Designed for use with its grinding machines, Holroyd Precison's Holroyd Profile Management System (HPMS) is an optional desktop suite of software for helical component design and management. The suite consists of a family of subprograms that enable the manipulation and analysis of profiles. The subprograms include Editor for profile modification; Cutter, which calculates the shape of the grinding wheel or cutter blades for the Cutter Sharpener; Clearance, which simulates clearances for rotor repairs; and Update, which calculates a mean profile from coordinate measuring machine scan files or Thread Grinder in-process scans, enabling modification of the transverse rotor profile. The subprograms are compatible with a variety of file types and also include a variety of other functions.

Subject to design conditions, the software enables direct editing of the gap between the male and female rotors to enhance machinability. Beginning with a text file defining a single flute on a male or female rotor or a screw in the transverse or axial plane, the system checks that the profile complies with machinability requirements, and then enables file manipulation to correct any problems. When a file is imported, the software displays the resultant profile with information relating to the points, such as X, Y and angle coordinates, which can then be marked and edited as needed. Information related to measurement probes and tool offsets is also displayed. During the production cycle, the software can also be used to modify the shape of the grinding wheel or milling tool based on actual profile measurements for profile quality.
