Cycling Parameters |
Cycles ∕ Min: (RPM) ( See also Note 1 ) RPM - Revolutions per Minute. It is the model's Simulation-Speed. It is the rate-of-change of the Master-Machine-Angle. MotionDesigner reads and uses this parameter. For example: Degrees: A Motion-Width of 360º is one machine cycle in degrees Seconds: A Motion-Width of (60/RPM) is one machine-cycle in seconds Number-of-Steps: ( See also Note 2 ) Number of calculation points in a machine-cycle. Notes: •number-of-steps and Cam Accuracy - no relationship Do not increase the number-of-steps to increase the accuracy of a Cam. Use the Cam-Coordinates dialog to calculate and save a Cam with any number of points and accuracy. •Number-of-Steps is the number of facets along a Cam in the graphics-area •Number-of-Steps is the number of data-points along a graph - see Graph FB •Number-of-Steps is the number of facets along the curve of a Trace-Point - see Trace-Point •Number-of-Steps is the number of points/dots on the Motor Torque and Speed Curves •Usually, 120 is good. More than 360 is not usually needed. See also: Run menu > Step Forward / Step Backward |

Cycles ∕ Min does not change the animation-speed. Change the animation-speed with the Animation Speed Slider. Do NOT increase Machine-Settings >Number-of-Steps to increase the accuracy of a 2D-Cam! Use the Cam-Coordinates dialog to increase the accuracy of a 2D-Cam you export for manufacture. Number-of-Steps = 120 is ideal. 360 should be the maximum, for nearly all models. To move the model with small steps (increments), we recommend you use the Spin-Box in the Master Machine Angle. If you change the dimension units, you do not change the size of the model. For example: 100 mm is 3.94 inches if you change dimension units from mm to inches. For example: 100 degrees is 1.75 radians if you change dimension units from degrees to radians. In all cases, we do not show you the units in the graphics-area. |
