Start_point Line_ep Endpath |best| — Biesse Cix Macro

He hit . The "Compiling..." bar flashed briefly. Then, the "Ready" light on the massive Biesse machine turned green, blinking softly in the darkness of the workshop.

Elias smiled. The machine knew the way now. He pressed the green button on the pendant, and with a pneumatic hiss, the vacuum clamps sealed the wood to the table. The spindle moved to the start_point .

To create a Bezier curve, the control points are used to calculate the position of a new point on the curve at a given parameter value (t). This parameter value (t) varies between 0 and 1, and its value determines the position of the new point on the curve.

The silence of the night was broken by the song of the cut, a perfect line drawn from a thought in a man's mind to a shape in the wood. biesse cix macro start_point line_ep endpath

"Biesse CIX Macro: Define start_point , execute line_ep , then terminate with endpath ."

MACRO "SIMPLE_LINE" PARAMETERS = start_point, line_ep BEGIN G00 start_point G01 line_ep F2000 M30 END ENDMACRO

To implement the Bissé method using CIX macro, we need to write a command that takes in the control points and the parameter value (t) as input and returns the position of the new point on the curve. He hit

; Move to start point G00 X[start_point.X] Y[start_point.Y] M31 (Spindle ON)

; Linear interpolation to end point (endpath) G01 X[line_ep.X] Y[line_ep.Y] F100

A Bezier curve is defined by a set of control points, which are used to draw the curve. These control points are connected by line segments to form a polygon, where each vertex of the polygon defines a control point. Elias smiled

(defun Bissé-curve (start_point end_point start_slope end_slope) ; Define the control points (let ((control_points (list start_point end_point))) ; Define the parameter value (t) (let ((t (getvar "T))) ; Calculate the position of the new point on the curve (let ((new_point (Bissé-calculate control_points t start_slope end_slope))) new_point)) ))

Here is the logical text/code block for that definition:

He paused. The next command was critical. The architect wanted a tapered channel—thick at the start, thin at the end. But first, the machine had to commit. It had to begin the cut.
