Optimization Of Mrr And Surface Roughness Parameter During Turning And Drilling Operation

If inserts are used in a drill bit, the temperature of the inserts will be high so, the shank material is very important to remove heat from inserts. Similarly, thermal expansion coefficients of insert and shank material need to be matching to avoid any thermal stresses. The feed marks left on the work piece are due to the relative motion between the milling cutter and work pieces.

Computer numerical control drilling, is a system that uses computers and software to automate drilling.

There are various businesses that can exploit PC numerical control machine hardware, now and then known as CNC machining. The hardware is utilized to manufacture littler pieces, and in addition to make bigger pieces that are to a great degree exact. The gear that is utilized with CNC machining removes at the undesirable material of the bigger piece keeping in mind the end goal to create a littler part. It is a procedure that advantages both the producer and the end-client. What are a portion of the particular advantages of custom CNC machining?

With the rapid development in technology over the past few years it is understandable that many new manufacturing techniques have arisen in order to fine tune the precision of the characteristics and finishes of products. This report will discuss some of these manufacturing techniques and their disadvantages and advantages.

The need for cheap and efficient means of travel coupled with the development of motor vehicles has seen a rapid growth in the automotive industry. The automotive industry encompasses all the companies and activities involved in the manufacture of motor vehicles, including most components, such as engines and bodies (Encyclopædia Britannica, 2014). Even though much of the manufacturing nowadays is done by robots, computers and machines, the strongest and most luxurious vehicles are still considered to be the ones that have had the most human involvement and effort applied on them. This makes simple tools such as the cordless hand drill necessitous in the entire process because of their wide range of uses and applications which will be further discussed in this report. Hand drills today, are used in almost every industry that involves assembling individual components to make a complete structure however, this report will focus on the design of a cordless hand drill specifically for the automotive industry.

Today I will be talking about the research I did on quick change methodology. This is a very fascinating and important topic for the machining process in all plants across the world. The topics that will be covered in this paper are as follows defining quick change methodology and tooling for machining with an overview history and recent advancements, SMED overview history and recent advancements, then a compare and contrast of quick change methodology and SMED, and to wrap up the paper I will illustrate how I can use this information to improve a manufacturing process I am familiar with. These were great research topics and I learned a ton of great valuable information that would be very useful in future endeavors.

There are two type of rotating system in drilling process, rotary table and top drive system. Rotary table make the rotation of drill string through torque applied by the rotary table and by the hexagonal Kelly on the drill floor. It is the old type of rotating system, need more workers on the field because it rotates manually. Top drive system rotate the drill string by using hydraulic or electrical motor that is hang on the mast of the drilling rig (Cherutich, 2009).

The globalization of 21st century and the global population growth had cause the demand of daily products such as food and transportation increases. This market trend had caused the rise of the manufacturing sector. In order to achieve the maximum manufacturing efficiency, some factories have to run their production line for 24/7. Due to the constant evolving of science and technology sector, some of the production requires very high precision and the working environment had become hazardous. Therefore, running the production line barely on man power is dangerous not suitable anymore. In order to maximize the revenues, industries started to import the automotive technology into their production line.

Over 60 to 70 % of machined products have been rejected due to lack of attention in machinability evaluation before machining. This may be lead to indirect affect on cost-effective escalation in production industries. Therefore, predicting the outcome by introducing a change of the preconditions and this will be reflected on the results. Taguchi’s DOE would be more effective and acceptable tool for technical investigations. The desirable machinability evaluation thoroughly obtained by statistical design of experiments (DOE). Reliable results also would be obtained by full factorial or partial factorial technique.

The role of controllable cutting parameters (Speed, feed, depth of cut, width of cut etc.) for economical machining process, optimization have been recognized. F. W. Taylor (1907) showed that an optimum

Abrasive Water Jet Machining (AWJM) is a new machining technique. Abrasive Water Jet Machining is widely used in many industries, including mining and aerospace, for cutting, shaping, and reaming. AWJM is the extended version of Water Jet Machining. AWJM is a non-conventional machining process where the material is removed by impact erosion of the high velocity, high pressure of water and entrained high velocity of fine grit abrasives such as sand (SiO2) or beads of glass on a work piece. The Important process parameters which mainly affect the quality of cutting are hydraulic pressure, traverse speed, standoff distance, abrasive flow rate and types of abrasive material used in the process. The Important quality parameters in AWJM are Material Removal Rate (MRR), Surface Roughness (SR), kerf width and tapering of the kerf. This paper reviews the research work carried out so far in the area AWJM.

Surface roughness has become the most significant functional requirement and it is an index of the product quality. In order to increase the efficiency of hard to machine alloys like titanium and nickel alloys, an Electro Chemical Honing (ECH) process has been employed to achieve highest material removal rate with the best surface qualities. This extended abstract describes the design and fabrication of an indigenously developed tooling setup for ECH of external cylindrical surfaces of Titanium alloys (TI 6AL 4V) and also highlights the key process parameters and their affect on ECH process. The influence of the machining parameters on the surface finish has been investigated and optimized the process parameters for improving the surface roughness is also evaluated. Percentage improvements in surface roughness values Ra and other parameters like electrolyte temperature, composition and concentration were studied while changing the processing time (PT). And also the study of surface characteristics of micro and macro level and micro hardness too examined.

Grinding is a metal cutting operation performed by means of abrasive particles rigidly mounted on a rotating wheel. Each of the abrasive particles act as a single point cutting tool and grinding wheel acts as a multipoint cutting tool. The grinding operation is used to finish the work pieces with extremely high quality of surface finish and accuracy of shape and dimension. Grinding is one of the widely accepted finishing operations because it removes material in very small size of chips 0.25 to 0.50 mm. It provides accuracy of the order of 0.000025 mm. grinding of very hard material is also possible.
