SUMMARY
The discussion centers on calculating the torque required to generate at least 1.5 psi in a syringe using a lead screw in a CNC machine setup. The user is constructing a syringe mechanism with one-way valves and has determined that the axial torque needed is approximately 0.184 kg*cm using a square lead screw for efficiency. Accurate results depend on knowing friction values for both the lead screw and the plunger, which can be obtained experimentally. The user plans to utilize a stepper motor controlled by an Arduino for precise fluid displacement.
