1. INTRODUCTION
A fixturing device is a parts assembly with very precise technical functions which aims to machine by drilling parts from machine building industry which are made of different materials and having specific characteristics.
The use of a fixture device allows an uniformity of the machining, a reduced machining time and machine operator safety [1], [2].
The shafts are parts with cylindrical shape used mainly in machine building industry.
They are supported by knuckles (prisms) and used for supporting the rotation parts (bell wheels, toothed wheels, clutches etc.). The shafts are also stressed to bending, their main purpose is to transmit the torque [3].
By meaning, a software is an intellectual product which consists in programs, procedures, rules and associated documentation used for the functionality of a data processing system [4].
In the last time, numerous software application as Aut°CAD [5], Autodesk Inventor [6,7], CATIA, were developed in order to carry out 2D and 3D modeling of some components.
These software were used to design, visualize and simulate the products before manufacturing stage.
The drilling fixture and the straight shaft presented in this paper were drawn using Autodesk Inventor software package, which satisfies all aspects related to design, esthetics and assemblage.
The orientation and fixing scheme, as far as the orientation elements of the fixture device were drawn using Aut°CAD designing software, which enables with efficiency accurate 2D modeling of component parts.
2. THE ORIENTATION SCHEMA OF THE PART
The position of the future machined surface is determined in the system of the orienting. This system consists in orientation elements which come in contact with orientation surfaces of the blank [8].
The orientation bases system can be chosen in many options, meaning that the orientation bases can be the same with elevation bases or not, or an orientation...
