Numerical controller

Abstract

Abstract PURPOSE:To increase the operability, by determining a tool path, through the provision of a memory storing the shape of blade of a tool and the shape of processed work programmed and through the correction of the shape of the processed work in matching with shape of tool. CONSTITUTION:Blade tip information inputted from a keyboard 12 is stored in a memory 8. The final finished shape instructed from the keyboard 12 is stored in a memory 7. A central processing unit 10 makes a corrective calculation for a blade angle adding a given angle to the shape of tool blade tip shape of a tool number instructed by the memory 8 to the memory 7 to determine the processed shape by the correction of the tool blade tip. A data output circuit 14 receives a controlled variable of tool position from the central processing unit 10 to control the tool position for processing. The remaining part at the process is processed at the next process similarly through the designation of another tool.
