Entry Angle Chip Thinning– This Enhancement is based on the Entry Angle (KAPR) of the cutting edge and/or the radius of the cutting edge.Radial Chip Thinning – This enhancement is based on the relation between the radial depth of cut (Ae) and the cutter’s effective diameter (Deff).You have the below options to control how the chip load is calculated. Stage 1 – The system calculates the desired maximum chip load according to the cutter type, diameter, and raw material.The Milling Speed and Feed Calculator automatically calculated the right feed to keep the desired chip load. However, when the radial depth gets smaller, and the cutter is not a 90° shape, you can dramatically increase the feed without getting above the allowed Chip Load. In the case of 90° cutters taking a radial depth of more than 50% of the cutter’s diameter, the chip load is exactly the Feed per Tooth. The Chip Load ( Maximum chip thickness ), is the largest chip that a cutting edge can handle without breaking and still maintain a decent tool-life. Feed Control (Milling) – Customize how the Feeds and Speeds Calculator fine-tunes the Chip Load and Table Feed Best Surface Finish – The calculator will provide the minimum possible feed rate to get good surface finish.Aggressive – The calculator estimates the highest feedrate that the insert can handle at the expense of worse surface quality.Note: The surface quality is proportional to f 2 The calculator will estimate a good balance between productivity (higher Feedrate ) and Surface Quality (lower Feedrate). Speed Control (All Applications) – Customize how the Speeds and Feeds Calculator fine-tunes the Cutting Speed Each grade in the list gets a score that estimates how it compares with your selected grade. The system looks only at the grades that each brand recommends to the application and tries to determine which one best resembles your selected grade. The grade list that appears at the bottom of the results page shows the “closest” grade from each leading brand to your grade. This score estimates “how close” is your selected grade to the “ideal grade”. Besides, it will give your grade a score between 0 and 100. You can specify the grade you are planning to use, and the system will calculate the cutting conditions according to your chosen grade. “Provide A Grade And Get Cutting Conditions”: Additional fields are displayed on the right-hand side in this mode.Each grade gets a score between 0 and 100 that estimates “how close” the grade is to the “ideal grade”. In this mode, the calculator will first determine the ideal grade parameters and list the leading carbide suppliers’ most suitable grades accordingly. “Get Cutting Conditions And Best Grades ”: This is the default mode.Calculation Mode – Customize the relationship between Carbide Grades recommendation and Cutting Speed calculations in “Simple Mode” and on mobile devices, this screen is ignored. You can also hit “Next,” and the calculator will apply the default values. In total, the Milling Speeds and Feeds Calculator support 11 configurations!Ĭalculation Parameters () You can customize how the Speed and Feed Calculator determines the cutting data and get results that are better tuned for your specific application. Milling Cutter Parametersĭepending on the main type of cutter you selected on page four, The calculator will present you with the relevant Sub-Types. If this information is not available use your best judgment or leave the default system value.Choose with the sliders the Insert width and corner radius.Classify the chip breaker/cutting edge geometry of the insert you plan to use.The default frontal angle is 0 (Straight edge insert).Choose with the sliders the Insert width and frontal angle.The best method is to check in the supplier’s catalog how he classifies it.Classify the cutting edge geometry of the insert you plan to use.
