## GUJARAT TECHNOLOGICAL UNIVERSITY ## Program Name: Diploma Engineering ## Level: Diploma Branch: Mechanical Engineering Subject Code: DI05019031 Subject Name: Computer Aided Design and Manufacturing w. e. f. Academic Year: 2026-27 Semester: 5 th Category of the Course: PEC-03 -  Basic engineering graphics and 2D/3D modeling -  Fundamentals of manufacturing processes -  Basic computer knowledge -  Exposure to AutoCAD/3D modeling (covered in Sem 4) Rationale: This course builds upon prior knowledge of 3D modeling (covered in Semester 4 ) and focuses on advanced CAD/CAM and CNC machining concepts. It aims to bridge the gap between design and manufacturing by providing hands-on exposure to CNC programming, CAM toolpath generation, and digital manufacturing workflows. The course aligns with Industry 4.0 practices and prepares students for modern production environments. ## After Completion of the Course, Student will able to: | No | Course Outcomes | |------|---------------------------------------------------------------| | 01 | Apply advanced CAD techniques for complex product design | | 02 | Explain construction and working of CNC machines | | 03 | Develop CNC part programs for turning and milling operations. | | 04 | Generate and simulate CAM toolpaths | | 05 | Integrate CAD-CAM-CNC workflow in manufacturing | ## Teaching and Examination Scheme: | Teaching Scheme (in Hours) | Teaching Scheme (in Hours) | Teaching Scheme (in Hours) | Total Credits L+T+ (PR/2) | Assessment Pattern and Marks | Assessment Pattern and Marks | Assessment Pattern and Marks | Assessment Pattern and Marks | Total Marks | |-------------------------------|-------------------------------|-------------------------------|------------------------------|--------------------------------|--------------------------------|--------------------------------|--------------------------------|----------------| | L | T | PR | C | Theory | Theory | Tutorial / Practical | Tutorial / Practical | | | | | | | ESE (E) | PA(M) | PA(I) | ESE (V) | | | 3 | 0 | 2 | 4 | 70 | 30 | 20 | 30 | 150 | Page 1 of 4 Prerequisite: ## GUJARAT TECHNOLOGICAL UNIVERSITY ## Program Name: Diploma Engineering Level: Diploma Branch: Mechanical Engineering Subject Code: DI05019031 Subject Name: Computer Aided Design and Manufacturing ## Course Content: | Unit No. | Content | No. of Hours | % of Weightage | |-------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------|-----------------|-------------------| | | CAD/CAM Fundamentals | | | | 1. | 1.1 CAD/CAM overview and integration 1.2 Digital manufacturing concept 1.3 Applications in industry | 04 | 9 | | 2. | Advanced Geometric & Parametric Modeling 2.1 Feature-based modeling 2.2 Surface modeling 2.3 Advanced assembly (top-down approach) 2.4 Design intent & constraints | 08 | 18 | | 3. | CNC Machine Technology 3.1 CNC architecture 3.2 Drives and feedback systems 3.3 Tooling and workholding 3.4 CNC setup and calibration | 07 | 16 | | 4. | CNC Programming 4.1 Advanced G & M codes 4.2 Turning & milling programs 4.3 Tool compensation 4.4 Subprograms and macros | 10 | 22 | | 5 | CAM & Toolpath Generation 5.1 CAM workflow 5.2 Toolpath strategies (roughing, finishing) 5.3 Tool selection & parameters 5.4 Simulation & verification | 07 | 16 | | 6 | CAD-CAM Integration 6.1 Model to machining workflow 6.2 Post-processing 6.3 CNC data transfer (DNC) | 05 | 11 | | 7 | Recent Trends in CAD/CAM 7.1 Industry 4.0 7.2 Digital Twin 7.3 Additive Manufacturing 7.4 Automation integration | 04 | 8 | | | Total | 45 | 100 | Page 2 of 4 ## GUJARAT TECHNOLOGICAL UNIVERSITY ## Program Name: Diploma Engineering ## Level: Diploma Branch: Mechanical Engineering Subject Code: DI05019031 Subject Name: Computer Aided Design and Manufacturing ## Suggested Specification Table with Marks (Theory): | Distribution of Theory Marks | Distribution of Theory Marks | Distribution of Theory Marks | Distribution of Theory Marks | Distribution of Theory Marks | Distribution of Theory Marks | |--------------------------------|--------------------------------|--------------------------------|--------------------------------|--------------------------------|--------------------------------| | R Level | U Level | A Level | N Level | E Level | C Level | | 10 | 20 | 40 | 00 | 00 | 00 | Where R: Remember; U: Understanding; A: Application, N: Analyze and E: Evaluate C: Create (as per Revised Bloom's Taxonomy) ## References/Suggested Learning Resources: | Sr. No | Title of Book | Author | Publication with place, year and ISBN | |-----------|-----------------------------------------------------|----------------------------------------|------------------------------------------| | 1 | CAD/CAM Principles and Applications | P.
