FAQ
Q Siemens 840D vs Heidenhain TNC?
A
840D: modular, CNC+PLC+safety integrated, deep SINAMICS servo coupling. Heidenhain: high-end grinding/milling, conversational programming, preferred in mold/die shops.
Q What is 5-axis RTCP?
A
Rotation Tool Center Point — tool-tip tracking. When A/C axes rotate, the CNC compensates tool-center position; CAM doesn't need to know machine kinematics.
Q CNC cloud updates?
A
Siemens MindSphere, Heidenhain Connected Machining, Fanuc FIELD — cloud connectivity, remote diagnostics, version management and machine-data collection.
