properly formatted CNC program to spot drill (chamfer) and drill thru an aluminum part with 2-meter width x 2-meter length x (thickness from your table)

The holes in a linear pattern will each have a 61-degree angle from the X-axis (or 29 degrees from the Y-axis in each of the 4 quadrants according to the information in the above table with each starting (Absolute) position of (X, Y):

(11., 11.)

(-11., 11.)

(-11, -11.)

(11., -11.)

Drilling sequence from each starting point in the direction away from the origin

Details:

Material of Part: Aluminum with Cutting Speed (C/S) = 50 m/min Use 25 mm diameter x 90 deg spot drill as Tool 1. Use effective diameter in your calculations, and program the chamfer (spotting) before drilling. Use 8.0 mm HSS standard 118 deg drill as Tool 2 (use regular drilling cycle G81) Use 0.1 mm chip load (feed per tooth) Chamfer 0.3 x 45 Deg (Achieved from Spot Drill with Dwell) BTC= 3mm R-Plane=2mm (return to R-Plane before each hole location) Initial Z starting= 25 mm (to pick up tool height offset) Please Include:

Use 4 Program headers minimum. 60 Marks will be awarded for proper format, sequence, style, use of codes, readability, and efficiency. 15 marks will be awarded for proper simulation in NC Plot- free of errors and no tool crashes.

Program Name: Use O(+8838139)
