The cutting of more and more complex parts requires high material removal speed, high surface quality, strict tolerance and reliable machining process, which requires a smarter and higher performance CNC system to meet the requirements.
As a world-class CNC system, German HEIDENHAIN CNC system has rich functions and many software options, which can fully meet the demanding requirements of the industry. Today we will take a look at the powerful 5-axis machining functions of the HEIDENHAIN TNC CNC system.
01
digital twin
Realistic simulation function improves production process reliability
On the programming station, the digital twin provides an accurate digital version of the machine tool model, which can make full use of the actual kinematic characteristics, machine parameters and functions of the machine tool in the front-end design and programming. Users can safely use the programming station and the program output by CAM, and run the NC program smoothly in actual processing.
Quickly and reliably produce:
1) Check and optimize the tool path;
2) Avoid program interruption;
3) avoid collision;
4) Make full use of the processing area;
5) Test complex 5-axis motion;
6) Check and optimize the workpiece clamping position.
02
DCM
Dynamic Collision Monitoring
Five-axis machining motions are complex and almost impossible to predict. To minimize machine tool accidents and machine operator injuries, Dynamic Collision Monitoring (DCM) monitors the entire machining area to avoid collisions between tools, fixtures and machine components. In test run mode, collisions are detected even before the program runs, thus avoiding program interruptions and re-clamping.
Maximum machine protection:
1) Realistically display machine tool components;
2) Reliable retract distance;
3) Intuitive graphic display and auxiliary dialog prompts;
4) Monitor the knives, knives and fixtures;
5) Make full use of the processing area.
03
KinematicsOpt
Fully automatic cycle effectively improves 5-axis accuracy
The KinematicsOpt function checks the accuracy of a rotary or swivel axis and compensates for offsets in its center of rotation. The offset values are automatically sent to the kinematics model and taken into account there.
Long-term maintenance of high-precision processing:
1) Easy to perform secondary calibration and maintain high precision for a long time;
2) Data backup to deal with changes in the motion characteristic model;
3) Easily restore the determined configuration;
4) Measurement log function to meet strict documentation requirements.
04
OCM
Efficient machining and reduced tool wear
The "Excellent Contour Milling" cycle efficiently and tool-friendly roughs and finishes pockets and spigots of any shape. The CNC system automatically calculates complex cycloidal milling movements, and the built-in cutting parameter calculator is convenient and easy to use to determine the ideal processing parameters.
Effective and reliable, OCM is a shortcut to increase production:
1) Consistent cutting conditions;
2) Higher cutting parameters;
3) Excellent chip removal performance;
4) Reduce tool heating;
5) Significantly reduce tool wear;
6) The time is shorter and the cutting volume is larger.

5 axis machining
Powerful functions to meet demanding processing requirements
During 5-axis machining, the linear axes often perform highly dynamic compensating movements. Therefore, the requirement for high feed rates and high accelerations can lead to vibration or other sources of error. The powerful motion control function of TNC can effectively optimize the compensation motion of each linear axis, providing an ideal solution for reducing vibration and achieving high dynamic performance in cutting.
The TNC control system ensures smooth and high-precision movement of the rotary axes to achieve ideal surface quality during rapid direction changes between tool and workpiece.
Functions for high precision and high dynamics in tool movement:
1) Dynamic high precision: improve the precision of the axis in high dynamic motion;
2) TCPM: Simple and practical setting, meeting the requirements of each independent workpiece and processing;
3) Cycle 32: Achieve high surface quality, shorten machining time and meet tight tolerance requirements.

Loop 444
Automatable quality assurance on the machine
Cycle 444 processes measuring point data for 3D geometries to ensure high quality. Simply enter a given survey point with its coordinates and normal vector. The TNC automatically performs probing and determines whether the measured point is within tolerance.
Measure contour error in 3D space:
1) Fully automatic process optimization;
2) The tilted probe measures 3D geometry;
3) 3D calibration function can measure with high precision;
4) Use system parameters to query under program control;
5) Detect necessary repair processing;
6) Report program interruption and error information;
7) Measurement logs in HTML format, easy to read.
