Abstract

PURPOSE:To interpolate data of two optional axes simultaneously by inputting data of two axes as interpolation objects to another two-axis controller and obtaining interpolating pulses from respective two-axis interpolation controllers. CONSTITUTION:Four two-axis interpolating devices 11 are provided for interpolation with respect to four, X-A axes, and data of individual axes are inputted to devices 11 respectively, and devices 11 are provided with terminals P1-P4 to which data of another optional axis is inputted. In case of interpolation with respect to two, X and Y axes, X-axis data as well as Z-axis data from the terminal P1 are inputted to the device 11x, and simultaneously, Z-axis data and X- axis data from the terminal P3 are inputted to the device 11z. When a start signal is inputted, respecitive axial interpolating pulses are obtained from devices 11x and 11z. Similarly, two optional axes are selected and data are inputted to obtain interpolating pulses of these two axes.

５９４５号において提案されている。Conventionally, linear interpolation devices and curved interpolation devices have been used as interpolation devices. Linear interpolation devices include those that interpolate two axes and those that interpolate three or more wheels.In the case of two axes, it is relatively easy to perform interpolation, but for three or more wheels, the control becomes complicated. This creates a problem in that creating a program becomes complicated. Therefore, it was proposed in the patent application filed in 1983 to perform interpolation for three or more wheels using a two-axis interpolation control device.

In other words, when interpolating the X-Y axes using two two-axis interpolation control devices, it is not only necessary to input the X-axis data and Y-axis data to each two-axis interpolation control device, but also to simultaneously input the Y-axis data and Axis data must also be entered. By this, Y
An interpolation pulse for the X-axis corresponding to the amount of movement of the axis and an interpolation pulse for the Y-axis corresponding to the amount of movement of the X-axis are obtained.

The two-axis interpolation control device 11x, which will be described with reference to the case where two-axis interpolation of the X-axis and the Z-axis is to be performed, receives two-axis data from the terminal P along with the X-axis data. At the same time, Z
Along with the axis data, X-axis data is also input and set through the terminal P. When a start signal is input from the terminal (START), an X-axis interpolation pulse is sent from the two-axis interpolation control device tix, and a Z-axis interpolation pulse is sent from the two-axis interpolation control device 11z. Since the interpolation pulse obtained here is a pulse obtained by interpolating data on two axes, the X-axis interpolation pulse and the Z-axis interpolation pulse enable simultaneous interpolation.
