Academic Year 2023/2024 - Teacher: Sergio FICHERA

Expected Learning Outcomes

The expected learning outcomes are:

- knowledge of the main manufacturing processes for plastic deformation, for foundry, for chip removal and for joining metal parts

- the ability to analytically solve technological problems in order to allow students to carry out an adequate constraints/opportunities analysis

- the ability to evaluate manufacturing processes in order to independently arrive at the selection and optimization of the most suitable process and materials

- the use of numerical methodologies for the analysis of plastic deformation and chip removal processes

Course Structure

frontal or remote lessons

For each module, the development of application cases is envisaged using Excel and VBA

Required Prerequisites

Knowledge of basic mathematical notions is required for the calculation of derivatives and integrals

Learning Assessment

Learning Assessment Procedures

The exam is only written with quantitative and non-quantitative questions. The test lasts 60 minutes. Usually 6 questions. Each question is associated with a maximum score. The overall grade is the sum of the scores for the individual questions. Scores are announced at the beginning of the assignment. At the end of the course, training tests for the exam task are carried out.

Examples of frequently asked questions and / or exercises

1 Indicate with a indicate with drawings the steps in the production sequence in Permanent-­‐Mold Casting Processes.


2 Indicate at least 4 characteristics for the design of the pattern.


3. Indicate the difference between turning and orthogonal cutting. Drawn the two operation and sign the parameters.


4 Indicate at least 4 characteristics of the materials for turning tools.


5 A cylindrical roughing of 50 steel bars must be performed on the lathe. The caratheristics of the bar: length 500 mm, diameter 134 mm, final diameter 130 mm, Kso 1200, z 0.197, angle of attack ꭓ= 90. The absorbed power is equal to 6 KW. The tool change time is 5 min (C 350 m / min, n 0.25) Calculate the the total minimu time to perform all bars and the total energy consumed.
