Cutting Speed:
Cutting speed should be moderate, and lower cutting speeds are generally recommended to avoid overheating and tool wear. For stainless steel, the cutting speed is usually between 50 and 100 m/min.
Depending on the tool material and workpiece hardness, trial tool testing may be necessary to determine the optimal cutting speed.
Feed Rate:
Feed speed should be appropriate to ensure chip removal and tool life. It is generally recommended to use smaller feeds to reduce cutting forces and tool wear.
For stainless steel, the feed rate is usually between 0.05 and 0.15 mm/tooth.
Depth of Cut:
The cutting depth should be determined based on the hardness of the workpiece and the strength of the tool to avoid tool breakage and workpiece deformation.
For stainless steel, the cutting depth is generally recommended to be between 0.5 and 2 mm, adjusted according to the characteristics of the tool and workpiece.
Cutting Method:
Choose the appropriate cutting method, such as down milling, up-cut milling or inclined milling, to achieve the desired machining effect.
For stainless steel, climb milling is generally recommended to reduce cutting forces and tool wear.
Cooling and Lubrication:
In stainless steel milling, cooling and lubrication are crucial. Use appropriate coolant or lubricant to reduce cutting temperatures, extend tool life and improve machining quality.
Make sure the coolant or lubricant can fully cover the cutting area and drain the chips in time to avoid overheating of the tool and workpiece.
Trial and adjust:
Before starting actual machining, conduct a trial tool test to determine the best cutting parameter settings.
Adjust according to the actual processing effect, including cutting speed, feed speed, cutting depth, cooling and lubrication method, etc.
