Machining

The energy used emit big amount of gases like CO2 and NOX which foster the acid rain.  Painting/coating/plating. High quantity of pollutant and toxic gases emitted has forced to manufacturers change from organic- based to water- based paints.  Machining. The big amount of waste for this process is managed by recycling  Joining. Welding is the predominant joining process with gas emission. NIOSH has set some requirements for these processes in terms of the welfare of the workers.  Plastics…

runner trims off automatically. While designing a gating system, it is necessary to select the suitable location for the gate. Consequently, following principles must be followed.  Gate location should be chosen in parting surface, to facilitate machining and maintenance.  Location of the gate should be able to balance flow in all directions, or to achieve flow along the axis of the most critical dimensions.  Locate the gate on the thick wall to ensure the cavity can be filled completely and…

One case is when parts happen to come out undersized or oversized during the machining process. In these cases, if critical thinking was not applied to the thoughts of reasoning why this incident occurred, one may assume that it was the technician that is at fault, they must not have made the correct measurements, or pushed the wrong…

Kulwant originally wanted to be a plant breeder and had an interest in plant genetics. He loved plants and wanted to do research in developing new plant varieties. Therefore, he got a Masters of Science in Plant Breeding. After University, he worked as a Research Assistant in Pulse Breeding. Then he had to leave his job after only working 9 months to immigrate to Canada. Unfortunately, when he got here he couldn’t find any jobs related to plant breeding, so he was forced to do odd jobs to make a…

All of these habits are very important and can improve my life and cause myself to be more productive in a work environment and in my personal life.All of these habits are very important and can improve my school life and produce a more productive in a school environment.The first habit is Habit 1 proactive by Stephen Covey, is that it is a more positive way of reacting to problems or things in a workplace or school environment.it gives many examples and ways to be proactive such as, Take…

In this research, we study the bi-objective economic lot scheduling problem (ELSP) considering deteriorating items in which the shortage is allowed. The considered problem is NP-hard since the ELSP is already shown as NP-hard problem. The goal of this study is to minimize two objectives simultaneously; 1) setup and inventory holding costs including deteriorating factor, 2) total number of stock out units of each item during each period. The studied ELSP problem, adopts extended basic period…

I have always felt like I was an “old sole”, and by that I mean I have never felt my age. I always hung around people much older than myself and have gained much insight to what life was all about. I knew what I wanted at 14 and that was to have a child. My passion to be a mom was very strong. With all the negativity that came with this, I was still determined to succeed and at age 16, my son was born. I proved myself to be a good mother. I felt a lot of people didn’t think that I was going to…

composition of compaction process will produce the green body. This powder compaction process is chosen based on its advantages because it can save time and money in term of manufacture in mechanical production. These methods also have less or no machining. The composition will be press by using Carver press machine with 2.5 MPa load for 5 minutes for each sample. Figure 3.6 shows the carver press machine. Figure 3.6: Press Machine for powder compaction (Carver Press Machine) Figure 3.7:…

moulds. Examples of formative processes are stamping, forging, drawing, rolling or extruding. Subtractive processes on the other hand remove layers of material to form the final part. Turning, milling, grinding, electro chemical machining (ECM), electric discharge machining (EDM), etc. are all examples of subtractive processes. Additive processes, which is the most recent manufacturing process, produces parts by building the part up in a layer-by-layer manner.…

finished product, these can be direct materials, direct labour and direct expenses related to the production of the finished product. Prime cost is the total of all direct costs (material, labour and expenses). Quantity x price rate = total E.g. for machining department ‘Carom’: 450 x 12 = 5,400 1,200 x 8 = 9,600 2,230+5,400+9,600=17,230 Total prime cost for Order 2169 ‘Carom’: 17,230+8,370+9,650 = 35,250 Total prime cost for Order 2170 ‘Horal’: 12,900+14,480+11,370 = 38,750 Total prime cost…
