<![CDATA[The machining process using a combination of steep and shallow strategy is the most widely used strategy for the finishing process on complex models that have many areas of steep walls and shallow floors. Using a single machining strategy on the entire model can lead to long machining times and poor surface finish quality. The steep and shallow strategy can efficiently detect parts of the model that have steep contours and those that have shallow contours. In other words, this strategy can analyze the model surface angle at runtime to identify and divide the machining zone based on the slope angle or commonly called the threshold angle. In this context, the selection of the threshold angle is very important when carrying out the finishing process on free-form surfaces to produce a good surface quality. This study was conducted to determine the optimum threshold angle that can produce the minimum surface roughness between steep areas and shallow areas. Threshold angles that were varied were 20°, 30° and 40°. Machining was carried out using Ballnose type cutting tools with a diameter of 6 mm. Then the stepover and stepdown is 0.1 mm for the finishing process on the surface of the propeller product made of Aluminum by using a CNC Milling machine. From the experimental results, the most optimum threshold angle is at an angle of 40° with an average roughness value in the steep area of 1.9 mm and in the shallow area of 1.3mm and a total average roughness of 1.6mm.]]>

<![CDATA[Fiberglass is a material that is used for several products. This material was chosen because it has many advantages compared to other materials, namely it has better resistance, relatively affordable production costs and is easy to shape. PT.X is one of the manufacturing companies engaged in fiberglass, namely the manufacture of pipes and body from vehicles. In this case study the company still uses hand milling and manual processing. Fiberglass pipe in this company is molded indirectly to the size requested by the customer, therefore a cutting process is needed to get the required pipe length. The blade used specifically is a diamond-coated cutting blade because the fiber material is not heat-resistant. In this research, the researcher wants to design a fiberglass pipe cutting machine with an adjustable holder that can be adjusted so that it can cut various pipe sizes. Making the design of this machine is done using Fusion 360 software. The making of the machine includes the cutting process, grinding process, and welding process. The machine can cut a pipe with a diameter of 100 mm in 20 seconds and for a pipe with a diameter of 500 mm in 1 minute 20 seconds.]]>

<![CDATA[We often see that many of the chairs that tailor tend to have a long shape and the width of the seat is quite narrow. The problem of working attitude faced by the sewing machine while running from a non-ergonomic work chair is the attitude of forced labor such as: lifting the operator up, and lifting the shoulder. If the ergonomic problem is not corrected, it will certainly give an excessive burden, musculoskeletal complaints which will be followed by a decrease in the level of work productivity. Therefore, it is necessary to conduct research in an effort to overcome the problems that arise. For this purpose, research was conducted on the Development and Design of Sewing Operator Chairs Using the Reverse Engineering Method. The number of research samples taken were 26 operators.

<![CDATA[Ice is one of the products produced by cooling machines that can be used to lower the temperature. It is obtained from the process of changing the state of water into ice by cooling below the freezing point of water at 0°C. The process of cooling into ice is done by releasing heat energy which causes the surface of the water to harden. The use of ice-making technology can be done with the Smart Relay-based Fast Freezing Method. This method minimizes the manual system mechanism to increase ice production, one of which is Tube Ice. This research uses an experimental approach method to get the best results which will later be included in the PLC (Program Logic Controllers) and HMI (Human Machine Interface) systems in one Autonic Fort component.
