ENGR3190U: Manufacturing and Production Processes Lecture 12 Circular Interpolation – in class exercises R-method (G02 or G03) (End Point: X,Y) (radius: R or R- ) (Feed Rate: F) If cut 0 < arc ≤ 180 o use R, eg. R3.0 If cut 180 < arc ≤ 360 o use R-, eg. R-3.0 Example Write the statement to cut the following arc. Use absolute programming. Start point = X2.0 Y4.0, Centre point = X2.0 Y1.0, End point = X2.0 Y-2.0 N10 G90 G02 Y-2.0 R3.0 F3.0 (not need to repeat X2.0 because it is unchanged) I ,J,K – method (G02 or G03) (End Point: X,Y) (Modifiers: I, J) (Feed Rate: F) I = incremental distance from the start of arc to centre of arc in “X” J = incremental distance from the start of arc to centre of arc in “Y” When I or J =0, you can leave it out.

Unformatted text preview: Write the statement to cut the arc in example 1 using I,J method. Use absolute programming. N10 G90 G02 Y-2.0 J-3.0 F3.0 (not need to put I0) Example 2 Write the statement to cut the following arc using both R-method and I,J method. Use absolute programming. 1 Example 3 Write the statement to cut the following arc using both R-method and I,J method. Use absolute programming. Example 4 Write the statement to cut the following arc using both R-method and I,J method. Use absolute programming. Tool is ½” mill. Example 5 (on past year’s quiz) Write the statement to cut the following arc using both R-method and I,J method. Tool is ½” end mill. Use incremental programming. 2...
