Experienced Mechanical Engineer with a solid background in design, calculation, detailing, and manufacturing processes. Capable of developing original solutions anticipating the design consequences and completing projects to specifications in the first attempt. Possess project management and team management skills, enabling successful interaction with customers, suppliers, and co-workers.

SKILLS AND TECHNIQUES

Mechanical design:
long experience in the design, from cradle to grave, of a variety of machineries and mechanical devices, and in specific:
• Complete design of CNC tool machines, including CNC spindle units, rotary tables, chucks and part-holding equipments, pneumatic and hydraulic systems, chip conveyor systems, automatic loading systems with robots, bedplates, welded metal structures and protection guards;
• Design of special machines and material handling equipments.
• Design of large capacity overhead cranes.
As part of the design process developed experience in:
• Design and sizing of motor driven and hydraulic servo systems.
• Design of pneumatic and hydraulic systems.
• Selection of appropriate market available components.
• Selection of machined parts materials and heat treatments.
• Design of safety equipment in compliance with the European Machine Directive 2006/42/EC.
• GD&T according with ISO and ASME Y14.5-2009 standards; DFMA.
• Solid understanding of form fit & function and tolerance stack up analysis theory (practice with tools as TolAnalyst/Solidworks and MitCalc).
• Material procurement experience.
• Technical documentation and end user manual writing according with European Machine Directive 2006/42/EC.

Anticipating technical problems:
main experience in the design of special machineries, by their nature prototypes. Been able to make a solid design at the first attempt on several projects, successfully meeting the design requirements. Among the projects, at least 30 tool machines and 10 overhead cranes.

Machine elements calculation:
developed several complex excel calculation spreadsheets that helped myself and my colleagues in selecting and properly sizing the most critical components of the machineries.

Design and calculations of large metal welded structures:
designed girder type bridge overhead cranes based on international standard calculation guidelines.

FEA analysis:
validated several welded structures and mechanical assemblies using Solidworks Simulation.

Team management skills:
in Danieli Centro Cranes managed an increasing team that finally was made of eight people, most of which not experienced in the field and in need of mentoring.

Ability to work with limited or no supervision, efficiently multi-tasking and reprioritizing:
in particular during the time as self-employed I had the chance of developing the ability of being self-reliant and of dealing with strict deadlines. Later on I have been able to successfully apply these skills organizing the job of the design departments I have been in charge. In Danieli Centro Cranes our Design Department had one of the highest productivity of the corporate group.

Ability of effectively support the sales managers:
often met with prospect customers of different countries to present our company and the solution we propose for their technical problem, receiving very positive feedbacks on the presentations and the solidity of our technical approach, eventually receiving purchasing orders.

Software
• Solidworks 2014; Autodesk AutoCAD with Mechanical 6.
• Solidworks simulation, FEA and motion analysis package.
• Word, Excel, PowerPoint.
• Microsoft Access small databases development.
• Visual Basic for Application, particularly in Solidworks, Excel and Access environment.
• AS400.

EXPERIENCE

SPADA TRANSFER TECHNOLOGY, Castegnato, Italy (transfer machines production company) 06/2012 – present

Machinery design
Design of tool machines, including welded machine beds, spindle units, rotary tables, chucks and part handling equipments, pneumatic and hydraulic systems, chip removal and treatment systems, safety guards. All tool machines are customized implementing the “engineer-to-order” manufacturing philosophy. Current job consists of the following activities and responsibilities:
• Create, from the specific needs of the customer, a sound design based on the assigned budget and on the required productivity and accuracy of the machine.
• Ensure the Sales Department receives appropriate technical support such as reviewing of contract specification and customer guidelines, rough drafts of the machine design for budget definition, presentations for final customers and active partaking in the meetings prior to the purchase of the machine.
• Create newly designed machines minimizing costs while maintaining appropriate quality and performances and, for such purpose, try to maximize the technological carry-over using previously produced and tested sub-assemblies and, where not possible, create new devices and assemblies.
• Apply engineering calculations to properly select and size commercial and manufactured components. Create Excel spreadsheets available to other designers for prompt validation of their own component selections.
• Create assembly drawings with bill of materials and detail drawings of the manufactured parts.
• Create assembling and testing instructions for the workshop.
• Develop a machining cycle by selecting the appropriate working tools and working parameters.
• Work directly with the Industrialization and Purchasing Department to optimize the final design following strict DFMA guidelines.
• Material procurement and supplier evaluation in collaboration with the Purchasing Department.
• Support the Electronics and Software Department engineers in the development of the on-board electronics, the electrical equipment, and the customized software based on ISO CNC language.
• Provide project management for the whole production process, ensuring that all departments receive prompt and precise information, and address issues that arise during the production process with quick and cost effective responses.
• Serve as a reliable reference for the Sales Department and the customer during all the steps of the production process.
• Supervise machine final tests with customer technicians.
• Write end user manuals.

Design Department organization

As the company transitions from a very small to a medium sized company, the Design Department has to conform its working guidelines to provide technical documentation suitable for appropriately serving all its departments.
In light of previous similar experiences I have been put in charge of implementing the following:
• Formalize job order work-flow.
• Create an accessible but solid document storage policy.
• Design a new part coding.
• Write guidelines for Solidworks use enabling the maximum re-usability of sub-assemblies and the automatic creation of complete bills of material.
• Create Solidworks macro programs in VBA to automatically connect Solidworks BOM creation to the existing corporate ERP software.
• Create Solidworks productivity tools in VBA language.
• Review the guidelines for end user manual writing in light of European Machine Directive 2006/42/EC requirements.
