Mechanical, Industrial and Manufacturing Engineering

Manufacturing Processes and Systems

The Manufacturing and Industrial Systems focus group concentrates engineering efforts in solving industrial and manufacturing problems. Example problems include planning and modeling the manufacturing system, forecasting industrial needs for materials, determining the best ways to transport goods to customers, development of processes for products, a basic understanding of metal forming and cutting, the design of assembly systems and improving the environmental impacts of industry. A key aspect of this program is the blend of practical plant expertise with the benefits of computational technologies including computer-aided design and manufacturing. Processes are understood from a hands-on perspective and expanded through theoretical defining models. Engineering materials are studied throughout their life cycle from raw material acquisition, product creation and usage, remanufacturing, recycling and final material disposal. Key expertise within this group include internationally recognized faculty in computer-aided design and manufacturing abrasives engineering, facilities planning and modeling and environmentally conscious design and manufacturing, rapid prototyping, system optimization, artificial intelligence, process engineering, grinding and abrasives engineering, facilities planning and modeling and environmentally conscious design and manufacturing.

Current Research Projects

Joining of Light Metals - Dr. Zhang
Light metals have been extensively used in the automotive industry for weight reduction in the last two decades, in order to reduce emission and improve fuel economy, and aluminum alloys are the most promising candidate for this purpose. As the enabling technology, welding aluminum has been a challenge for the welding practitioners. As a result, a large portion of aluminum joining is performed through alternative joining approaches. A number of mechanical joining techniques for joining difficult-to-weld and dissimilar light metals have been researched at UT. For instance, impact self-piercing riveting and friction-stir riveting were developed in the materials joining lab. Such efforts in welding/material joining are critical for the use of aluminum in large volume production, resulting in significant economic and environmental benefits to the society. Standard mechanical testing and metallographic examination techniques are employed in the research. 
Single-phase antibacterial phosphate coatings on orthopedic implants - Dr. Bhaduri
Internal fixation devices like hip or knee implants are widely used in the healthcare industry. With the high usage, surgical site infections (SSI) have also become common and they create havoc in the orthopedic industry. Various biotechnological coatings have been developed over time to curb SSI. However, prolonged usage of antibiotics, instability of composite coatings and processing complexities have hindered their optimized performance. The present project takes advantage of an inorganic element as the antibacterial agent and aims in optimizing its content. These are doped into conventional and non-conventional bioceramics. Fabrication of single-phasic system is of prime concern here as single-phasic systems support the homogeneous release of the dopant.  The single-phasic coatings are formed on various kind of implant materials. Antibacterial effects against common and deadly infection-causing gram-negative and gram-positive bacterial strains are being studied. 
Next-generation calcium phosphate bone cement for orthopedic applications - Dr. Bhaduri
Calcium phosphate bone cement (CPCs) is a widely used commercial orthopedic material. However, unfavorable mechanical properties such as low compressive strength restrict the use of CPCs for repair in maxillofacial and craniofacial defects. To increase the application of CPCs as load-bearing implants in vertebroplasty (VP) and kyphoplasty (KP), compositions with enhanced mechanical properties should be developed. In the present study, primarily we develop injectable CPC with enhanced mechanical properties using two different bio-ceramic reinforcement- both with different aspect ratios. The aims are to seek improvement of compressive strength while retaining good injectability and self-setting nature of the cement. The main hypothesis is to promote the crack deflection toughening mechanism in compositions, while also enhancing bioactivity and cytocompatibility with pre-osteoblast cells.
Magnetic injectable self-setting calcium phosphate cement (CPC) compositions for hyperthermia treatment of bone tumors - Dr. Bhaduri
Human bone is the major site of metastasized cancer tumor cells. Frequently, abnormal activity of osteoclast cells causes tumors known as sarcomas. Common treatments for sarcomas include surgery, radiation therapy, and chemotherapy. However, most of these treatments are highly invasive, non-responsive, and result in significant collateral damage. An alternative therapy, hyperthermia involves increasing the tumor-site temperature above the normal body temperature without affecting the neighboring tissues. This project deals with the development of a self-setting magnetic calcium phosphate cement for hyperthermic ablation of bone tumors. The magnetic compositions are achieved by doping injectable, self-setting calcium phosphate cement (CPC) compositions with iron. This makes it radio-opaque, thus ensuring that the cement can be injected at the correct location. Further, the subsequent application of an external AC electric field can generate substantial heat in the cement without the application of any electrode and any surrounding tissue damage. The self-setting property ensures that the cement sets (hardens) at the appropriate location. The results reveal satisfactory self-setting nature, biocompatibility and also serve the purpose of killing cancer cells. 
Smart piezoelectric calcium phosphates for orthopedic, spinal-fusion and dental applications - Dr. Bhaduri
This project reports the development of a new generation of smart injectable calcium phosphate cement (CPC) for orthopedic applications. The “smart” aspect of the compositions is achieved by incorporating piezoelectric materials in the cement compositions. This eliminates the requirement of high-temperature sintering process and the fabrication of simple shapes, and enable the cement to be injected at the defect site using a minimally invasive procedure. The targeted properties are to achieve good compressive strength, injectability, bioactivity, biocompatibility, and even washout resistance. The properties of this cement should not be compromised with the incorporation of piezoelectric materials.
