Circular Interpolation is a important feature when it comes to CNC machines. WECON recently released a new line of PLC – LX3VM, which has got this function ticked.
In engineering and science, one often has a number of data points, obtained by sampling or experimentation, which represent the values of a function for a limited number of values of the independent variable. Interpolation is utilized here to calculate other values in between, which all together can be used to draw the perfect shape. Linear interpolation is a method of curve fitting using linear polynomials to construct new data points within the range of a discrete set of known data points. Moving a tool along an arc from X to Y with acceptable accuracy is called Circular interpolation. This moving speed controls the speed for each axis so that they can be the defined speed on the defined arc.
When it comes to parts cutting, straight lines and curves are most common ones, which means in CNC programming, linear interpolation and circular interpolation are a must.

Here are a few videos to show how WECON PLC works with interpolation:
