Should You Increase RPM or the Lead of Your Lead Screw?

When it comes to lead screw performance, it's all about axial load and rotational speed (RPM). As you likely know, the relationship between these two factors is known as "pressure velocity", or the PV curve. Simply put, this PV curve defines the safe limits of load and speed.
