Table of Contents

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.

Functionality

The path-jerk limitation can be activated/deactivated by programming the setting data.

● Value range: TRUE, FALSE

Application:

● Part program

● Static synchronized action

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 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 is used to write NC programs, → synchronized actions, and → cycles.

It provides: control structures → user-defined variables, → system variables, → macro

programming.
