The Computer Aided Design and Computer Aided Manufacturing are the modern innovative technology in garments manufacturing like all other manufacturing sectors. Garments CAD is specially used for pattern designing and marker making. On the other hand CAM is used for fabric cutting and other manufacturing sections. Before implementing those new technologies, manual system was widely used in garments sector. In recent time some large garments factories of Bangladesh are starting to adopt CAD and CAM technology. Beside that a huge number of medium and small size factories are using manual system yet. This paper presents a feasibility study of CAD and CAM technology in above mentioned different size factories in Bangladesh. The Study is carried out in respect of production procedure, required man power, production/hr, product quality, production efficiency, and production cost. The practical investigation and data shows the scenario that all types of garments industries are not capable to use CAD & CAM and also not even profitable for them.
