Machine Settings

Use the Machine Settings dialog-box to change the Machine Speed, Number-of-Steps in a machine cycle, and the edit the engineering Units.

Cycling Parameters

Cycles  ∕  Min: See also Note 1

RPM: Revolutions per Minute, of the Machine

MotionDesigner reads this parameter.

Note: Time  ∕  Cycle: You cannot enter 'time ∕ cycle'  . Calculate as: [60 ∕ (Cycle ∕ min)]

Number-of-Steps: [See also Note 4] gives the number of increments that model calculates after each edit of a parameter.

•This is not the number of cam-points.  Use the Cam-Coordinates dialog-box, see Note 2
•Points along a Graph in a Graph FB
•Facets along a Trace-Point

tog_minusNotes...                

Note 1: Cycles ∕ Min does not change the 'animation-speed'. Change the 'animation-speed' with the Animation Speed Slider.

Note 2: To calculate and export cam points for cam manufacture, see Cam-Coordinates dialog-box.

Note 3: We do not display the dimensional units in the graphic-area.

A length dimension that is 100 becomes 3.94 when you change from mm to inches.

An angular dimension that is 100 becomes 1.75 when you change from degrees to radians.

Note 4: Warnings: The model is calculated for each step of the machine cycle.

•Too many Steps?
•A 'high' value does not make the model more accurate.
•If you want to increment the model with small steps, use the 'spin-box' in the Master Machine Angle DRO.
•We re-calculated each time you enter a new value - use your keyboard to enter the new value one time.
•The value becomes the default value, when you exit.

A 'high' value (the actual 'high' value depends on the complexity of the model) will slow the editing of complex models. Make 'high' (greater than 360) when you want to view, in the graphic-area, more points in a graph, facets along a trace-point, complex cams. In all cases, the model does not become more precise with more steps. To precisely set the model at a particular position, use the MMA.
