- 圆弧插补方法可以通过提供圆弧的起点、终点和半径来画弧。下面是一个用C#实现的圆弧插补方法的示例代码:
-
- ```
- public void DrawArc(Point startPoint, Point endPoint, int radius, bool isClockwise)
- {
- // 计算圆心坐标
- int centerX = (startPoint.X + endPoint.X) / 2;
- int centerY = (startPoint.Y + endPoint.Y) / 2;
- double distance = Math.Sqrt(Math.Pow(endPoint.X - startPoint.X, 2) + Math.Pow(endPoint.Y - startPoint.Y, 2));
- double halfChord = Math.Sqrt(Math.Pow(radius, 2) - Math.Pow(distance / 2, 2));
- double angle = Math.Atan2(endPoint.Y - startPoint.Y, endPoint.X - startPoint.X);
- if (isClockwise)
- {
- angle += Math.PI / 2;
- }
- else
- {
- angle -= Math.PI / 2;
- }
- int circleX = (int)(centerX + halfChord * Math.Cos(angle));
- int circleY = (int)(centerY + halfChord * Math.Sin(angle));
-
- // 计算外接矩形
- int left = centerX - radius;
- int top = centerY - radius;
- int right = centerX + radius;
- int bottom = centerY + radius;
-
- // 绘制圆弧
- GraphicsPath path = new GraphicsPath();
- path.AddArc(left, top, radius * 2, radius * 2, (float)Math.Atan2(startPoint.Y - circleY, startPoint.X - circleX) * 180 / (float)Math.PI, (float)Math.Atan2(endPoint.Y - circleY, endPoint.X - circleX) * 180 / (float)Math.PI - (float)Math.Atan2(startPoint.Y - circleY, startPoint.X - circleX) * 180 / (float)Math.PI);
- Graphics g = this.CreateGraphics();
- g.DrawPath(new Pen(Color.Black), path);
- }
- ```
-
- 这个方法接受起点、终点和半径作为参数,并且可以指定是顺时针还是逆时针画弧。它首先计算出圆心坐标,然后根据起点、终点和半径计算出外接矩形。最后使用GraphicsPath类的AddArc方法绘制圆弧。
-
- 使用C#编写CNC圆弧插补方法可以实现高效的运动控制。下面是一个简单的C#圆弧插补方法的示例代码:
-
- ```
- public void ArcInterpolation(double x, double y, double i, double j, bool clockwise)
- {
- double radius = Math.Sqrt(Math.Pow(i, 2) + Math.Pow(j, 2));
- double centerX = x + i;
- double centerY = y + j;
- double startAngle = Math.Atan2(-j, -i);
- double endAngle = Math.Atan2(y - centerY, x - centerX);
- if (clockwise)
- {
- if (startAngle < endAngle)
- {
- startAngle += 2 * Math.PI;
- }
- }
- else
- {
- if (startAngle > endAngle)
- {
- endAngle += 2 * Math.PI;
- }
- }
- double angle = endAngle - startAngle;
- double step = angle / 100;
- for (int k = 0; k < 100; k++)
- {
- double currentAngle = startAngle + k * step;
- double currentX = centerX + radius * Math.Cos(currentAngle);
- double currentY = centerY + radius * Math.Sin(currentAngle);
- //将当前坐标发送给CNC控制器
- }
- }
- ```
-
- 这个方法接受四个参数:起点坐标(x, y)和圆心相对于起点的偏移量(i, j),以及一个布尔值,表示圆弧是顺时针还是逆时针方向。方法首先计算圆弧的半径和圆心坐标,然后计算起点和终点的角度,并根据顺时针或逆时针方向调整角度。最后,方法使用100个步骤计算圆弧上的每个点,并将每个点的坐标发送给CNC控制器。

- 直线插补是数控机床中常用的一种插补方式,可以实现直线和圆弧的插补。下面是一个用C#实现直线插补的简单示例:
-
- ```csharp
- public class LinearInterpolation
- {
- public static List
Interpolate(PointF start, PointF end, float step) - {
- List
points = new List(); - float dx = end.X - start.X;
- float dy = end.Y - start.Y;
- float distance = (float)Math.Sqrt(dx * dx + dy * dy);
- int steps = (int)Math.Ceiling(distance / step);
- float xIncrement = dx / steps;
- float yIncrement = dy / steps;
- float x = start.X;
- float y = start.Y;
- for (int i = 0; i < steps; i++)
- {
- points.Add(new PointF(x, y));
- x += xIncrement;
- y += yIncrement;
- }
- return points;
- }
- }
- ```
-
- 这个示例中,我们定义了一个`LinearInterpolation`类,其中包含一个静态方法`Interpolate`,该方法接受起点、终点和步长三个参数,并返回一个包含所有插值点的列表。在方法中,我们首先计算出起点和终点之间的距离,然后根据步长计算出需要插值的点数。接着,我们计算出每个点的坐标增量,然后循环计算每个插值点的坐标,并将其添加到列表中。最后,我们返回包含所有插值点的列表。

直线插补:
- public void LinearInterpolation(double startX, double startY, double endX, double endY, double feedRate)
- {
- double deltaX = endX - startX; double deltaY = endY - startY;
- double distance = Math.Sqrt(deltaX * deltaX + deltaY * deltaY);
- double stepX = deltaX / distance;
- double stepY = deltaY / distance;
- double currentX = startX;
- double currentY = startY;
- double remainingDistance = distance;
- while (remainingDistance > 0)
- {
- double moveDistance = Math.Min(remainingDistance, feedRate);
- currentX += moveDistance * stepX;
- currentY += moveDistance * stepY;
- //控制执行机构进行相应的运动
- remainingDistance -= moveDistance;
- }
- }
- public void L直线插补
- (double startX, double startY, double endX, double endY, double f进给速率)
- {
- // 单轴向剩余距离
- double deltaX = endX - startX; double deltaY = endY - startY;
- // 平方根节拍 平方根
- double distance = Math.Sqrt(deltaX * deltaX + deltaY * deltaY);
- // 单轴距离占比
- double stepX = deltaX / distance; // x轴单步距离
- double stepY = deltaY / distance;
- // 当前的位置
- double currentX = startX;
- double currentY = startY;
- // 平方根节拍
- double remainingDistance = distance;
- //================================================
- // 剩余平方根节拍
- while (remainingDistance > 0)
- {
- // 移动距离 最小步距 平方根距离 进给速率
- double moveDistance = Math.Min(remainingDistance, feedRate);
- //单节拍【单步运动】
- currentX += moveDistance * stepX; // 单步距离
- currentY += moveDistance * stepY;
- //========================================
- //控制执行机构进行相应的运动
-
-
-
- // 剩余节拍数 单步节拍
- remainingDistance -= moveDistance;
- }
- }
