This guideline is intended to provide assistance in understanding how the results of grinding can be specifically influenced by the selection of the parameters and other important input variables in dressing and trueing. VDI 3392 Part 1 primarily concentrates on providing basic information about dressing. It also gives decision-making aids indicating which dressing processes and tools would be appropriate for which grinding wheels and grinding materials, here taking into account the material which the component to be ground is made of and the batch size of the component. The present guideline VDI 3392 Part 2 gives special information of dressing conventional grinding wheels using the abrasives silicon carbide and also fused and sintered corundum. Practical information is given regarding the initial design of a trueing and dressing operation and on maintenance and care of the dressing tool. The guideline is aimed at production engineers and machine operators to help them in designing dressing processes as part of their work planning and preparation activities as well as in trouble-shooting and adapting or optimising existing processes. For information about dressing grinding wheels using superabrasives such as diamond and boron nitride (CBN), see guideline VDI 3392 Part 3.
