Description 1.4 Coordinate systems Coordinate systems As a rule, a coordinate system is formed from three mutually perpendicular coordinate axes. The positive directions of the coordinate axes are defined using the so-called "3-finger rule" of the right hand. The coordinate system is related to the workpiece and programming takes place independently of whether the tool or the workpiece is being traversed.
Description 1.4 Coordinate systems The origin of this coordinate system is the machine zero. This point is only a reference point which is defined by the machine manufacturer. It does not have to be approachable. The traversing range of the machine axes can by in the negative range. Workpiece coordinate system (WCS) To describe the geometry of a workpiece in the workpiece program, a right-handed, right- angled coordinate system is also used.
Description 1.4 Coordinate systems Figure 1-5 Workpiece on the machine Current workpiece coordinate system The programmed work offset TRANS can be used to generate an offset with reference to the workpiece coordinate system resulting in the current workpiece coordinate system resulting in the current workpiece coordinate system (see Section "Programmable work offset: TRANS").

Programming 3.2 Positional data Positional data 3.2.1 Program dimensions In this section you will find descriptions of the commands, with which you can directly pro- gram dimensions taken from a drawing. This has the advantage that no extensive calcula- tions have to be made for NC programming. Note The commands described in this section stand in most cases at the start of a NC program.

Programming 3.2 Positional data nate system). This is dependent on which offsets are currently active: programmable, settable, or no offsets. Upon program start, G90 is active for all axes and remains active until it is deselected in a subsequent block by G91 (incremental dimensioning data) (modally active). Incremental dimensioning G91 With incremental dimensioning, the numerical value of the path information corresponds to the axis path to be traversed.

Programming 3.2 Positional data 3.2.7 Programmable mirroring (MIRROR, AMIRROR) Function MIRROR/AMIRROR can be used to mirror workpiece shapes on coordinate axes. All trav- ersing movements, which are programmed after the mirror call, e.g., in the subprogram, are executed in the mirror image. Programming MIRROR X0 Y0 Z0 (substituting instruction programmed in a separate NC block) AMIRROR X0 Y0 Z0 (additive instruction programmed in a separate NC block)

Programming 3.2 Positional data The same applies to the direction of circle rotation (G2/G3 or G3/G2). Note If you program an additive rotation with AROT after MIRROR, you may have to work with reversed directions of rotation (positive/negative or negative/positive). Mirrors on the geome- try axes are converted automatically by the control into rotations and, where appropriate, mirrors on the mirror axis specified in the machine data.
Programming 3.2 Positional data 3.2.8 Settable work offset: G54 to G59, G507 to G512, G500, G53, G153 Functionality The settable work offset specifies the position of the workpiece zero point on the machine (offset of the workpiece zero point with respect to the machine zero point). This offset is de- termined upon clamping of the workpiece into the machine and must be entered in the corre- sponding data field by the operator.

In some cases, different axis identifiers are configured for MD 20080 and for the geometry axis identifiers MD 20060: AXCONF_GEOAX_NAME_TAB.
