Leadscrew error compensation
Compensation for the mechanical inaccuracies of a leadscrew participating in the feed. The
control uses stored deviation values for the compensation.
Limit speed
Maximum/minimum (spindle) speed: The maximum speed of a spindle can be limited by
specifying machine data, the → PLC or → setting data.
Linear axis
In contrast to a rotary axis, a linear axis describes a straight line.
Linear interpolation
The tool is moved on a straight line to the end point, and the workpiece is thereby machined.
Load memory
The load memory is the same as → RAM for the CPU 314 of the → PLC.
Look Ahead
The Look Ahead function is used to achieve an optimal machining speed by looking ahead
over an assignable number of traversing blocks.
Machine axes
Axes that exist physically in the machine tool.
Machine control panel
Operator panel of the machine tool containing keys, knobs, etc. and simple display elements,
such as LEDs. It is used for immediate control of the machine tool via the PLC.
Machine coordinate system
Coordinate system that is relative to the axes of the machine tool.
Machine fixed-point
Point that is uniquely defined by the machine tool, e.g., machine reference point.
Machine zero
Fixed point of the machine tool to which all (derived) measuring systems can be traced back.
