Basics Of Precision Engineering

Examines design, selection, and combination of machine elements to produce a robust precision system. Introduces process, philosophy and physics-based principles of design to improve/enable renewable power generation, energy efficiency, and manufacturing productivity. Topics include linkages, power transmission, screws and gears, actuators, structures, joints, bearings, error apportionment, and error budgeting. Considers each topic with respect to its physics of operation, mechanics (strength, deformation, thermal effects) and accuracy, repeatability, and resolution. Includes guest lectures from practicing industry and academic leaders. Students design, build, and test a small benchtop precision machine, such as a heliostat for positioning solar PV panels or a two or three axis machine. Prior to each lecture, students review the pre-recorded detailed topic materials and then converge on what parts of the topic they want covered in extra depth in lecture. Students are assessed on their preparation for and participation in class sessions. Students taking graduate version complete additional assignments. Enrollment limited.

Basics of precision engineering


The demand for precision components is on the rise in a variety of engineering industries. Over the last 10 years, ultraprecision manufacturing technology has been applied on an industrial scale to ultraprecision production of products such as mobile phones, security monitor systems, head-up displays (HUD) and varifocal lenses, etc. However, it has always been a challenge for engineering science to support high-precision exploration and application, and the industrial scale-up has further increased those challenges.

As a result, it has never been so important to understand the fundamentals in engineering science and key enabling precision engineering technologies that drive ultraprecision manufacturing from small batch machining towards industrial scale production. A holistic precision engineering approach and the associated scientific understanding are desired and thus able to bridge these gaps in a seamless and sustainable manner.

Mechatronics consists of synergistic interaction among various engineering disciplines (mechanics, control, micro-electronics, computing, etc.) geared towards integrating functionalities in machines or devices.

Yet the concept of precision engineering includes the design and development of machines and devices following basic principles geared towards prioritising precision over any other requirement.

Precision machining is a manufacturing process. People use it to produce hundreds of both small and large objects that we use daily. Every intricate component that makes up part of a larger object usually requires the work of a precision machinist.

Precision CNC machining works by removing excess raw materials to result in a finished product. The process is highly accurate, and uses a range of different processes. This is to achieve the highest levels of precision and quality every time.

It is very likely that most of the objects we use in day-to-day life have been precision machined in some way. From everyday appliances and car parts, through to surgical instruments and aerospace components. This shows that almost every industry has benefited from this process.

Here at PT Engineers, we are proud to offer a wide range of CNC machining capabilities in-house.

As major as the 4-20 mA loop standard has become in the process control industry, many do not understand the fundamentals of its setup and use. Not knowing the basics could potentially cost you money when it comes time to make decisions about process display and control. Having a grasp on the history, workings, pros and cons of the 4-20 mA loop will help you to understand why it is the dominant standard for the industry and allow you to make informed decisions about your process control.

In order to understand what a 4-20 mA direct current (DC) loop is and how it works, we will need to know a little bit of math. Don't worry; we won't be delving into any advanced electrical engineering formulas. In fact, the formula we need is relatively simple: V = I x R. This is Ohm's Law. What this is saying is that the voltage (V) is equal to the current (I) multiplied by the resistance (R) ("I" stands for Intensité de Courant, French for Current Intensity). This is the fundamental equation in electrical engineering.

Precision engineering and manufacturing issues are becoming ever more important in current and future technologies. New knowledge in this field will aid in the advancement of various technologies that are needed to gain industrial competitiveness. To this end the International Journal of Precision Engineering and Manufacturing (IJPEM) aims to disseminate relevant fundamental and applied research works of high quality to the international community through efficient and rapid publication.

The Korean Society for Precision Engineering (KSPE) was founded in 1984 and consists 10 technical divisions. Each division of the society contributes to national industrial development in precision engineering and technology area in various ways. The society publishes the International Journal of Precision Engineering and Manufacturing (IJPEM) and this journal is one of the major journals in precision engineering and manufacturing fields. From the IJPEM, emerging "green manufacturing" field was split to launch the IJPEM-Green Technology (IJPEM-GT) in 2014. Furthermore, the International Symposium on Green Manufacturing and Applications (ISGMA, has been organized mainly by KSPE every year since 2011. In 2018, ISGMA was renamed to International Symposium on PRecision Engineering and Sustainable Manufacturing (PRESM, to expand the scope of the symposium to cover a wider range of topics related to green manufacturing, including precision engineering.

Mathematical modeling and wet-lab engineering revealed how genetic tuning shapes biosensor function. Our findings enable precision engineering of gene circuits for basic science and microbial cell factories.

Biosensors bind to an inducing metabolite and alter gene expression by binding to the DNA. Their overall input-output behavior can be represented by a dose-response curve. Two key features of response curves are their dynamic range and sensing threshold. These two parameters determine the strength of biosensor output for various input concentrations. In synthetic biology, genetic engineering is typically employed to shape dose-response curves to a desired specification. Our experiments revealed that changes to the sensor-DNA interaction affect both dynamic range and threshold simultaneously. This indicates the existence of trade-offs between the ability to either sense low chemical abundance or increase biosensor output. We used mathematical models to elucidate the interdependencies between the dose-response curves and genetic modifications. Combining model analysis and genetic engineering, we found two tuning dials that allow for independent control of the dose-response parameters.

These findings are crucial for fine-tuning biosensor function through genetic and protein engineering, with applications in basic science as well as the construction of efficient microbial factors for the production of commodity chemicals. Our HFSP Young Investigator Grant was instrumental to start this exciting collaboration between mathematicians and synthetic biologists.

Precision location can be very important in various engineering applications, such as machining and assembly. In machining, the tool follows a very precise path and a workpiece must be located precisely and stably at a precise position. In assembly, the positions of assembled parts must be assembled easily and overconstraint of the parts must be avoided. One of the common techniques for accomplishing these targets is the use of slots as part features.
