The process and possibilities of technological planning for lathe centers, 3D, and 5D milling machines. Introduction to the main parts, units, and applied control technology elements of such machines. Technological planning for CNC-controlled lathes with "C" axis and sub-spindle. Overview and application of polar coordinate interpolation, cylindrical interpolation, spline interpolation, and NURBS interpolation. Main steps of shop-floor (conversational) programming. Tools, analysis, interpretation, and demonstration of measurements on CNC machines. Running CAM software-generated programs in an industrial environment. Basics of parametric and macro programming. Overview of tasks solved with parametric programming. Main components of industrial robots (drive, gripper, sensors, etc.).
Course content - labs:
Knowledge:
Introduction to the CNC machines and related tools used during the semester, and the presentation of safety regulations related to their operation. Manufacturing sample tasks on CNC-controlled lathes with "C" axis and sub-spindle. Operation of CNC machines. Independent tool measurement and workpiece zero point setting under supervision. Modeling tasks using "RE" techniques in groups of 2-3. Presentation of tasks created parametrically. Manufacturing of parts programmed parametrically.
Students are committed to precise and accurate work, and are open to learning new technologies and innovations in the field of CNC technology and industrial robotics. They willingly collaborate with their peers and actively participate in group projects. They approach their tasks responsibly, adhere to safety regulations, and ensure the safety of others in the workshop, striving to perform quality work.
Students are capable of operating CNC machines, performing technological planning, applying interpolation methods, shop-floor programming, using CAM software, and conducting parametric and macro programming.
Students independently operate and maintain CNC machines, solve technical problems, and perform tool measurement and workpiece zero point setting. They are responsible for correctly creating and presenting parametric programs, as well as completing and presenting modeling tasks in groups. They ensure the quality and efficiency of manufacturing processes, adhere to safety regulations, and prioritize the safety of their peers in the workshop. They seek assistance and consult on professional issues when necessary.
Mid-term study requirements:
Writing the first midterm exam is mandatory. There is one opportunity to make up the exam during the active semester. The duration of the exam is 60 minutes, and the maximum score is 100 points. The passing grade is 50 points, average is 61 points, good is 76 points, and excellent is 86 points. The exam includes both CNC programming and theoretical questions. The practical grade is determined based on the midterm exam; however, a student cannot receive a valid practical grade if their programming assignment is not accepted by the end of the active semester. Throughout the semester, students must complete three programming assignments (for a sub-spindle lathe, a "C" axis task, and one that can be solved with parameterized programming). These assignments must be submitted in person to the instructors, and students must be prepared to answer questions related to the completion of the tasks.
