Tool Use Time is Down: Tool Use Time is Down:
  • If torque is less than 19.95 Nm then the machine is likely to have Low tool use time.
  • If air temperature is greater than 303.25 K then the machine is likely to have Low tool use time.
  • If torque is less than 16.9 Nm then the machine is likely to have Low tool use time.
  • If rotational speed is less than 1530 rpm then the machine is likely to have Low tool use time.
  • If torque is less than 16.9 Nm then the machine is likely to have Low tool use time.
  • If process temperature is greater than 369.9 K then the machine is likely to have Low tool use time.
Tool Use Time is Up: Tool Use Time is Up:
  • If torque is less than 19.95 Nm then the machine is likely to have High tool use time.
  • If air temperature is less than 303.25 K then the machine is likely to have High tool use time.
  • If the machine that has 50% or more probability of having a tool wear failure then the machine is likely to have High tool use time.
  • If torque is greater than 65.1 Nm then the machine is likely to have High tool use time.
  • If air temperature is less than 381.14 K then the machine is likely to have High tool use time.
  • If the machine that has 60% or more probability of having a overstrain failure then the machine is likely to have High tool use time.
