Topic overview Dynamic Efficiency Dynamic Precision

TNC 640 – Running of NC programs Dynamic Precision M-NC, 03.2014 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

Cross Talk Compensation (CTC) SV M-NC

CTC – Application Example JK, 09.2013 CTC off CTC on Motion errors Precise TCP motion provides lead to surface defects better surface quality and accuracy

Accuracy of Circular Movement JK, 09.2013 Deviation from the nominal Damage to the stud from milling contour enlarged 500-fold the square

Active Vibration Damping (AVD) SV M-NC

Active Vibration Damping (AVD) – KGM Measurement JK, 09.2013 KGM cross grid measurement, deviation (2000x magnified) 80 80 40 40 y [mm] y [mm] 0 0 -40 -40 AVD off AVD on -80 -80 -80 -40 0 40 80 -80 -40 0 40 80 x [mm] 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

Active Vibration Damping (AVD) - Benefits JK, 09.2013 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

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

Determine the loading weight for LAC M-NC, 10.2014 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:  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 Benefits  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

Determine the loading weight for LAC M-NC, 10.2014

Resume JK, 09.2013 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
