (Tool Componsation) problem. Determine the offset (Offset), the direction defined by blanking die insert entities, Right Side, Left Side or Center, to Right offset, Left offset, Center offset and End Compensation (end compensation), No Compensation (without compensation), Reference Compensation (refer to compensation), etc..
The rule parts, such as electrical installation panels, CAD / CAM can also switch to that side of Paint Shop mold side, and even some not in the drawing in CAD, CAM can be used directly in the center of the hole location coordinates of the graphical definition of mold for shop mode.

Next, press the CAM button to enter the system did give CAD CAM system. Into the CAM, you need the actual use of CNC machine tools, selection processor (or control system), it is critical, not the wrong.

Shop in the blanking die, consider blanking process and workpiece rigidity strength to increase Punching and choose the appropriate blanking sequence, such as the first impulse after the impulse within the external, the first impulse after the impulse large holes and other holes. Blanking plate complex in the bigger, the more mold to call, given the number of actual mold, size small, machine tool station turret rotation limit, we'd better do a good job in the shop before the model to consider the overall situation in order to avoid mold shop halfway there trouble. Long sheet of processing required to reposition the workpiece blanking, die shop manual repositioning of the location should be considered.

Second, CAM in the shop mode, layout
2. Automatic Programming

Into the CAM system, called die adapter command (Toolfit), system files, and die on the turret to search library files automatically call the appropriate mold, automatic calculation of punching the order, and then automatically insert the CAM entities to complete the processing of the mold shop kinds of artifacts. The key here is to select the appropriate Inside Toolfit (internal die adapter) and Outside Toolfit (Foreign die adapter), so the system can identify which entities external side of the workpiece, the workpiece and which entities within the side to allow the system to determine Which side should be processed.

Determine the offset (Offset), the direction defined by blanking die insert entities, Right Side, Left Side or Center, to Right offset, Left offset, Center offset and End Compensation (end compensation), No Compensation (without compensation), Reference Compensation (refer to compensation), etc..
Automatic programming focus, set the correct InforBar information bar die adapter parameters and Punch parameters (stamping parameters), such as die size can be used to allow the minimum or maximum value, the optimal die width, the best degrees and best flat roundness, optimum die size, or maximum over all parameters, the minimum arch value, Pitch (pitch) and, of course can be the default (default) value, but not necessarily optimal.


Shop in the blanking die, consider blanking process and workpiece rigidity strength to increase Punching and choose the appropriate blanking sequence, such as the first impulse after the impulse within the external, the first impulse after the impulse large holes and other holes. Blanking plate complex in the bigger, the more mold to call, given the number of actual mold, size small, machine tool station turret rotation restrictions, we had better die in the shop the whole situation into account before doing so shop mold halfway there trouble. Long sheet of processing required to reposition the workpiece blanking, die shop manual repositioning of the location should be considered.

2. Automatic Programming

Auto Adapter, the interference check (Interference Checking) and die step (Step Tools) are also important. Interference checking, is the system fit the mold entities to check to see if there were cut. If over-cutting, will choose other mold. If not find a suitable mold, the system does not interfere in part to die adapter. Die step command, every entity on the work piece, step by step die adapter, the display for the entity dies and die several track options for the programmer to choose the best fit die.

3. Semi-automatic programming

Auto Adapter, the interference check (Interference Checking) and die step (Step Tools) are also important. Interference checking, is the system fit the mold entities to check to see if there were cut. If over-cutting, will choose other mold. If not find a suitable mold, the system does not interfere in part to die adapter. Die step command, every entity on the work piece, step by step die adapter, the display for the entity dies and die several track options for the programmer to choose the best fit die.


As the auto-shop model limitations and other reasons, the auto shop die mold is sometimes difficult to get the best fit, we can combine the use of manual mode and auto-shop model shop to complete the graphical model of the workpiece definition of CAM, to achieve semi-automatic programming.

In the punching process, if we do not want to insert too many M00 suspension parts or instructions to take away more than expected, then, there is a very important skill - into micro connection. Micro-micro connections and the connection with unilateral micro-angle connection of two. Point connection is used to define both sides of the micro-junction, that is, micro-angular Department connection; unilateral definition of micro-entity connection (edge) side of the micro-links. As the micro-endpoint connection is only able to insert, so I can prepare in CAD graphics after the junction For additional unilateral micro-break factor in CAD, insert the micro connections. The type and size of micro-connections can be used in the CAD system, the shape function (Shape) definition, and then use the Insert Point command line to set up micro-endpoint connection, insert the appropriate Micro Joint (Micro-connection).

4. CAM nesting model

In order to improve production efficiency and material usage, reduce unnecessary waste of materials, processing the smaller and the red folder to place additional parts, we can use the system image, symmetric, matrix array, and copy functions such as CAM model layout, workpiece set workpiece processing (commonly known as nesting processing). Blanking can take the form of nesting Figure 1 Figure 3 shows several ways.
