The use of CNC machines is no witchcraft - assuming the software and control are adapted to the user's requirements.

Computer-controlled design and production with CAD/CAM has been no stranger to the natural stone industry for a long time - it is used to produce multi-piece kitchen worktops with drip channels, likewise richly decorated capitals. The computer is even on the advance in the preservation field, where it is used to scan damaged parts by laser, so that the new additions can be reproduced exatly to fit the broken surfaces of the original part.

Besides multi-axis machining centres and wire saws, more and more bridge saws are equipped with computer controls and integrated into the digitally controlled workflow. The standard among the design programs is AutoCAD. Special programs tailored to the requirements of the natural stone industry are easier to use and there are also special programs for the growing kitchen market. Every manufacturer of these follows his own philosophy, either by basing it on drawings previously designed in AutoCAD or by integrating a simplified drawing program into his software. This can be an advantage especially for users with no knowledge of CAD.

Which CAD/CAM program is recommended for the respective user depends on the user's training level and also on his requirements. According to the application, it may also be advisable to use a complete system, as offered by machines from the larger machinery manufacturers. (Stone Report, February 2005)
