The general steps for tap grinding are as follows

The general steps for tap grinding are as follows: 1. Inspection and evaluation: Check the wear and damage of the tap to determine if it is suitable for grinding. Taps that are severely damaged or excessively worn may need to be scrapped. 2. Cleaning: Remove oil stains, chips, and other impurities from the surface of the tap for subsequent grinding operations. 3. Clamping: Fix the tap on the grinder or specialized grinding equipment to ensure it is firm and not loose. 4. Grinding the front and back corners: According to the geometric shape of the tap, grind its front and back corners to restore the sharpness of its cutting edge. 5. Trimming the spiral groove: If the spiral groove of the tap is also worn, it can be trimmed to ensure smooth chip removal. 6. Inspection and testing: After grinding, inspect the tap to ensure that all its parameters meet the requirements. The grinding effect can be verified through trial cutting or measurement.

Application of RTCP Ball Bar/Detection Bar in Five-axis Machine Tool

Application of RTCP Ball Bar/Detection Bar in Five-axis Machine Tool

RTCP, in the high-end five-axis numerical control system, RTCP is considered to be the Rotated Tool Center Point, which is what we often call the knife point following function. In five-axis machining, when pursuing the trajectory of the tool point and the attitude between the tool and the workpiece, the additional motion of the tool point is generated due to the rotary motion. The control point of the numerical control system is often not coincident with the knife point, so the numerical control system should automatically correct the control point to ensure that the knife point moves according to the instruction set trajectory. This technology is also known in the industry as TCPM, TCPC or RPCP and other functions. In fact, the functional definitions of these names are similar to RTCP. Strictly speaking, RTCP function is used in the double swing head structure and is compensated by the rotation center point of the swing head. The function similar to RPCP is mainly applied to the machine tool in the form of double turntable to compensate for the change of linear axis coordinates caused by the rotation of the workpiece. In fact, these functions are the same, in order to keep the tool center point and the actual contact point between the tool and the workpiece surface unchanged.
