Course material
Presentations lectures are available on Toledo
Language of instruction: more information
English
Format: more information
Introduction to the general functioning (planning, evaluation, ...) of the OPO. Presentations will be given in preparation of the OLA-practicum. The knowledge acquired during the lectures will be applied in the practical course.
2 ects. Computer-Aided Manufacturing: Lab Session (B-KUL-T4pCM2)




Content
Learning to make a work preparation for CNC machines of complex workpieces
Programming of a CAM system.
Generating the machine language.
Setting up a CNC machine: 3-axis machining (or 5-axis machining).
Performing operations on CNC machines.
Costcalculation of the production.
Course material
Documentation on Toledo, tutorials on the CAM software, videos of the lectures, databases of tool manufacturers, video material related to the operation of the machines, presentations during the practical course.
Format: more information
There are 10 sessions of 3 hours. These take place partly in a computer lab and partly in the lab. The students are assigned in pairs to produce a workpiece. They first make a detailed work preparation and apply this using a CAM software. Afterwards they make the workpiece via a CNC machine.
Evaluation
Evaluation: Computer-Aided Manufacturing (CAM) (B-KUL-T72370)
Explanation
1. Establishment of the final grade
The total point of this OPO is calculated based on the published partial grades with following weights:
- Partial grade for Lecture: 40%
- Partial grade for the Lab sessions: 60%
The only exception to this is described in the faculty supplement to Article 66 of the OER.
2. Establishment of the published component marks
The partial grade for "Lecture" is an integer out of 20. It expresses an assessment of the student's performance based on a written/oral test consisting of open questions and organized before the examination period.
The partial grade for "Lab sessions" is an integer out of 20. It expresses an assessment of the student's performance based on:
Students will deliver a report in pairs: this is a complete bundle containing all the info for a machine operator to produce the intended workpiece. The students deliver a physical workpiece on which a significant part of the operations prepared with the CAM software have been performed. During the final lab session, the students take an individual knowledge test. The lab sessions are evaluated as permanent evaluation throughout the year (bonus/malus +2).
3. Absences
- Unauthorized absence during the exams of the lectures leads to NA as final mark for the lectures.
- Unauthorized absence during one or more of the lab sessions leads to NA as final mark for the lab sessions.
If you are absent during class weeks, notify the education ombuds the same day. Furthermore, contact the teachers with whom you missed compulsory sessions or evaluation moments as soon as possible and certainly within the week. In case of absence during the examination period, inform the examination ombudsperson the same day.
When needed, additional information on the evaluation activities is provided during the lessons and/or made available on the Toledo pages of the course.
If the university decides that it is confronted with situations of general force majeure or situations where the safety and health of members of the academic community of KU Leuven may be endangered and changes to the teaching and evaluation activities occur as a result, these changes will be communicated via Toledo.
Information about retaking exams
This course unit allows partial mark transfers in case of partial pass mark:
- T4hCM2 - Computer-Aided Manufacturing: Lecture (during and beyond academic year)
- T4pCM2 - Computer-Aided Manufacturing: Lab Session (during and beyond academic year)
Within this course there are partial transfers in case of a successful partial result (>10/20), if not successful there is a re-examination possible in the third exam period:
-T3hCM1 - Computer-aided manufacturing: lecture => Written exam with open questions.
-T3pCM1 - Computer-aided manufacturing: lab session => The student makes an alternative work preparation with the CAM software without execution on the machine and is presented orally. The student also retake the individual knowledge test. The permanent evaluation score earned during the first semester wil be maintained.
