CNC Programming Circular Interpolation

Definisi G02, G03, I, J & K
  • G02: Circular interpolation (CW)
  • G03: Circular interpolation (CCW)
  • I, J & K (Use when <=360 degree) " Incremental distance from SP to CP of arc "
  • I: Specifies the incremental ±X distance from the center of the tool at the start of the arc to the center of the arc.
  • J: Specifies the incremental ±Y distance from the center of tool at the start of the arc to the center of the arc

Circular interpolation
why R?

•R is easier to define, easier to make a mistake and get an incorrect radius.
•With R, the machine still do the work whether the R is correct or incorrect.
•With incorrect I, J & K, the machine will stop and gives an error message before executing.
•With R, to generate a circle path of over 180 degrees, then specify a negative R.

I need help creating the program codes to produce a R12.7 internal arc into a R19.05 external arc with a 1" endmill?
