Cutting Ellipses - IGM FMR3000 MultiRadius Mode D'emploi

CUTTING CIRCULAR CURVES
Delineate on the work piece axis of the required circle at the angle of 90° with a sign on the required
radius (fig. 1). Affix the cross frame (1) to the work or help piece (fig. 3) with the help of wood screws
(13) or with bonding tape so that the delineated axis intersect the centre of the borings at the end of
the cross frame grooves (fig. 2).The cross frame is now centered on the circle axis. Put the slider A
into the cross frame slide way, shift it to the centre of the cross frame where the both grooves are
crossing and affix to the cross frame (1) with the help of two countersink head screws M4x25 (14).
Remove the slider B from the slide way. Set the required radius and tighten the control screw of the
slider A (fig. 4).
Possible diameter of the circular curve: D = 620 – 3000 mm

CUTTING ELLIPSES

The construction design stipulates the maximum difference in the length of semi-axis of the ellipse
at 205 mm.
PROCEDURE ON CUTTING ELLIPSES
Ellipse size determination
Delineate on the work piece axis of the required
ellipse at the angle of 90° and mark the length
and the width of the ellipse (fig. 1). Affix the
cross frame (1) to the work or help piece
(fig. 3) with the help of wood screws (13) or with
bonding tape so that the delineated axis intersect
the centre of the borings at the end of the cross
frame grooves (fig. 2). The cross frame is now
centered on the ellipse axis.
Major semi-axis setting
(fig .5) Insert the slider A into the centre of the
cross frame and the slider B in the direction of
the major (long) semi-axis. Loosen the control
screw of the slider A, set the required semi-axis
length by shifting the distance rod in the centre
of the slider A pin and tighten with the control
screw (the screw of the slider B is still loose and the rod passes free through the pin).
Minor semi-axis setting
(fig. 6) Rotate the router by 90°. (Cross frame is not rotated! Slider B is in the center of the cross
frame). Set the required minor semi-axis length by shifting the distance rod in the slider B pin; slider A
is still tighten! Setting finished, tighten the control screw of the slider B.
Attention: If the work piece is bent or otherwise crooked, after the tightening of the cross frame, the
sliders may jam in the grooves. Therefore use only flat material!!!
