Why Slide Speed And Feed Matter
Slide speed and feed describe how fast a tool, table, or work slide moves during a cut. They also link motion to force, heat, chip load, and finish. A small change can save a tool. A wrong value can damage stock. This calculator helps compare safe motion choices before a job starts.
Practical Planning
Machining is a physics problem with moving surfaces. Diameter sets the circular path. Cutting speed sets surface velocity. Spindle speed converts that surface motion into revolutions per minute. Feed per tooth or feed per revolution then converts rotation into linear slide motion. Travel length and pass count turn that motion into machining time.
Advanced Inputs
The form supports milling, drilling, turning, and straight slide travel. It accepts metric or inch based data. You can enter cutting speed or a known spindle speed. It also includes chip thinning, feed override, extra travel allowance, specific cutting force, and machine efficiency. These settings help produce useful shop estimates.
Output Meaning
The result shows calculated spindle speed, slide feed rate, cutting speed, total travel, time, material removal rate, power, and torque. Feed rate is the main slide value. It tells how far the tool or table should move each minute. Time is based on adjusted travel divided by feed rate. Power is estimated from material removal and cutting force.
Better Decisions
Use the answer as a planning guide, not as a final safety limit. Machine rigidity, coolant, tool coating, holder length, setup quality, and material hardness all change the best feed. Start with a conservative value. Measure chip shape and sound. Then increase speed or feed in small steps. This habit protects tools and improves repeatability.
Record Keeping
The download buttons help keep each calculation with a setup sheet. The example table also shows typical data entry patterns. Use it for training, quoting, and comparing different tools. Consistent records make later jobs faster. They also reduce guesswork when the same material returns.
Quality Review
Check units before each run. Metric and inch values should not mix. Keep diameter positive. Keep efficiency between one and one hundred. Use realistic cutting force values. Review the result table before exporting. This reduces entry mistakes and bad outputs.
