Advanced Linear And Circular Interpolation 150401b Flashcards
List 5 things all motion types have in common
They are modal Must program an endpoint Absolute or incremental Only moving axes to be included Drop the leading zeros
Describe how to program X, Y and Z axis for hole cutting tools like drills, and Reamers that Plunge in the Z axis while Machining
Program Center of cutting tool in X & Y axis and extreme tip of the tool in Z axis
What are the two ways to determine the X & Y coordinates of a Milling cutter tool path?
Centerline path, all coordinates to Milling Cutters Center
Work surface path, uses cutter radius compensation, use workpiece Dimensions to get X & Y coordinates
What is the resolution of most Machining centres?
0.000039 inch or 1 micron or .001mm
Every motion command requires an endpoint. What is the start point?
The previous motion commands endpoint
What G-Code specifies inches per minute, inches per Revolution?
G94
G95
What is the point of reference with incremental positioning?
The cutting tools current position
When programming the Milling Cutters Centerline path, to determine the R value you must, ______ cutter radius to the work surface radius for an outside radius and ______the cutter radius from the work surface radius for a fillet radius
Add, subtract
If programming a 1 inch radius with a half an inch End Mill using Centerline programming what R-value would you use?
Radius equals workpiece radius, plus radius of cutter.
1.250
To determine which I, J, or K you must use and which direction of vector, you should draw arrows from …
Start of the arc to centre of the arc in each axis
How would you program a full circle in one command using R word or I & J directional vectors?
The start point is the same as the endpoint for I and J. R-word can’t do it
What is the rule for determining Arc motion Direction?
View circular motion from positive side of uninvolved axis
