Flashcards in advanced linear and circular interpolation 150401b Deck (16):
1

name the three basic motion types for a machining center

  1. rapid motion 
  2. circular interpolation
  3. linear interpolation

2

in cnc terms ,interpolation means the cnc machine automatically compensates for diameter of a milling cutter?

  • true
  • false

false

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

3

name three things all motion types have in common

  1. they are modal
  2. they require that you program the end point of the motion
  3. they can be done with absolute or incremental posioning
  4. they allow you to omit leading zero

4

a good rule of thumb is to use .1 inch aproach distance when approachin surfaces that are not prone to much variation?

  • true 
  • false

true

5

the most important application for linear interpolation is to provide a way to machine straight surfaces

  • true 
  • false

true

6

what G code is used to specify rapid motion?

G00

7

what G code is used to specify linear interpolation?

G01    G1

8

what G code is used to specify clockwise circular  interrpolation?

go2 or g2 is clockwise

g03 g3 is counter clockwise

9

many machining operations require but one feedrate word per tool?

  • true
  • false

true

10

the preferred positioning method is incremental positioning?

  • true
  • false

false the preferred method is absolute positioning

11

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

12

which G code is used to specify the xy plane?

g17

13

which g code is used to specify y z plane

g18

14

g19 what is this?

zy plane

15

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

  • true
  • false

true
