only one command is required to machine a hole if it is programmed with a canned cycle?
once you program the firts hole with a canned cycle you can simply list hole locations to machine others
after the last hole is machined you must remember to cancel the canned cylce mode?
what code is used to specify counter boring cycle
what g code is used to specify a standard drilling cycle?
what gcode is used to specify a chip breaking peck drilling cycle?
what g code is used to specify a deep hole peck drilling cycle?
what code is used to specify a tapping cycle?
name two things all hole machining canned cycles share in common?
- all hole machining canned cycles are modal
- all hole machining canned cycles cause four predetermined activities. they rapid to the hole location in x and y,rapid to the r plane machine the hole and retract from the hole
all machining cenetrs require the use of tension/compression tap holders for tapping operations?
machining centers equipped with rigid tapping donot require tension/comprssion tap holders
if you are using theg 76 fine boring cycle and you know the boring bar tip is pointing in the y positive direction when the spindle is at its orient position which of the following words do you include in the g76 command to caue the boring bar to move in the appropriate direction at the hole bottom?
DEFINE the two planes. the R plane and the initial plane, that you use to avoid obstructions when using hole machining canned cycles
- R PLANE this is the position usually right above the work surface
- INITIAL PLANE this is the last z positon prior to the canned cycle command
what g code is used to specify a retract to the initial plane
- g 90
- g 91
- g 98
- g 99
hole machining canned cycles cannot be used with incremental positioning
false they can be and sometimes are helpful
