1. - The part shown in the Figure has been rough turned. Write a word address program segment using TNR compensation to perform the finish pass (facing and turning). Assume the person has entered the following information into the offset file: Tool offset values for tool edge programming TNR value Tool nose vector 3 TNR comp is canceled (G40)| Notes: Path of the cutter center Programmed path TNR comp right (G42) is in effect. Point (imaginary tool nose radius) used to position the tool with TNR compensation canceled (G40) 1. Use 3" dia. bar stock x 3.5" long and faced. 2. Machine at constants surface speed of 200 sfpm. 3. Limit the rotation of the spindle to 3000 rpm when G96 is in effect. 4. Set the feed rate for facing at .005 ipr. 5. Set the feed rate for turning at .007 ipr. 6. Use tool 1 with offset 1. 7. Use front turret lathe programming mode.
