Title:

DEVELOPMENT OF A MANAGER SYSTEM FOR CALCULATION OF MACHINE ELEMENTS FOR MECHANICAL DESIGN

Summary :

WITH A MARKET MORE AND MORE DEMANDING IN TERMS OF EFFICIENCY AND COSTS, ONE HAS THE NEED TO INTEGRATED ALL THE POSSIBLE INFORMATION OF A COMPANY, HELPING IN THIS WAY TO GUARANTEE THE QUALITY OF PRODUCTS AND SERVICES. MOREOVER, NOWADAYS THERE ARE PLENTY OF RESOURCES TO SYSTEMATIZE THE REPETITIVE AND TEDIOUS TASKS, SUCH AS CALCULATING A SHAFT OR A PAIR OF GEARS. BY USING THEM, THE ENGINEER WILL HOLD ALL THE DATA HE/SHE NEEDS AND, AT THE SAME TIME, WILL HAVE MORE AVAILABLE TIME FOR MORE CREATIVE TASKS. WITH THIS FOCUS, THIS WORK PRESENTS THE DEVELOPMENT OF A MANAGER SYSTEM FOR CALCULATIONS OF MACHINE ELEMENTS FOR MECHANICAL PROJECTS. IT WAS DEVISED UNDER THE CONTEXT OF EDM-ENGINEERING DATA MANAGEMENT. THE SYSTEM IS CONSTITUTED OF A MANAGER PROGRAM, A DATABASE AND MODULES OF CALCULATION OF MACHINE ELEMENTS. THE MANAGER PROGRAM CONTROLS THE FLOW OF CALCULATIONS IN THE PROJECT THROUGH EXISTENCE AND CONSISTENCY RULES AMONG THE MECHANICAL ELEMENTS, AND ALSO PROVIDES THE AVAILABILITY OF THE INPUT AND OUTPUT DATA. THOSE RULES ARE FIRED THROUGH CONSULTATIONS TO THE DATA STORED INTO A RELATIONAL DATABASE. AS CONSISTENCY RULE ONE CAN CITE, FOR EXAMPLE, THE ONE STATING THAT THE LUBRICANT USED IN THE GEARS CALCULATION BE THE SAME AS THAT USED IN THE CALCULATION OF THE BEARINGS. THE DATABASE WAS DESIGNED BY USING A LOGICAL MODEL BASED ON ME-R, TAYLORED TO THE ASSEMBLY OF A SPECIFIC MECHANICAL SYSTEM : A GEARBOX. THE CALCULATIONS ARE PERFORMED BY INDEPENDENT COMPUTATIONAL MODULES WHICH USE TRADITIONAL METHODS OF ELEMENTS OF MACHINES CALCULATION (NIEMANN, 1971). KEYWORDS: PDM; MACHINE ELEMENTS; INTEGRATION.
