6. Automated feed control
Automated feed control in a skate sharpening machine governs the rate at which the blade traverses the grinding wheel. This system replaces manual operation with a programmed, often computer-controlled, process. Its primary function is to ensure consistent material removal along the blade’s length, resulting in a uniform hollow and edge profile. Manual feed control introduces variability, potentially leading to uneven sharpening and suboptimal performance. Automated systems mitigate this risk by maintaining a constant feed rate, regardless of variations in blade hardness or operator skill. The cause is an input parameter, feed rate, that affects the output of a sharpened blade.
The incorporation of automated feed control enhances the repeatability and efficiency of the sharpening process. By eliminating human error, these systems produce consistent results across multiple sharpenings, allowing skaters to maintain a reliable and predictable blade feel. Further, automated feed control can significantly reduce the time required to sharpen a pair of skates, increasing throughput for sharpening services. A practical example is the use of programmable logic controllers (PLCs) to regulate the feed rate based on pre-defined sharpening profiles. The PLC monitors the wheel’s rotation and adjusts the blade’s movement to achieve the desired hollow depth and edge angle. The system also reduces the occurrence of excessive heat buildup in the grinding area by optimizing the blade to wheel contact time and pressure. This leads to reduced blade damage during sharpening and enhances the overall blade sharpness.
