TO find the optimal speed and feed rates for a given material sometimes requires a little bit of trial and error. It is important to use the correct endmills compatible with your materials. With that being said, this process isn?t very time consuming. One of the interesting advantages offered by TensileMill CNC Inc. is for our clients to send their specimens to us for a free tensile dog bone preparation. When our engineers are preparing your specimens, most of the time we able to identify the precise speed and feed rate on the 2nd or 3rd cycle run. When the tensile specimens are finally prepared our advanced technical engineers will offer you our best recommendations. We additionally cover the speed and feed rate optimization during the process of training and installation to guarantee that your tensile specimens are prepared perfectly on time.
