Research Groups

Machining Research Group (MRG)
The Machining Research Group (MRG) at NCAIR is pursuing state-of-art research in machining processes for aerospace applications. The focus is on optimisation of machining processes for advanced metallic materials such as Titanium, Inconel, and Heat Resistant Super Alloys so that overall cycle times can be reduced while ensuring the required quality is attained. This involves physics-based modelling of the machining process incorporating aspects of:

  • material behaviour of the part being machined, and machining parameters
  • geometric and material characteristics of the cutting tool and tool wear
  • tool path analysis and optimisation
  • machine dynamics and tool vibrations
  • machined surface quality

The research further involves studying the interplay between these aspects, and how the process can be modeled accurately and subsequently optimised to achieve reduced cycle times and improved quality.

The Advanced Machining Excellence Cell (AMEC) at NCAIR is a state-of-art machining experimentation facility which houses a DMG Mori DMC 125FD duoblock 5-axis machine with Sandvik Coromant cutting tools. The machine has a mill-turn configuration which gives the capability to perform both milling as well as turning operations in the same setting. The machine is also instrumented with dynamometers for in-situ measurement of cutting forces and torques during machining operations. This facility is used extensively for model validation and machining process optimisation studies.

Advanced Composites Group (ACG)
The Advanced Composites Group (ACG) at NCAIR, comprising of two sub-groups experimental and computational modelling, studies the behaviour of aerospace grade fibre composites to analyse the materials and technology used in composite manufacturing. The experimental team is involved in the making of composite parts and prototypes at ACG's Composite Manufacturing Laboratory. Additionally, it also performs material characterisation at state-of-the-art microscopy laboratories at IIT Bombay. The computational team works on simulation of critical manufacturing challenges pertaining to the complex multi-physics phenomena that drive the resin infusion process, coupled with curing and fluid-structure interaction.

FATIGUE MODELING GROUP (FMG)
This group focuses on research in Fatigue and damage tolerance of advanced structural systems, and the development of necessary computational methods and tools to meet the structural integrity compliance of aircraft components.

Mechanical Design Group (MDG)
This group is responsible for design, development and improvements of existing and new mechanical systems. Design constraints can be weight, Materials, Fatigue, Fracture and shocks given in standards like MIL etc. Materials we deal with are CFRP, GFRP, Titanium, Invar, Inconel and aluminium foams. Group uses software packages for modelling and analysis and comparesthe results obtained with experiments carried out inside the IITB facilities.

SOFTWARE APPLICATION AND DESIGN GROUP (SA&DG)
SA&DG works collaboratively with all other groups and Involved in development of advanced software applications related toaerospace manufacturing to help partners in the aerospace and other high-value industries.
