Limit speed
Maximum/minimum (spindle) speed: The maximum speed of a spindle may be limited by
values defined in the machine data, the -> PLC or -> setting data.
Linear axis
The linear axis is an axis which, in contrast to a rotary axis, describes a straight line.
Linear interpolation
The tool travels along a straight line to the destination point while machining the workpiece.
Load memory
For the CPU 314 of the -> PLC, the load memory is equal to the -> Work memory .
Look ahead
With the look ahead function, a configurable number of traversing blocks is read in advance
in order to calculate the optimum machining velocity.
Machine
Control operating area
Machine axes
Axes which exist physically on the machine tool.
Machine control panel
An operator panel on a machine tool with operating elements such as keys, rotary switches
etc. and simple indicators such as LEDs. It is used to control the machine tool directly via the
PLC.
Machine coordinate system
System of coordinates based on the axes of the machine tool.
Machine zero
A fixed point on the machine tool, which can be referenced by all (derived) measuring
systems.
