MMI.Boring work is the process of enlarging the hole to the desired size and usually pays less attention togeometric deviations from the results of the boring process, even though it greatly affects the quality of themachining results. In general, a spherical profile is said to be perfectly round if the distance of the pointscontained in the geometric shape have the same distance from a point called the center point. The purpose ofthe study was to determine the effect of spindle speed and feeding speed on the geometric size of the barcketcomponent. The method used in this research is an engineering study with experiments and data collection iscarried out through field observations and analysis of ongoing programs. The independent variable in thisstudy was 0.1 mm infeed depth, with spindle rotation parameters of 400 rpm, 500 rpm, 600 rpm, 700 rpmand 800 rpm. The dependent variable is the geometric deviation of the Bracket Hinge Cab boring results.The control variable is the insert type TNMG332-GN LC5010 which has a feed speed (fz) of 0.1 mm/rev anda roughing size of 104 ±0.30, coolant damin water and ecocool 2700T. The measurement method uses a boregauge/cylinder gauge to determine the effect of variations in machining parameters on the geometry of theboring results with a tolerance of ± 0.30 mm and takes 4 axes of measurement, namely X, Y, X', Y'. From theresearch that has been done that the parameter with the smallest geometric deviation is obtained in the fourparts with a spindle rotation (n) 700 rpm, which is the expected result because the geometric deviation is70μm, still within the tolerance limit of ± 0.30 mm and has a roughness level of 9.278 Ra. The greater thevalue of the cutting speed (Vc), the smaller the geometric deviation that occurs.

Road surface texture is an important factor in providing safety and comfort for road users. One of the factors influencing the wear of tires on F30 type sedans wi th 1998cc engines is the thickness of the grooves and the treadwear indicator. The theoretical calculations made in research on tire use are done by correlating between the average speed of the vehicle, the load on the rear wheels, and the road surface to the centrifugal force, traction, and rolling resistance of the tire with a load of 2 passengers resulting in centrifugal force on tires 372, 21 kN, traction 1034.92 kN, and rolling resistance 17.59 kN. Tests performed on three different tire brands show that the faster the driving speed, the faster the tire flow erodes, the tire flow indicator or treadwear will decrease by 0.0041 mm to 0.0048 mm per hour. This proves that the test of this theoretical calculation can be a reference in average driving speed.","PeriodicalId":480793,"journal":{"name":"KALPIKA","volume":"1004 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135683702","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
