9. Fig 9 G23 thread cutting Generally repeat the thread cutting many times in the same path from the roughing to the finish turning when the thread is machined The thread cutting starts after receiving 1 turn signal from the spindle encoder and so the cutting points on the circle of machining workpiece are the same when repeating the thread cutting many times the spindle speed must not be changed at the same time otherwise there is the error of thread cutting The feedrate of thread cutting and the spindle speed are comfortable If the spindle speed is high the system will not respond timely which cause the thread to be damaged The recommended spindle speed is as follows N x P 3000 N spindle speed Unit r min Max speed is less than 2000 r min P thread lead Unit mm Inch thread value must be converted to the metric one There is wrong screw lead caused by the acceleration deceleration when the thread cutting is started and ended To avoid the above mentioned problem the thread length defined is longer than the actual requirement Generally the length is more than 1 3 mm when the thread is cut with the acceleration 50 fh A 1 Fig 10 Thread cutting 105 GSK928TE GSK928TC CNC System User Manual 5 Example thread lead 2 mm cutting depth 2 5 mm diameter value cutting twice as Fig 10 N0000 N0010 N0020 N0030 N0040 N0050 N0060 N0070 N0080 Note 1 Note 2 In the course of thread cutt
