EDUCATIONAL GOALS
THE COURSE PROVIDES THE BASIC CONCEPTS RELATED TO THE NON-CONVENTIONAL MANUFACTURING PROCESSES, TO THE CONVENTIONAL AND NON-CONVENTIONAL PERMANENT JOINTING TECHNIQUES, REFERRING ALSO TO THE THERMAL TREATMENTS OF MECHANICHAL STRUCTURES AND TO THE NON-DESTRUCTIVE TESTING.

KNOWLEDGE AND UNDERSTANDING.
AT THE END OF THE COURSE, THE STUDENT KNOWS:
- NON-CONVENTIONAL MANUFACTURING PROCESSES;
- SOLID STATE AND FUSION WELDING;
- THERMAL TREATMENTS AND TO THE NON-DESTRUCTIVE TESTING OF MECHANICHAL STRUCTURES.

APPLIED KNOWLEDGE AND UNDERSTANDING
AT THE END OF THE COURSE, THE STUDENT IS ABLE TO:
- IDENTIFY THE MOST APPROPRIATE NON-CONVENTIONAL PROCESS TO REALIZE SPECIFIED SURFACES
- IDENTIFY THE SUITABLE WELDING TECHNIQUES FOR THE JOINTING OF MECHANICAL COMPONENTS
- DEFINE THE THERMAL TREATMENT AND THE NON-DESTRUCTIVE TESTING TO VERIFY A MECHANICAL COMPONENT OR STRUCTURE

AUTONOMY OF JUDGMENT
BEING ABLE TO IDENTIFY THE MOST APPROPRIATE MANUFACTURING, THERMAL TREATMENT AND INSPECTION STRATEGIES TO REALIZE OR VERIFY SURFACES MEETING THE SPECIFIC DESIGN REQUIREMENTS.

COMMUNICATION SKILLS
BEING ABLE TO DESCRIBE, IN WRITTEN FORM, IN A CLEAR AND CONCISE WAY AND ORALLY PRESENT THE OBJECTIVES USING TECHNICAL-SCIENTIFIC LANGUAGE, THE PROCEDURE AND THE RESULTS OF THE PERFORMED ELABORATIONS.

LEARNING SKILLS
BEING ABLE TO APPLY THE KNOWLEDGE ACQUIRED IN CONTEXTS DIFFERENT FROM THOSE PRESENTED DURING THE COURSE, AND TO DEEPEN THE TOPICS COVERED USING MATERIALS OTHER THAN THOSE PROPOSED.
Prerequisites
KNOWLEDGE OF THE FUNDAMENTS OF THE MATERIALS SCIENCE AND THE CONVENTIONAL PROCESSING TECHNOLOGIES IS REQUIRED.
Contents
WELDINGS (THEORY HOURS 15, EXERCITATIVE HOURS 5, LABORATORY HOURS 5)
GENERALITIES ON FUSION WELDINGS (GAS, ELECTRIC ARC, PLASMA, LASER, PRESSURE AND RESISTANCE WELDINGS), SOLID-STATE WELDINGS (FRICTION, ULTRASOUND, ELECTROMAGNETICAL PULSES WELDINGS), TESTING OF WELDED JOINTS.
THERMAL TREATMENTS AND NON-DESTRUCTIVE TESTING (THEORY HOURS 15, LABORATORY HOURS 5)
DIFFUSIVE AND NON-DIFFUSIVE TRANSFORMATIONS, THERMAL TREATMENTS. DYE PENETRANT INSPECTION, MAGNETOSCOPY, X-GRAPHY, TOMOGRAPHY.
NON-CONVENTIONAL MANUFACTURING PROCESSES (THEORY HOURS 10, LABORATORY HOURS 5)
SHEET FORMING, ELECTRICAL DISCHARGE MACHINING, ELECTROCHEMICAL MACHINING, WATERJET.

