Independent parameters (variables): • We can change directly in the cutting process • Cutting conditions, such as speed, feed and depth of cut. • Tool material and its condition. • Tool shape, surface finish, and sharpness. • Workpiece material, condition, and temperature. • Cutting fluid. • Machine characteristics (Size, Stiffness, Damping, ….) • Dependent parameters (variables): • Type of chip produced. • Force and energy dissipated in the cutting process. • Temperature rise in the workpiece, the chip, and the tool. • Wear and failure of the tool. • The surface finish produced on the workpiece after machining.","styleRuns":[{"startIndex":0,"length":599,"styleRunExtensions":{"styleRunColorMapExtension":{"colorMap":[{"key":"USER_INTERFACE_THEME_DARK","value":4294967295},{"key":"USER_INTERFACE_THEME_LIGHT","value":4279440147}]}},"fontFamilyName":"Roboto"}]},"headerRuns":[{"startIndex":0,"length":599,"headerMapping":"ATTRIBUTED_STRING_HEADER_MAPPING_UNSPECIFIED"}]}},{"itemSectionRenderer":{"contents":[{"continuationItemRenderer":{"trigger":"CONTINUATION_TRIGGER_ON_ITEM_SHOWN","continuationEndpoint":{"clickTrackingParams":"CMIBELsvGAIiEwjYmY7Np86LAxV-0UIFHfQJCMA=","commandMetadata":{"webCommandMetadata":{"sendPost":true,"apiUrl":"/youtubei/v1/next"}},"continuationCommand":{"token":"Eg0SC1J2MVRkdVIwU3NvGAYyJSIRIgtSdjFUZHVSMFNzbzAAeAJCEGNvbW1lbnRzLXNlY3Rpb24%3D","request":"CONTINUATION_REQUEST_TYPE_WATCH_NEXT"}}}}],"trackingParams":"CMIBELsvGAIiEwjYmY7Np86LAxV-0UIFHfQJCMA=","sectionIdentifier":"comment-item-section","targetId":"comments-section"}}],"trackingParams":"CMEBELovIhMI2JmOzafOiwMVftFCBR30CQjA"}},"secondaryResults":{"secondaryResults":{"results":[{"compactVideoRenderer":{"videoId":"t7QeEQxE2NE","thumbnail":{"thumbnails":[{"url":"https://i.ytimg.com/vi/t7QeEQxE2NE/hqdefault.jpg?sqp=-oaymwEbCKgBEF5IVfKriqkDDggBFQAAiEIYAXABwAEG
