Problem                     Cause                                                                        Remedy
     Cutting edge build up
                             low cutting speed                                                           increase cutting speed
                             excessive honing of cutting lip                                             reduce cutting lip honing
                             bright finish cutting lip                                                   have tool coated

Heavy wear at flank          cutting speed too high                                                      reduce cutting speed
                             feed too low                                                                increase feed
                             clearance angle too small                                                   increase clearance angle

Crumbling on cutting lips    non rigid conditions, insufficient workpiece                                rigid clamping of workpiece
                                                                                                          reduce feed

                             interrupted cut

                             max. wear values exceeded                                                   reduce tool change intervals

                             incorrect tool type                                                         apply suitable tool

Land wear                    non rigid conditions, insufficient workpiece                                rigid clamping of workpiece
                                                                                                          check and correct concentricity if possible
                               clamping

                             deviation from concentricity too large

                             back taper too small                                                        increase back taper

                             incorrect coolant (oil), coolant too weak                                   increase strength of coolant or use neat oil

Scoring on tool body         non rigid conditions, insufficient workpiece                                rigid clamping of workpiece
                                                                                                          check and correct concentricity if possible
                               clamping

                             deviation from concentricity too large

                             interrupted cut                                                             reduce feed

                             abrasive workpiece material                                                 increase strength of coolant or use neat oil
