  • List of Process Parameters in Machining – Cutting Velocity

    In such contexts cutting speed becomes irrelevant. Therefore cutting velocity imparts main or primary cutting motion required for machining. Process Parameter – 2: Feed rate (s) The auxiliary cutting motion is provided by the feed rate or feed velocity. Usually the direction of feed velocity is perpendicular to that of the cutting velocity

  • What is Feed Rate in Machining? Its Unit Value Effects and Selection

    Feed rate in milling—Usually 0.05 – 0.10mm/rev. Feed rate in knurling—0.5 – 1.0mm/rev (Cutting speed is usually very small in knurling but feed rate is very high). Pros and cons of improper feed rate. Prior to machining selection of optimum feed rate is crucial as a number of factors are affected by the process parameter.

  • The Right RPM for Diamond Grinding Cutting Drilling Tools –

    Higher RPM leads to less torque which means a higher risk of the tooling losing traction and spin out. Therefore it's always safe to check what the optimal RPM is for the tool you are working with. Grinding Wheels and Blades: Below 7" in diameter these tooling (and thus RPM) are designed for angle grinders.
