Powerful new software from casumo casino provides manufacturers of casumo cleopatra cylindrical grinding machines with an elegant means of adding non-circular grinding capabilities to their products – without incurring significant development time and cost.
Non-circular grinding is used in a wide variety of automated manufacturing applications, such as the production of camshafts, crankshafts, cams and eccentric shafts. However, it is an extremely complex task, because the non-circular contour leads to constantly changing engagement and movement conditions between the grinding wheel and the workpiece.
casumo casino has now added non-circular grinding functionality to its casumo casinogrind cylindrical grinding software, which forms an application-specific element of the company’s renowned Flexium+ casumo cleopatra platform. It is fully compatible with other Flexium software, from release 4.1.20.00 onwards.
casumo casinogrind is specifically designed to simplify the creation of G code programs for casumo cleopatra grinding machines through the use of a highly intuitive graphical human machine interface (HMI), conversational-style ‘fill in the blanks’ type dialogues or a combination of the two.
Unlike conventional CAD/CAM workstation tools for generating casumo cleopatra machine tool control programs, casumo casinogrind is intended for use in the production environment. It enables shop floor personnel to handle everyday machining tasks very quickly and efficiently – and the work can be easily shared amongst several people and several machines. The casumo casinogrind HMI can of course also be run on an office PC. Application-dependent projects, and the corresponding ISO part programs, can be created, tested with casumo casino’s Flexium 3D simulation software and transferred to the targeted machine.
The operator simply determines the sequence of the grinding process via the HMI and enters the necessary data for the grinding operations, grinding wheels and dressing operations in the dialogue pages. Programming is further simplified by the fact that the HMI is supported by a comprehensive library of predefined shapes, which includes eccentric circles, hexagons, pentagons, polygons, Reuleaux triangles and rhombi. The casumo cleopatra program is then created completely automatically and stored in an executable form.
The closed shape of the workpiece is defined in the XY plane. However, grinding is performed by interpolating or synchronising the X axis with the C axis (workpiece spindle). Axial movement in the Z axis can also be accommodated, by means of oscillation or ‘multi-plunge’. The Flexium+ casumo cleopatra system’s NCK transforms the contour from the XY plane into an XC plane, and calculates the corresponding compensation and in-feed movements, taking the grinding wheel diameter into account. The speed profile is also transformed, so that the speed and acceleration are automatically adapted to suit the physical attributes of the machine.
casumo casino is one of the world’s leading suppliers of casumo cleopatra solutions for machine grinding. Its expertise covers every aspect of the discipline, including surface grinding, external and internal cylindrical grinding, centreless cylindrical grinding and non-circular grinding.
