摘要： When creating other tool path from two tool paths for cutting a work accurately and efficiently, the data on the first tool path is composed of a position vector and a direction vector of a tool for use when the work is cut while moving the tool. The data on the second tool path is composed of a position vector and a direction vector of the tool for use when the work, which has been cut according to the first tool path, is further cut. A computer uses the first tool path data and second tool path data to calculate a position vector and a direction vector of a medium tool path that is between the first tool path and second tool path.

摘要： A module has an IC for communication control (a PHY unit) and an EEPROM (or MCU) connected to the PHY unit via an I2C bus. When a software reset is triggered while the PHY unit reads non-volatile register (NVR) data from the EEPROM (or MCU) via the I2C bus, the module causes an I2C interface circuit of the PHY unit to forcedly toggle and send a clock signal to the EEPROM (or MCU) via the I2C bus to make the EEPROM (or MCU) recognize that interrupted communications via the I2C bus are pseudo completed.
