12 Topic overview Dynamic Efficiency Dynamic Precision

13 TNC 640 Running of NC programs Dynamic Precision M-NC, Dynamic Precision High production rates of precisely machined workpieces CTC (Cross Talk Compensation) prevents errors caused by acceleration forces. AVD (Active Vibration Damping) reduces machine vibrations PAC (Position Adaptive Control) always offers the optimum controller setting irrespective of the position in the working space LAC (Load Adaptive Control) permits adjusting the controller settings depending on the workpiece weight

14 Cross Talk Compensation (CTC) SV M-NC

15 CTC Application Example JK, CTC off Motion errors lead to surface defects CTC on Precise TCP motion provides better surface quality and accuracy

16 Accuracy of Circular Movement JK, Deviation from the nominal contour enlarged 500-fold Damage to the stud from milling the square

17 Active Vibration Damping (AVD) SV M-NC

18 Active Vibration Damping (AVD) KGM Measurement JK, KGM cross grid measurement, deviation (2000x magnified) y [mm] 0 y [mm] AVD off x [mm] AVD on x [mm] 5-axis vertical machining centre Oscillation at 17 Hz caused by foundation TCP position error AVD off:15 µm AVD on: 4 µm

19 Active Vibration Damping (AVD) - Benefits JK, AVD off AVD on The adaptive control function AVD can significantly reduce the level of machine vibration Fast and oscillation free movements Enhanced surface quality Optimized machining time

20 Dynamic Precision in Dental Technology SV M-NC Series production of single parts with Dynamic Precision Increase in productivity using the example of an 8-element bridge (7 %) Shorter processing time Better surface Higher workpiece accuracy

21 Determine the loading weight for LAC M-NC, Cycle 239 determines the loading weight for a quick adaption of LAC (Option 143) LAC optimize feed forward and controller parameter dependent on the loading weight continuously Cycle 239: Benefits Reset parameters to enable safe controlling of critical axes independently on the loading weight Determines the loading weight and adapt LAC for a volatile variation of it Very easy to use for the operator OEM configures the cycle process No adaption in the PLC is necessary TNC availiability TNC 620 / TNC 640

22 Determine the loading weight for LAC M-NC,

23 Resume JK, The HEIDENHAIN solution for high production rates of precisely machined workpieces increases accuracy during dynamic contouring movements reduces scrap and rework saves time and costs
