چکیده
The roughness origin of machined surfaces is caused by the following physical causes: copying shape and cutting part tool into workpiece, existence vibration tool, build-up edge (BUE) on edge. current work aims to analyze amplitude tools. was observed hardened steel workpieces. Internal turning technology used, we used several different boring bars (steel; carbide; tuned mass damper—TMD; impact damper—ID) an internal operation using CBN inserts. We revealed tool’s slenderness coefficient (TSC) values for stable operations. For holder, value TSC ? 4.25; carbide 5.5; TMD 4.5 7.75; ID 8. surface’s practically unchanged within limits machining. However, if tools exceed presented limits, parameters deteriorate significantly; example parameter (Ra) deteriorated from 0.350 ?m 1.832 ?m.
