Most high-end CAM system programmers typically retreat when discussing CNC-based parametric programming issues. Most programmers need to clean up the output, and these outputs will run in the CNC without modification - some of the parametric programming applications may actually break the work if not properly applied.

There are five types of application for parameter programming. I think that if you use the CAM system to generate CNC programs, some of them do not apply.

1. The family of workpieces - a number of workpieces are machined with a parameter program, and the operator changes the variables on the machine to characterize the workpiece being machined.

Most CAM systems also have their own family of programming capabilities, and many CNC users do not want their operators to manipulate programming. Therefore, CNC-based workpiece family parameter programming is usually not a good application for CAM system users.

This seems to be a classic parametric programming application type, but it is also the most problematic type for CAM system users. Workshop workers like to be able to master the operation. If only a few variables are changed, different workpieces can be created. They are definitely welcome. In fact, many application families of applications are too complex, and their parameter programming is difficult to master, especially when the work itself is complex and requires the CAM system to generate programs.

2. User-created closed loop - a series of motions can be performed from a G-level instruction

Most CAM systems can utilize CNC-based closed loops (such as hole machining cycles on machining centers - G81, G84, etc.). That is, the actual output program of the CAM system will include closed loop instructions, which are part of the post processor. These built-in, CNC-based closed loops shorten the program and make it easy to modify.

If your company often does some type of processing and does not go through a controller-based closed loop, then you can create your own closed loop, modify the post-processor of the CAM system, and output the appropriate instructions. carry out. The best example is machining the thread with a machining center. Many CNCs do not have a closed loop for milling threads, and parameter programming makes it easy to create a closed loop. Once created, it can provide all the advantages of any other closed loop and can be executed by the CAM system (if the post processor is modified). On the machine, the program becomes shorter and the operator can better control the machining of the threads.

3. Utility program - the performance of CNC machine tools has been improved and improved to some extent

This type of application is useful for all CNCs, including those with CAM systems. In general, when your machine has a problem, you should consider using the utility parameter program to improve the performance of your machine.

The CAM system is not involved when using many utility applications - what needs to be modified is the way the machine operator operates. For example, to measure the zero program (original) task, if the setting is qualified, then this task does not need to be done. Zero program can be calculated, and zero program delegate instructions can be included in the program. If a qualified setting is not possible, the position of the zero program must be measured during the setup process. One method is to use a measuring rod probe driven by a parametric program. If the machine does not have a measuring rod probe, the setup personnel should manually measure the position of the zero program point using gauges such as edge detectors and scale indicators.

4. Drive Auxiliary Device - The application can drive the probe, as well as track, report and post-process the detection system

This high-end auxiliary device requires parameter programming features. If a machining center has a measuring rod probe, there may be parameter programming capabilities as well. Because the probe can be programmed, you can think of this as similar to a so-called user-created closed loop. One or more probe cycles are often included in the CNC program, and the CAM system must be able to output the necessary instructions.

5. Complex movements - new (or optional) forms of movement can be created

The controller manufacturer will provide a variety of insertion procedures for the desired motion, the most common being linear, circular, spiral and other insertion procedures. If you encounter a motion mode machine that cannot be performed, the parameter program can be solved. Note that many CAM systems can produce almost any type of motion, but the corresponding CNC program can become lengthy - its CAM system must produce a long series of tiny, straight or round motion commands.

When milling threads, a helical insertion movement is required. So far, many new machine tools have not yet provided a screw insertion program, and older machines do not. The parameter program produces the helical motion required to mill the threads. This type of application is generally much shorter than the program produced by the CAM system.
