This calculator should be used as a starting reference range only for shank tools and is based on cutting depth being equal to cutting diameter of the tool. This means that every time you visit this website you will need to enable or disable cookies again.

Usually, the higher the RPM, the better the surface finish becomes.

Experience clear and simple used machine buying and selling. Feed Rate (Inches per minute)

To view all of the table below scroll across to view more information, Feed Rate = RPM x number of flutes x chip load, RPM = feed rate / (number of flutes x chipload), Metric conversion: Divide inches per minute by 39.374 (example: 300 inches per minutes divided by 39.374 = 7.62 metres per minute). If not using coolant, then max surface speed is 50 ft/min. Softer plastic, good for prototyping or for parts that can/should be very flexible. Water based coolant works well; if not using coolant then max surface speed is 125 ft/min.

Proven... DUNMORE's Roll-to-Roll Calculator includes a comprehensive list of calculations and conversions useful for flexible web converting professionals. Good for large moulds and as core for wings. Calculation are as follows: Chip Load = Feed Rate (inches per minute) / (RPM x number of flutes).

If need to get your job done quickly then you can a higher chipload within the specified range. Spindle speed = ${Surface~Speed~(ft/min) \over \pi * \frac{1}{12} * Tool~Diameter~(inches)}$ =. Powerful dust collection is a must, for safety.

=RPM x Chip Load per Tooth x # of Flutes Chip load is usually between 0.001" and 0.010", with exact maximum chipload determined by end mill manufacturers based on the end mill and stock material characteristics, like surface speed. Show Printable Version; 05-10-2007, 09:41 PM #1. Wings - The number of cutting edges on the tool. There are also several factors to be considered when choosing the proper RPM and feed rate. sfm calculator/formula. of Teeth and the Chip Load per Tooth to Determine the Feed Rate (In./Min.) The chip load is a measurement of the thickness of material removed by each cutting edge during a cut. Enter the No. Surface Feet Per Minute (SFPM) Below are the suggested chip load ranges based on material being machined and tool diameter. =SFPM x 3.82 / Tool Diameter We would strongly encourage you to consult us directly on new tool applications.
