and point machining
Press the CONTOUR FORMULA soft key. The TNC
then displays the following soft keys:
Soft key Mathematical function
cut with
e.g. QC10 = QC1 & QC5
joined with
e.g. QC25 = QC7 | QC18
joined with, but without cut
e.g. QC12 = QC5 ^ QC25
without
e.g. QC25 = QC1 \ QC2
Parenthesis open
e.g. QC12 = QC1 * (QC2 + QC3)
Parenthesis closed
e.g. QC12 = QC1 * (QC2 + QC3)
Define single contour
e.g. QC12 = QC1
