16 Automatic Geometric Calculations
16.1 Programming Chamfer and Corner Round
The control is able to insert chamfer or rounding between two blocks containing linear (G01) or
circle interpolation (G02, G03) automatically.
A chamfer, the length of which
equals to the value specified at
address
,C
(comma and C) is inserted
between the end point of the block
containing address ,C and the start
point of the forthcoming block.
E.g.:
N1 G1 G91 X30 ,C10
N2 X10 Y40
The value specified at the address
,C shows the distance between the start/end point of chamfer and the supposed intersection of the
two successive blocks. A chamfer may also be inserted between circles or between a circle and a
straight line. In this case value ,C is the length of the chord drawn from intersection.
A rounding, the radius of which
corresponds to the value given at
address
,R
(comma and R) is inserted
between the end point of the block
containing address ,R and the start
point of the forthcoming block.
E.g.:
N1 G91 G01 X30 ,R8
N2 G03 X-30 Y30 R30
A ,R-radius arc is inserted between the two blocks so that the circle osculates to both path
elements.
