Why Peace?Peace: Run your machining with the usual ease with which print a document!

When we decided in 1982 to produce our first machine center, together with the design of the machine, we started with the development a conversational programming system easily suited to create also unique pieces.

The machine operator is not required to learn the ISO code programming, especially if created Parametrically, reaches such levels of complication to be hardly justifiable.

Starting then from the demands of the individual operator, the difficulties encountered in the rea-lization of the single piece, macro after macro option after option we managed to put together a complete programming system and at the same time simple and friendly to the operator.

Small/medium machining complexity can then be performed directly with our software on the ma-chine or possibly installed (this free of charge) on one or more PCs in your corporate network.

For complex processing of course the use of a structured CAM is recommended without this has reduced the importance of our soft, indeed has improved in that allows greater integration between your Cam and CN.

With the slides that follow, that were created with version 2.5 by March 2013 from our program, we try to give a very quick idea of what we did. For those interested in deepening the topic must necessarily proceed with an individual demo which could be done remotely in Telecare.

Initial ConnectionBasic PhilosophyOur machines are characterized in that they have two PCs. The first, normally not accedibile by the end user, is used for the control of the axes and the machine logic. The second, this instead ac-cedibile by the end user, is used to proceed with the programming of the machine. These two PCs are distinguished one another and exchange data via the protocol TCP/IP. This separation adds a lot of confidence in using the machine. Even if the PC used for programming of the processing should have a fatal “crash”, the axes of the machine will continue to be monitored regularly. The Pc used in programming is also a Pc whose OS is completely standard and then you can install other programs besides ours, such as CAD/CAM, without ever going to catch on the real-time ma-nagement of the machine axes. The fact that it is technically possible to install our program, such as under Windows 8, even on our 1992 machine derives from the fact that there are two PCs and each of which can have its history and evolution different from each other.

Initial ConnectionWe have said that the two PCs are sharing data via TCP/IP. For those who don’t know the TCP/IP protocol is the Internet protocol. This means that the PC that controls the machine can commu-nicate beside with the PC located on the machine, even with your other PCs in your LAN (“Local area network”) located for example in your technical department. It is a service widely used by our customers as you can program your machine, while maybe it’s doing a different job, from a “remote” position. If you have multiple machines from the PC “remote” then you will have to de-cide to which machine you want to connect. The Pc that controls the machine can communicate with multiple PCs “remote”. Thanks to this configuration if you put up your “VPN (Virtual Private Network) from any Pc that has access to the Internet (e.g. from home), you will be able to see what your machine is doing.

NC Command ExecutionPhilosophy of Numerical Control Commands ExecutionEven in this case, for each command which the operator must perform, it was foreseen the relative programme. So there’s never the need to have to input a command in ISO code. So we have a total of over 20 programs.

Geometry File ImportAlthough there is a Cad 2d within our program, it is clear that most of the performed operation will result from importing geometry file programmed by external Cad/Cam and this especially in the case where processing should be performed 3 or more axles.

There are the following import filters:

For 2 axis machining:- .Dxf Files

- .Sca (Scanvec Casmate)

- .Iso (for various Cad/Cam programs)

For 3 axis machining:- .Iso- .Stl

For 5 axis machining:- .Iso only

2D CadThis is a 2D Cad itself that has been added to our program only at the end of 2009. It has some features that differ from the majority of 2D Cad on the market and in particular:

- Unlimited Undo/Redo and on file. In other words you can reopen an old project and trace back all steps of programming and then, if deemed appropriate, do it again.

- For basic commands is available the parametric programming. For example, if on a profile were rounded up by a certain edge fillet radius, you can then repeat this rounding operation simply by setting a new value of fillet radius.

- Very sophisticated layer Management (also called in other Cad groups, collections, levels)

Files stored with this program can then be processed by our Cam and sent working directly without requiring any import operation or post-processing

Generating 3D Geometry File3D toolpath generationIt is a set of performance, programmable in an extremely simple way, already available from the mid-90s, with which you can:

- Depositing an engraving on a surface 3d copied or imported in ISO code, or on a concave sur-face, convex, spherical, toroidal or defined by an inclined plane.

