Teach In is a means of creating or correcting part programs. The
individual program blocks can be input via the keyboard and
executed immediately. Positions approached via the direction keys
or handwheel can also be stored. Additional information such as G
functions, feedrates or M functions can be entered in the same
block.

A tool employed to shape the workpiece, for example, a turning tool,
milling cutter, drill, laser beam, grinding wheel, etc.
A contour is programmed on the assumption that a pointed tool will
be used. Since this is not always the case in practice, the curvature
radius of the tool being used is specified so that the control can
make allowance for it. The curvature centre point is guided
equidistantly to the contour at an offset corresponding to the
curvature radius.
A tool is selected by programming a T function (5 decades, integer)
in the block. Up to nine tool edges (D addresses) can be assigned
to each T number. The number of tools to be managed in the control
is set in parameterization.
Tool length compensation is selected by programming D numbers.
In order to program a desired --> workpiece contour directly, the
control must traverse a path equidistant to the programmed contour,
taking into account the radius of the tool used (G41/G42).
(G41/G42).
Programming in a Cartesian coordinate system, execution in a
non--Cartesian coordinate system (e.g. with machine axes as rotary
axes).
Employed in conjunction with Transmit, Inclined Axis, 5--Axis
