W4: Grinding-specific tool offset and tool monitoring17.2 Online tool offsetExtended FunctionsFunction Manual, 03/2013, 6FC5397-1BP40-3BA1 817General informationAn online tool offset can be activated for every grinding tool in any channel.The online tool offset is generally applied as a length compensation. Like geometry and weardata, lengths are assigned to geometry axes on the basis of the current plane as a functionof the tool type.The grinding spindle monitoring function remains active when an online tool offset isselected.NoteThe offset always corrects the wear parameters of the selected length. If the lengthcompensation is identical for several cutting edges, then a chaining specification must beused to ensure that the values for the 2nd cutting edge are automatically corrected as well.If online offsets are active in the machining channel, then the wear values for the active toolin this channel may not be changed from the machining program or via operator inputs.Modifications to the radius wear (P15) are not taken into account until the tool is reselected.The online offset is also applied to the constant grinding wheel peripheral speed (GWPS),i.e. the spindle speed is corrected by the corresponding value.InstructionsThe following commands are provided for online tool offsets:Command MeaningFCTDEF, , , ,, , )Parameterize function(up to 3rd degree polynomial)(Fine Tool Offset Definition)PUTFTOCF(, , , no.>, )Write online tool offsetcontinuously(Put Fine Tool Offset Compensation)PUTFTOC(, , , )Write online tool offsetdiscretely(Put Fine Tool Offset Compensation)FTOCON Activation of online tool offset(Fine Tool Offset Compensation ON)FTOCOF Deactivation of online tool offset(Fine Tool Offset Compensation OFF)NoteChanges to the correction values in the TOA memory do not take effect until T or D isprogrammed again.References:Programming Manual, Job Planning
