Thermal errors have the largest contribution, as much as about 70%, to the machining inaccuracy of computer-numerical-controlled (CNC) machining centers. The error compensation method so far plays the most popular and effective way to minimize the thermal error. How to accurately and quickly build an applicable thermal error model (TEM) is the kern...

The aim of our project is to design and fabricate a pneumatically operated tapping machine is called universal tapping machine. This device is operated by compressed air. It consists of the following main parts.
1. Barrel
2. Shaft
3. bearing
4. Couplings, etc.
A high pressure compressed air is forced on a fan and the fan is made...

The aim of our project is to design and fabricate a pneumatically operated multipurpose grinder. With this device a number of operations can be performed. A high pressure compressed air is forced on a fan and the fan is made to rotate. This rotation is transmitted to the machining head by a shaft and the required operation is carried out. Furthe...

Multi tool turret head is used to make more operations like drilling, facing, turning; chamfering, grooving etc… are done sequentially. It has proved to be the most versatile method to machining works on the work piece. This machine includes a first functional portion known as the work holder which helps to hold the work piece. This system is provi...

Aging-induced degradation imposes a major challenge to the designer when estimating timing guardbands. This problem increases as traditional worst-case corners bring over-pessimism to designers, exacerbating competitive and close-to-the-edge designs. In this work, we present an accurate machine learning approach for aging-aware cell library cha...

Planar, double-side cooled power modules are emerging in electric-drive inverters because of their low profile, better heat extraction, and lower package parasitic inductances. However, there is still concern about their reliability due to the rigid interconnection between the device chips and two substrates of the power module. In this paper, a po...
