Contour Definition Programming And Addition Of Chamfers Or Radiuses - Siemens SINUMERIK 808D Programming And Operating Manual

4.2.1.5

Contour definition programming and addition of chamfers or radiuses

Chamfers or radiuses can be added after each traversing block between linear and circular contours. For example, to grind
sharp edges of workpieces.
The following combinations are possible during addition:
● between two straight lines
● between two circular arcs
● between a circular arc and a straight line
● between a straight line and a circular arc
Format
, C...; Chamfer
, R...; Rounding
Example
N10 G1 X10. Y100. F1000 G17
N20, A140, C7.5
N30 X80. Y70., A95.824, R10
Three straight lines:
ISO dialect mode
In the ISO dialect original, the address C can be used as axis name as well as for denoting a chamfer on the contour.
The address R can either be a cycle parameter or an identifier of the radius of a contour.
The address A is the angle in contour definition.
To differentiate between these two possibilities, a comma "," must be used while programming the contour definition before
the address "A", "R" or "C".
Siemens mode
The identifiers of chamfer and radius are defined in Siemens mode using the machine data. Name conflicts can be avoided
this way. There should be no comma before the identifier of the radius or chamfer.
