ME 576 Lab. 3 Instruction Name Generate a manual part programming for the part shown below with finished dimensions using parametric programming with L variables and subroutines. Assume that the part being machined has been forged and is uniformly slightly larger that the final dimension by 0.5 mm. The coordinate of the starting point is (170cos30 o ,170sin30 o ,0). The machining is to be performed by using an endmill of 10 mm diameter in the clockwise direction. Feedrate to be used is 200 mm/sec and the spindle rotational speed is to be set at 3500 rpm in the clockwise

Unformatted text preview: direction. The tool geometry is stored in the parameter D1 (already stored) and held in the magazine with index number 2. The width of cut in the z-direction during cutting is 9.8 mm and hence the tool must be fed into the negative z-direction by 10mm. Consider the tool geometry compensation. Note : generate the program from A and B and repeat the pattern using subprograms or loops. For your convenience, the following information on the connecting points is provided. You are welcome to calculate your own values....
