7.1.2. Drilling data interpreter
Various drilling
data formats
The drilling data interpreter recognizes data in the following
standards Excellon, Sieb&Maier1000 and Sieb&Maier3000.
A drilling file always starts with one or two percent signs and ends
with the command M30. In between, there can be any number of
lines with X and Y coordinates and the tool number.
Drilling data
sntax
The syntax is as follows:
% oder %%
[Xval][Yval][Tx]
.....
M30
There are two different formats. In format 1, the coordinate values
are always 5-digit numbers, although it is possible to leave off the
trailing zeros (e.g. X021 corresponds to 2100).
In format 2, leading zeros are discarded and the coordinate values
therefore comprise different numbers of digits.
The drilling formats prescribe the following syntactical rules,
amongst others, which must be observed when creating or revising
the data.
Every command must be in its own line
If coordinates and a tool command are contained in the same line,
then the tool is changed first before drilling takes place at the
position
The coordinates can also include a decimal point, e.g. X123.456
All lines before the percent sign(s) are regarded as remarks and
are skipped
