cnc milling programing
- G CODES -
- G85
- (BORING).
- A G85 (Boring) command is written in the following
- format:
- please refer to page 52 for the variable definitions.
- (G9Ø) (G98)
- or or
- (G91) (G99)
- G85 X.... Y.... Z.... R.... F.... ;
- + Z AXIS DIRECTION.
- Sequence of moves:
- Op 1) Rapid position to X, Y and Z (the initial level).
- Op 2) Rapid traverse to R point level.
- Op 3) Feed in to the Z depth.
- Op 4) Feed back to R point level.
- If the G98 code is programmed within the cycle, the
- next move will be a rapid traverse to the Initial level. If
- the G99 code is programmed within the cycle, there
- will be no movement.
