1.5.3 Detail of Contour Calculation
This chapter explains the details of contour calculations, such as those
for cross points or tangential points, that are supported by contour
programming.
A figure or part of a contour for which an end point has not yet been
determined is said to be in the pending state. A pending figure is
indicated by a dotted line.
On the screen for entering contour figure data, more data input items
than required will appear. These data items are used to calculate the
cross points with the immediately preceding pending figure block, and
also to calculate the end point.
Ten successive figure blocks can be specified as pending blocks.
1.5.3.1 Line
(1) When the preceding figure is not pending
(a) Only X is inputted
-> This line is determined as a vertical line.
(b) Only Z is inputted
-> This line is determined as a horizontal line.
(c) A and either X or Z are inputted
-> The end point that is not inputted is calculated.
(2) When the preceding figure specifying an arc is not pending, and
"TOUCH LAST" is specified in the line.
(a) Either X or Z is inputted
-> The angle A is calculated automatically, and an end
point is determined.
If neither X nor Z is inputted, this line will be pending.
