      </table><br><p class="para_topic">The Machining Data library stores machining parameters for reuse. It sets the speed, feeds, depth of cut, and stepover values based on the current cutting conditions. The Machining Data library improves on the Feeds and Speeds library (which only sets the speed and feed values) for milling. To efficiently cut similar parts, determine the optimum parameter settings for your cutting conditions, and add them to the Machining Data Library. Any user can then apply these settings to his/her operations. The library uses three primary inputs from the operation: Tool Material, Part Material, and Cut Method. The secondary inputs are Tool Diameter and Tool Length.</p>
