Frame
A frame is an arithmetic rule that transforms one Cartesian coordinate system into another
Cartesian coordinate system. A frame contains the following components: → zero offset,
→ rotation, → scaling, → mirroring.
Geometry
Description of a → workpiece in the → workpiece coordinate system.
Geometry axis
The geometry axes form the 2 or 3-dimensional → workpiece coordinate system in which, in
→ part programs, the geometry of the workpiece is programmed.
Ground
Ground is taken as the total of all linked inactive parts of a device which will not become live
with a dangerous contact voltage even in the event of a malfunction.
Helical interpolation
The helical interpolation function is ideal for machining internal and external threads using
form milling cutters and for milling lubrication grooves.
The helix comprises two motions:
● Circular motion in one plane
● A linear motion perpendicular to this plane
High-level CNC language
The high-level language offers: → user-defined variables, → system variables, → macro
techniques.
High-speed digital inputs/outputs
The digital inputs can be used for example to start fast CNC program routines (interrupt
routines). High-speed, program-driven switching functions can be initiated via the digital
CNC outputs
