Design of X-Y NC Worktable Based on Microcontroller
——Interpolation part
ABSTRACT
The subject of this design study is mainly based on MCU control system design for CNC
XY table - interpolation part of the design.
Procedures used in the system design by point by point comparison then single-coordinate
positioning, linear interpolation of the two coordinates, circular Interpolation of the two
coordinates by use the stepper motor; on the basis of this, establish quadrant identification
procedures so that XY table can work in four quadrants; and write the code handler ，so CPU
according to the information which have been read(G code and the X-axis and Y-axis
coordinates), output signals to two stepper motor separately for control the table how to move on
X-axis and Y-axis to finish the specified process.
The design of the software programs used KeilμVision2 compile and debug, debugging at
the Proteus and get the results of simulation. the results of the design of the program in the
simulation by Proteus is wonderful, when simulation the program, just need input G code by the
keyboard, stepper motor can control the table through linear interpolation and circular
interpolation to finish plane contour machining.
