Grinding Compensation of Rod Clamping Error Based on End Mill Grinding
Clamping error of tool bar is an important factor which affects the dimensional precision of tool in grinding process.In this paper,the clamping error of each sampling point on the tool bar is detected by on-machine measurement sys-tem,and the error estimation method of the point on the theoretical tool edge curve is researched.In the actual grinding process,the rod clamping error is inversely compensated to the grinding trajectory,thereby reducing the influence of the rod clamping errors on the tool dimensional precision.By the experiment of grinding four-edged flat end tool and double-edged ball end tool,in the case of large clamping error of tool bar,the tool dimensional precision can be improved by compensation.
