MANUFACTURING TECHNOLOGY MANAGEMENT
Academic Year 2023/2024 - Teacher: Sergio FICHERAExpected Learning Outcomes
The course deals with the description of the most used technological processes in the industrial field for the processing of metal materials and the basic elements for the management of production systems.
The expected results are:
• knowledge of the main manufacturing processes for foundries, 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 metallic materials and 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 chip removal processes
• the ability to use statistical methods for quality control
• the ability to solve process scheduling problems

Learning Assessment
Learning Assessment Procedures
The exam is only written with quantitative and non-quantitative questions. The test lasts 120 minutes. Usually 9 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 Indicate the meaning of ARL1, show the calculus with the formula and a drawn.
6 Indicate the criteria to select the deep of cut
7 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.