Teaching Methods

THE COURSE IS STRUCTURED IN THEORETICAL LESSONS AND CLASSROOM EXERCISES INTEGRATED WITH LABORATORY VISITS AND PRACTICAL DEMONSTRATIONS OF MECHANICAL PROCESSING AND MEASURING CYCLES.
THE THEORETICAL LESSONS SHOW THE NON-CONVENTIONAL MANUFACTURING TECHNIQUES, WELDING PROCESSES, THERMAL TREATMENTS AND NON-DESTRUCTIVE TESTS.
THE EXERCISES ARE AIMED AT THE ASSESSMENT OF WELDED JOINTS.
THE DEMONSTRATIONS IN THE LABORATORY ARE AIMED AT PROVIDING A PRACTICAL REVIEW OF THE THEORETICAL NOTIONS EXPLORED IN THE THEORETICAL LESSONS.
Verification of learning
THE EVALUATION OF THE ACHIEVEMENT OF THE OBJECTIVES WILL TAKE PLACE BY A WRITTEN TEST AND AN ORAL INTERVIEW WHERE THE DEGREE OF KNOWLEDGE ACQUIRED AND THE ABILITY OF EXPOSURE OF THE DISCUSSED TOPICS WILL BE ASSESSED. THE TOTAL ASSESSMENT IS EXPRESSED IN THIRTYTHS.

IN ORDER TO ACCESS THE ORAL EXAM, THE WRITTEN TEST MUST BE PASSED AT LEAST WITH A MINIMUM SCORE OF 18/30. THE WRITTEN TEST CONSISTS OF THE DRAWING UP OF A PART PROGRAM, RELATING TO TURNING, MILLING AND DRILLING OPERATIONS, TO BE CARRIED OUT WITHIN A TIME LIMIT OF TWO HOURS. DURING THE ORAL TEST IS ALSO REQUIRED THE PRESENTATION OF AN ELABORATE DEVELOPED DURING THE COURSE DEEPENING THE SPECIFIC THEMES.
THE EVALUATION OF THE TESTS TAKES INTO ACCOUNT THE ABILITY TO IDENTIFY THE MOST APPROPRIATE WORKING STRATEGIES FOR MACHINING MECHANICAL COMPONENTS, THE ABILITY TO CLEARLY AND CONCISELY EXPOSE THE OBJECTIVES, THE PROCEDURE AND THE RESULTS OF THE ELABORATIONS PERFORMED, AS WELL AS THE ABILITY TO DEEPEN THE TOPICS COVERED USING MATERIALS OTHER THAN THOSE PROPOSED.
THE MINIMUM ASSESSMENT LEVEL (18/30) IS ATTRIBUTED WHEREAS THE STUDENT DEMONSTRATES A SCARCE UNDERSTANDING OF THE NUMERICALLY CONTROLLED MACHINES AND OF THE RELATED PROGRAMMING, HAS A POOR DISPLAY CAPACITY AND LIMITED AUTONOMY AND JUDGMENT.
THE MAXIMUM LEVEL (30/30) IS ATTRIBUTED WHEREAS THE STUDENT DEMONSTRATES A COMPLETE AND IN-DEPTH KNOWLEDGE OF THE ANALYZED INSTRUMENTS AND METHODS AND IS ABLE TO SOLVE THE PROPOSED PROBLEMS BY IDENTIFYING THE MOST APPROPRIATE WORKING AND PROGRAMMING STRATEGIES AND SHOWS A REMARKABLE CAPACITY IN WRITING OF PART PROGRAM
THE FINAL MARK, EXPRESSED IN THIRTIETHS WITH POSSIBLE HONOR, IS OBTAINED AS THE AVERAGE OF THE TWO TESTS.
THE HONOR IS AWARDED WHEREAS THE CANDIDATE DEMONSTRATES SIGNIFICANT MASTERY OF THE THEORETICAL AND OPERATIONAL CONTENTS AND SHOWS HIS ABILITY TO PRESENT THE TOPICS WITH SIGNIFICANT LANGUAGE PROPERTIES AND AUTONOMOUS PROCESSING CAPACITY EVEN IN CONTEXTS OTHER THAN THOSE PROPOSED BY THE TEACHER.