- Generate a 3d solid by extrusion or rotation

- Make the radius compensation of a 3d surface copied or imported in ISO code. In the case in which the surface to compensate has been copied is also possible to set a filter to “clean” the data to compensate

- In recent times we have also begun to accept as input .Stl file on which we are currently able to make only the compensation radius for parallel passes

Tracing ProgramsAlthough the evolution that took the 3d Cad in recent years reduced the use, there is a very com-prehensive program to make copying of a template.

You can set the execution in automatic sequence of multiple rounds of copying and if a pallet changer or robot loading units to replace the copy template automatically.

There is also the whole soft to get automatic development of shoe models between different sizes. This program can be advantageously used also in the case where the model to be graded has been programmed with an external CAD/CAM.

Work MemorizationSaving the Program of Work to be Carried OutIt is the most fundamental program with which the machining is programmed. The machine will then execute what planned.

Countless are the programming parameters, but all in clear and so there is no special code to learn how it happens in the programming of standard numerical control machines.

Any modified parameter enter immediately. For example, if a macro must be milled with five passes vertically instead of four, simply change its parameter and the machine will be ready IMMEDIATELY to run the program with five passes.

25

SW PEACE

Work Memorization: Initial ParametersAllows setting of all the parameters that are valid for the whole execution of the process. For exam-ple to set the size of the piece in such a way that if it is set a processing outside of these values, the program immediately report the programming error committed.

From a careful reading of the slides above is already possible to get an idea of the amount of processing parameters can be set and ease of programming.

Work Memorization: Macro SelectionAre available to the programmer as many as 26 different macros where each of which had its software development originated, in most cases, by specific requirements of end users received in over thirty years of use.

Apart from the fundamental macro @ FIL of which is shown a detailed example, there are macros to be able to engrave texts, perform flattening, drilling holes/tapping with a number of processing parameters available remarkable. All with the possibility of being able to perform such processings over surfaces defined by a set of different methods and this with the macro @ C3D.

Obviously we can not silence the macro or @Z32 or @5D used to send in processing the files gene-rated by your Cam while retaining the ability to change the processing parameters in a very simple way and finally the macro @ REP to repeat one or more times a certain set of program lines.

- A further macro @FIL to carry out the pocketing residual, this time with a tool of a much smaller diameter, only in areas where the old tool could not remove the material having a tool diameter too large

Tool FilesTool identificationUnlike the vast majority of work centers on the market, the programming tool type chosen is NOT identified by the number of tool pocket, but from a file name directly set by the operator.

The attached slides show the main parameters of a default tool file, named “OTN\ FrC\01_00″, which corresponds to 1 mm diameter cylindrical tool suitable for the machining of brass.

Of course it is also possible to mount more machine tools with the same name and be called se-quentially in the event that, through the use of the preset tool length, has been detected the rupture or excessive wear.

File Sharing Tools between Multiple MachinesIf you have multiple machines you can share files between all your machines tools in such a way as to call the usual tool with the same name on all your machines. Special safety regulations allow the continuation of regular if for any reason the server on which you have stored the files tool should cease to operate regularly.

Work ExecutionExecution of a Single WorkOnce stored a work, with this program can then be executed.

If the working should not be performed from the beginning, there are commands to be able to resume the work from where it was interrupted.

There is the possibility of being able to send, when the work has been performed regularly or has stopped for any cause, an e-mail message to a predetermined address.

A very powerful system allows then to store the actual work time according to an order, and other parameters in order to satisfy every possible need of industrial accounting.

Set of WorksExecution of a Series of WorkingThis program is a real supervisor with whom you can send in work one or more programs.

If present a device for feeding pieces automatically, it will be possible to select the piece relative to send in work and in assigning possibly also a number of different origin than that originally provided by such processing.

It is also possible to apply the factors of symmetry on the work involved and if there is the neces-sary hardware it is also possible to be sure that the program assigned the execution of a single work is compatible with the dimensions of the piece sent in the works. About this performance were developed control systems different from each other in relation to the types of processing to be performed.

This program is used frequently even if there is no auto-mount device of work piece. In this case, are mounted on the working table several pieces to be performed on various number of origins and then thanks to this program will be executed sequentially.

If during the execution of the manufacturing one or more tools were no longer available due to breakage or excessive wear, this program will continue to send in work programs that include the use of tools still intact even if programmed, in the sequence of machining operations to be perform, in one of the following positions.
