    EXERCISE 4. WEDGE Program a wedge by assigning parameters. Then, by using positioning and increments, do a comparison between the initial point and the final point to be reached. CNC 8070 Parametric programming is handy when trying to change the assignment of parameters to obtain the desired dimensions using the same program.
