Computer Numerically Control (CNC) machines are manufacturing machines that are capable of cutting materials with many axes and various types of equipment and operations controlled using a computer. The analysis system used in this software is static structural with linear analysis, because the main focus is to get the value of the stress on the fastening bolts and the stress on the end mill when doing the milling process. The results of the stiffness simulation at the end mill, get the smallest stress results of 0.93783 MPa at a variation depth of feed 1 mm, and get the highest stress results of 5.6272 MPa at a variation depth of feed 6 mm. The result of spindle bolt stiffness simulation shows that the lowest value occurs at 1 mm variation depth of feed, about 1456.4 MPa for equivalent stress, 196.62 MPa for shear stress, and 0.036601 mm for total deformation. Meanwhile, the highest value occurred at the 6 mm variation depth of feed, about 1456.9 MPa for equivalent stress, 196.69 MPa for shear stress, and 0.03664 mm for total deformation. The greater the force that occurs, the greater the stress that occurs on the object, but the stress can also be smaller if the cross-sectional area is larger.
