Professional Experience:

Employer Position Pay scale Period Responsibilities

Water Deputy 156**-***** April 2013- to Project planning and execution work

Resource Engineer 5400(GP) Present of heavy mechanical structure

Department Deputy 156**-***** Oct. 2007- to Administration of workshop

Maharashtra Engineer 5400(GP) Dec. 2010 manufacturing EOT cranes and hoist.

Government Assistant 9300-34800 Jan.2002- Supervision on erection and running

Engineer 4600(GP) Sept.2007 of Lift Irrigation Schemes with 650

HP vertical turbine pumps.

As a Deputy Engineer (from April 2013 to Present):

Administration on a unit engaged in errection, operation and maintenance of radial gates and

their hoist and allied parts on the dams. This job includes execution and coordination of activities

to erect the heavy mechanical parts. It requires a skill of project planning and execution to

complete project in a scheduled time. In addition, this job involves operation and maintenance of

material handling equipments.

As a Deputy Engineer (from October 2007 to December 2010):

Administration of workshop manufacturing EOT cranes, emergency gate hoists required to lift

hydraulic gates of dams under Maharashtra government. The job involves planning,

organization, scheduling of the activities to complete the job in a shortest period of time. The

activities involve manufacture, assembly and quality control of various components and

subassemblies of hoist assembly. Hoist parts consists of casting of cast steel and cast iron drum,

gears etc, their machining, groove and teeth cutting, fabrication of mild steel structural parts.

Inspection involves nondestructive testing of cast parts, welded joints. Quality assurance

involves dimensional and working specifications testing. The jobs also include operation and

maintenance of machines, trucks and material handling equipment required for the workshop.

From 2007-2010, 80 cranes of capacity ranging from 10 Ton to 60 Ton with a total tonnage of

1200 M Ton manufactured. These cranes are used to lift hydraulic gates of dams under

Maharashtra Government (India).

As a Assistant Engineer (from Jan. 2002 to August 2007):

My job profile includes design, erecting, maintenance and operation of lift irrigation scheme

which involves 650 to 1050 HP vertical turbine pumps. These pumps are used to lift water from

the river and to deliver it to the areas of higher altitude for irrigation purpose. My job profile

involves determination of number of pumps to ensure required discharge, specification of pumps

and allied parts, errection, commissioning and operation of vertical turbine pumps and its allied

parts. This job requires liaisoning with civil construction authorities and pump manufacturing

company.

Project details:

Ph.D. Thesis Title: Analysis of chip segmentation and its microstructure in machining of

titanium alloys

• Demonstrated influence of β phase fraction on grain deformation in the shear zone as

well as on the characteristics of shear bands generated during machining.

• Demonstrated through microstructure inside the shear band, that the material does not

undergo dynamic recrystallization during formation of shear bands.

• Demonstrated that the mechanisms of segment formation can be changed from plastic

strain to fracture. Also, demonstrated the influence of segment forming mechanism on the

machinability of titanium alloys.

• Demonstrated influence of machining environments and β phase fraction on surface

integrity of machined surface.

M.Tech. thesis title: “Debottlenecking and real time production planning through study of

constraints.” The project is based on ensuring full utilization of critical resources to meet

production target.

B.E. thesis title: “KAIZEN”. A study project on methods to achieve continuous improvements in

the work environment.

Relevant Courses during Ph. D.
