Mold&Die commands
3.1 List of G Codes
The following G Codes are relevant for Mold&Die
• G Code Group4 : FIFO
STARTFIFO / STOPFIFO / FIFOCTRL
Recommended function : FIFOCTRL
Preprocessing memory control - Avoids that the FIFO buffer runs empty
• G Code Group10 : EXACT STOP - CONTINUOUS PATH MODE
LOOK AHEAD
G60 / G64 / G641 / G642
Recommended function : G642
Use of LOOK AHEAD:
The purpose of continuous-path control is to increase speed and harmonize
traversing performance. In path cont
rol function this is achieved with two
functions.
Look ahead - Look ahead speed control :
The control
system calculates several NC blocks ahead and determines a
modal speed profile. Th
e way in which this speed control is calculated can be
set with functions G64 or G642.
Recommended function : Corner rounding G642
The look ahead function also means that the control system is able to round
the corners it detects. Th
e programmed corner points are therefore not appro-
ached exactly. Sharp corners are rounded.
Insertion of
Circle or Spline elements.
Corner Rounding G642
