Motion Library Tutorial Switch Radius Calculation

MAN-MLT (Ver 2.0)

3. Know trajectory init point P

), calculate ρ

= ρ(p

, p

) =

[(X

– X

)

+ (Y

– Y

)

]

1/2

4. Drop a perpendicular from the circle center O

on the line L and calculate its

length

h by (2.2.1.1-4)

5. To get switch arc radius, use a proportion

1/(

+ r)

= h/r or

(2.2.3.3-1)

r = hρ

+ hr

(2.2.3.3-2)

and finally the value for r is:

r = hρ

/(ρ

h) (2.2.3.3-3)

Example 2-27

(Motion Mathematic Lib Samples\Circle to Line\ Section 2_2_3_3\

CircleLine_Ex_2_27 – www.elmomc.com)

The circle arc is defined by its radius R = 40000, init angle α = 30

and sweep angle β =

-30

init point (34641, 20000) – Figure 2-27.

Line L target point (130000, 25000).

Coordinates of the circle center O

: X

= 34641 – 40000cos(π/6) = 0,

= 20000 –

40000sin(π/6) = 0;

Define the coordinates of the intersection point P

, Y

). For X

and Y

, use expressions

1 2 ... 45 46 47 48 49 50 51 52 53 54 55 ... 71 72
