Leadscrew error
compensation
Compensation of mechanical inaccuracies in a leadscrew involved
in the feed motion. Errors are compensated by the control based on
stored deviation measurements.
Limit speed Minimum/maximum (spindle) speed: The maximum speed of a
spindle can 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.
Look Ahead The Look Ahead function is a means of optimizing the machining
velocity by looking ahead over a parameterizable number of
traversing blocks.
Look Ahead for
contour violations
The control detects and reports the following types of collision:
1. Path is shorter than tool radius.
2. Width of inside corner is less than the tool diameter.
M
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 for direct control of the machine tool via the PLC.
