name the three basic motion types for a machining center
- rapid motion
- circular interpolation
- linear interpolation
in cnc terms ,interpolation means the cnc machine automatically compensates for diameter of a milling cutter?
in cnc terms interpolation means the cnc machine does ist best to provide the intended motion based on a limited amount of program data. cutter radius compensation is used to compensate for cutter size
name three things all motion types have in common
- they are modal
- they require that you program the end point of the motion
- they can be done with absolute or incremental posioning
- they allow you to omit leading zero
a good rule of thumb is to use .1 inch aproach distance when approachin surfaces that are not prone to much variation?
the most important application for linear interpolation is to provide a way to machine straight surfaces
what G code is used to specify rapid motion?
what G code is used to specify linear interpolation?
what G code is used to specify clockwise circular interrpolation?
go2 or g2 is clockwise
g03 g3 is counter clockwise
many machining operations require but one feedrate word per tool?
the preferred positioning method is incremental positioning?
false the preferred method is absolute positioning
the easiest way to specify the arc size in a circular interpolation command is with
- directional vectors
- an r word
- cutter radius compensation
- fixture offsets
an R word is the easiest
which G code is used to specify the xy plane?
which g code is used to specify y z plane
g19 what is this?
with the exception of programming a full circle in one command most machining centers require circular interpolation commands that cross no more than one quadrant line
