Direct processing of codes G in the unit of control of the robot thanks to the core CNC integrated

Although it is true that existed and exist a lot of systems for the off-line programming of robots based in CAD/CAM, what was missing was the homogeneity of the data until the unit of control of the robot. The basic requirement for the processing of the programs was, until the moment, the conversion of the programs CNC to the respective language of the robot with help of a posprocesador adapted. The loss of information was not at all unusual, since always there were functions of the program CNC that were not compatible with the distinct languages of the robot.

Thanks to Kuka.CNC No longer exist limitations. The direct integration of the core CNC in the unit of control of the robot allows to endow to the system of mechanised robotizado of additional functions, directly of factory.

Kuka.CNC Allows to process programs CNC directly with the unit of control of the robot according to DIN 66025. Kuka.CNC Interprets the complete rank of standard codes and the robot carries them to the practice (work G, functions M/H/T, subprogramas local and global, structures of instructions of control, loops, etc.). In this way, the field of application of the industrial robot sees expanded, especially, with the following functions:

• Milled of pieces of forming of soft material/semiduro as, for example, wood, plastic, aluminium, compound materials, etc.
• Polishing and rectified of pieces of forming
• Coating and treatment of complex surfaces
• Riveting and court of pieces and complex outlines
• Cut by laser, plasma and chorro of water of complex pieces

Thanks to the direct integration of the core CNC in the unit of control of the robot, the robot turns into a machine of mechanised with cinematic open, that combines the advantages of an industrial robot (wide field of work, high flexibility, low costs of investment, mechanised with 6 axes) with the ones of a control CNC (programming of codes G, interface of user CNC, compensation of the radius of the tool, previous sight of the points, calculation spline of the path and comfortable administration of the tools).

The integration of the core CNC allows besides process the program CNC directly in the unit of control of the robot. Like this, so many programmers of CAD/CAM like operarios of CNC will be able, with his knowledges, to program and handle an industrial robot.

The way CNC comports big advantages especially for processes of path. Thanks to the core CNC and his subfunciones, the programs of mechanised with big number of points of path can process with greater accuracy and cycles shorter. The improvement of the precision and the reduction of the times of cycle are the result of the functions expanded that it has the core CNC to schedule the path. The possibility to obtain a previous sight of until 500 points during the planning of the path allows to the robot keep constant the speed during the mechanised and schedule the rampas of acceleration and braked of optimum form. Also the precision of path sees improved by diverse interpolations spline carried out in the core CNC. The methods Akima and B-Spline guarantee that the robot effect the precise follow-up of the path programmed. The functions CNC typical combine with the conventional functions of the unit of control of the robot, allowing obtain a result of mechanised optimum.

The fact to be able to process codes G involves also a redesign of the employment of robots in the surroundings of machines of mechanised CNC conventional. In installations of mechanised automated will be able to employ, together with the machine-tool, also a robot whose programming and handle will be able to realise according to the code DIN 66025. This facilitates the integration of the robot and offers essential advantages for the operario of the machine, since it no longer will have to have of knowledges of specific programming of robot, but his knowledges of CNC will be sufficient to handle also the robot.

A special case of the mechanised automated is that in which the robot occupies of the mechanised of the pieces. The combination of mechanised and manipulation does that this type of process was especially efficient. Since the robot occupies to collect the pieces, transport them to his place of mechanised and transfer them to a system of storage, is possible prescindir of cinematic of transport and manipulation in the automation of the process. The machine of mechanised and the installation of automation merge forming a unit, what repercute of decisive form in the profitability.

Thanks to the programming CNC, open new systems of programming for the robot. The market of systems CAD/CAM offers special solutions for numerous applications of mechanised. This goes to carry, in the future, to a multiplication of the possibilities of programming and application of the robots. Increasingly systems CAD/CAM recognise this tendency and endow to the systems of software of special modules for the programming of robots and the simulation.
