What is the cutting time when 100mm workpiece is machined at 1000min -1 with feed = 0.2mm/rev ? (Answer) First, calculate the cutting length per min. from the feed and spindle speed. l=f×n=0.2×1000=200 (mm/min) Substitute the answer above into the formula. Tc=lm÷l=100÷200=0.5 (min) 0.5×60=30 (sec)The answer is 30 sec.

Milling is the most common form of machining, a material removal process, which can create a variety of features on a part by cutting away the unwanted material. The milling process requires a milling machine, workpiece, fixture, and cutter. The workpiece is a piece of pre-shaped material that is secured to the fixture, which itself is attached ...

section) or looked up on prepared Tables. The equipment generally consists of a manually operated hydraulic press holding the test piece on a sturdy table and forcing a properly held ball indenter into the surface while avoiding impact. Simple as it looks, it is a precise testing method giving repeatable and meaningful results but only when applied

The results show an influence of the milling on the residual stresses up to a depth of about 60 ... For the finish cut, we assume the bottom face of the pocket is a slot-end milling and the wall face is peripheral-end milling. From Table 6.3, the surface generation rates for the two sequences are 3.7 n and 2.4 nl, respectively. Thus, the finish ...

5. It requires a large amount of force compared to down milling. For down milling, there is a requirement of less amount of force. 6. In up milling, you will get poorer finish. Here, you will get the best surface finish. 7. The chip width increases …

Milling. Milling uses rotating cutters to remove material, unlike turning operations where the tool does not spin. Traditional milling machines feature moveable tables on which the workpieces are mounted. On these machines, the cutting tools are stationary and the table moves the material so that the desired cuts can be made.
