The disadvantage of milling machine are: Need proper training for milling operator More expensive to install and maintain Not good at cutting radial cuts More answers below Baran Shafqat B.Sc in Mechanical Engineering, University of Engineering and Technology, Lahore (Graduated 2019) 5 y Not good at cutting radial cuts. As a result, they do not. The cutter is having teeth on its face as well as its side. This machining operation is done on the surfaces which are perpendicular to the axis of the cutter. As a result, there is more material wastage in CNC milling than in additive manufacturing processes, such as 3D printing. A CNC milling machine features a table that automatically moves (or rotates) the workpiece on different planes so the cutting tool can work on it. The Bottom Line If you need more flexibility, have a range of thread sizes and types and require the ability to adjust thread . A sketch of the workpiece is loaded to the computer which is cut on the workpiece by the cutters automatically. The whole milling technology cost are very expensive. In the end, both 5-axis and 3-axis machining have their advantages and disadvantages. Manage Settings 1) If speed is high lead to failure of tool. causing frittering and poor surface finish due to temperature variations.Flank wearVibration.Re-cutting of chips.Burr formation on component.Poor surface finish.Heat generation.Excessive noise.,Which of the following is not the advantage of CNC machines?
