Project title: TIGHTENING SUPPLY
INTRODUCTION
During our second year of a license in mechanical engineering, we had to work in a group
of 7 people on a design project for a clamping vice. First of all, in this report, we will present the
objectives of this project, the list of materials and machines that we had used, the range of
machining that we had established to facilitate our work, as well as the difficulties encountered.
I. Objectives of the practical work report
The aim of this project is to enable us to put into practice what we have been taught during
the course about manufacturing techniques, dimensioning and the use of different machines and
tools. This will enable us to make the link between theory and practice.
II. List of equipment and machinery used
• Drill
• Electric saw
• Grinding wheel
• Clamping vice
• Vernier caliper
• Square
• Meter
• Welding unit
• Tapping tools

Materials used
• Angle bracket (255mm)
• Flat iron bar (234mm)
• Rod (180mm)
III. Hypothesis
To enable us to carry out our work properly, we had drawn up a machining range for
each part to enable the part to be handled properly during machining.
We also had to calculate the speed required for drilling.
N=(1000*Vc) / (π*D)
